Configuring Cisco 79xx phones with Asterisk

This page documents how you configure a Cisco IP phone with Asterisk.


By default most Cisco VoIP phones come configured for Call Manager, which uses the 'Skinny' protocol - SCCP.
Asterisk has 2 implementations for this channel (required for the 7910/20):

• Skinny implements a very basic set of telephone functions and ships with asterisk.
• SCCP has implemented more of the SCCP protocol, so some class 5 features (hold, transfer, forward, etc) should work.

However, the 7905/7912 and 7940/60 can be reconfigured to use SIP (recommended for use with Asterisk):
http://www.cisco.com/en/US/products/hw/phones/ps379/products_tech_note09186a0080094584.shtml

The 7905 doesn't have Speakerphone (only a speaker for call monitoring or on-hook dialing), its SIP image has by far the best user interface of all cisco SIP phones, plus it's nicely compact, and the display even has a higher resolution than that of the 7960. The 7912 is the same as the 7905, but with a built-in ethernet switch.

The 7912/05 phones use a different configuration file format and syntax; for more information about configuring these phones please refer to Cisco 7905/7912 IP Phones.

With the right Cable, 79xx series phones can use standard POE injectors. They also work out of the box with Aironet power injectors. (N.B., the wrong cable may damage your phone!)

Cisco 7940/7960 SIP Phone Software Images
Cisco's SIP phone software images including versions 3.0, 4.4, 5.3, 6.x and 7.x work well with Asterisk. Features have been implemented and caveats (earlier problems) corrected with each release. The v5.x and v6.x images have incorporated a software security feature that makes it impossible to revert back to earlier images, although reverting to earlier versions is possible within the same major release (i.e. 7.5 firmware can be rolled back to 7.4 firmware with no problems). Version 6.0 SIP image has been very stable for many Asterisk users. The new version 7.x images are largely untested, but feature mainly bug fixes, not new features.

http://www.cisco.com/pcgi-bin/tablebuild.pl/sip-ip-phone7960

It appears to be impossible to upgrade directly from v3.x to v8.x (probably any version prior to v6.x), I had to upgrade to v6.3 first. It is very hard to find a copy of this the v6.3 firmware (not even on Cisco site). Search for P0S3-06-3-00.zip or get it at http://www.xs4all.nl/~graver1/cisco/SIP-7960/P0S3-06-3-00.zip

Version: v8.3
The file from cisco is designed for the cisco call manager software and is a ".cop" file.
The file from cisco is designed for the cisco call manager software and is a ".cop" file. This file is just a GZIP compressed TAR file. Just ungzip and untar the file to extract the the new files for the phone. It installs just like the version 7 software with a loader and an application file. The standard ZIP file should be released soon.

• No longer lists server IP on display for caller's number.
• At least on the 7960, this release seems to break the Asterisk qualify sip.conf setting. The phone shows as unreachable just after it registers. If you set "qualify=no" it works.
• I have also seen some other phone display strangeness with this release on the 7960

http://www.cisco.com/en/US/products/sw/voicesw/ps2156/prod_release_note09186a008068f6c5.html

Version: v8.2

• Using the existing config files (that worked with v7.x) it seems to work, execpt the CID now displays the IP address also.
• new config params:
  • line1_contact: number, changes the username part that is sent in the sip Contact: header
  • transfer_onhook_enabled: 1 or 0. If enabled, a call will be transferred when the handset is hung up (rather than having to press the Trnsfr button again. The original behaviour still works.)
  • call_manager1_addr and call_manager1_sip_port, not sure what difference these make
  • dscpForAudio: id, tag audio packets for qos with this dscp id, replace tos_media field
  • connection_monitor_duration: sec
  • encrypt_key: 32hexdigits, careful with this one, some config encryption support or similar
  • xml_card_dir and xml_card_file, actually these appeared earlier, doesnt seem to try load the card.xml over tftp for this, anyone know?
  • Current bug: There appears to be a bug in v8.2 that causes the phone to be unable to register with Broadvoice's SIP proxy. Downgrading the firmware appears to resolve the issue.

v8.2 Release Notes:
http://www.cisco.com/en/US/products/hw/phones/ps379/prod_release_note09186a00806216ab.html


Version: v7.5

• There seems to be a bug in the 7.5 SIP software (at least on the 7960) that cause the phones to drop registration with Asterisk and not re-register. A phone reboot forces them to reregister for a time. 7.4 with the same configuration does not seem to have the same registration problem. It's unclear exactly where the issue exists (phone config, asterisk, time settings, etc). - doretel
• Firmware 7.5 breaks RFC compliance, by not ACKing a 487. http://bugs.digium.com/view.php?id=5336. Also, we have experienced 7940/60 phone hangs/reboots related to "XML Parse Error" displayed on phone screens. Reverting to v.7.4 eliminated these problems. -vechers (The "XML Parse Error" problem and the previously mentioned fix confirmed by rrizzi7210)

v7.0 and up:

• A new design approach is used to store the existing software base in the Cisco 7940 and Cisco 7960 telephones. The new approach utilizes a "run from flash" design to use the Flash and RAM memory available more efficiently.
• Bugfix: Media takes 0.4 sec to be set up (finally...)
• Bugfix: HTTP requests fail, sysbufs get hung
• Numerous other bug fixes, too many to mention (see release notes below)

• Auto Answer (2-way paging conversation without picking up handset)
• DHCP Option 66
• Directory Enhancements (user can add/change/delete entries in Personal Directory)
• DSP (new digital signal processor)
• DSP Alarms, Debugging Aids, and Logging (help diagnose problems)
• Enhanced Tone and Ring Support (support for more complex tones and ringing patterns)
• Hot Line / Speeddials (each line button can be programmed to act as a speeddial button)
• Local Call Forwarding (redirects incoming calls to another extension/URL)
• Message Waiting Stutter Tone
• Multiple Call Appearance (receptionist style, all lines have the same extension)
• Outbound Proxy Redesign (improves use of outbound proxy based on multiple DNS records)
• SIP Call Statistics (call statistics sent in BYE / 200 OK messages)
• Resolved Caveats (several previously documented problems have been resolved)

Cisco 7941/7961 SIP Phone Software Images

Cisco's SIP phone range now includes the 7941/7961, as new firmware v8.0(1) came out for these that supports SIP in March 2006. Previously some v7.0 releases of SCCP had been released. These phones look physically identical to the 7940 phone with the exception of the much better quality display which can display grey shades, however the software for the 7941/7961 appears to have major differences to the 7940/7960 software.

Release notes for v8.0 SIP are at http://www.cisco.com/en/US/products/hw/phones/ps379/prod_release_note09186a0080621246.html

Note that the release notes clearly state at the top of the document that "This SIP firmware was designed and tested to interoperate with Cisco call control, most notably Cisco Unified CallManager version 5.0. Although this SIP deployment is IETF RFC 3261 compliant, it is not supported by Cisco TAC or Engineering for use with non-Cisco call control systems.". So YMMV if you call the TAC for support.

The v8.0 software for the 7941/7961 has these significant differences over the v8.0 software for the 7940/7960:

• The built-in web server previously only in the non-SIP images is now in the v8.0 SIP builds
• The phone does not appear to support the old style config files, all configs for this phone need to be in XML
• The phone does not appear to support telnet, but instead supports SSH-2.0, although this appears to be undocumented on CCO. At this stage unsure what the default user/password is
• The config file name is therefore now SEP<mac-address>.cnf.xml
• Upgrading the firmware load involves the phone uploading 5 signed binary files: jar41sip.8-0-1-18.sbn, cnu41.3-1-1-15.sbn, apps41.1-1-1-15.sbn, dsp41.1-1-1-15.sbn, and cvm41sip.8-0-1-18.sbn (this was for release load version 8-0-2SR1-0-1 which is the latest as of early April 2006). These phones can be upgraded and the protocol support changed via the normal means of adding <loadInformation>term41.default</loadInformation> to the .cfg.xml file

At this stage, documentation on the format of the xml config file for SIP has proven to be extremely hard to find. Cisco are likely assuming that all adopters of this phone will be running it in a CallManager environment whereby the configs are automatically generated by the CCM. If you do find some or have access to a CallManager 5.0 which can generate these files, please document the basic format so others can configure these phones for SIP in a non CCM environment.

More information on this new config file format and this new series of phones can be found at the 79x1 xml config page Please edit it and improve it as much as you can as information of the nature in that document has not to date been easy to find.

Software Upgrade Requirements

All software images are upgraded through a TFTP server at your location. If you don't have one, several free Unix and Windows packages are available via the Internet. The specific instructions as to exactly how to accomplish the upgrade should be reviewed from Cisco's web site as the exact steps (and possible backout steps) may change from version to version.

The TFTP server directory must include the following files as a minimium (most are upper/lower case sensitive):

• OS79XX.TXT (The content of this file is solely the software image filename stripped of the .bin, i.e. P0S3-06-1-00)(Contains the universal application loader image in 7.x)

Note:(The 7.1 image upload needs to be spelled P003-07-1-00 in the OS79XX.TXT and P0S3-07-1-00 in the SIPDefault.cnf)
Note:(7941G does not fetch OS79XX.TXT when upgrading from SCCP 8.x to SIP 8.x)

• P003-xx-y-zz.bin (Nonsecure universal application loader for upgrades from pre-5.x images.)
• P003-xx-y-zz.sbn (Secure universal application loader for upgrades from images 5.x or later.)
• P0a3-xx-y-zz.loads (File that contains the universal application loader and application image, where "a" represents the protocol of the application image loads file 0-SCCP, S-SIP, M-MGCP.)
• P0a3-xx-y-zz.sb2 (Application firmware image, where "a" represents the application firmware image.)
• SIPDefault.cnf (Contains generic parameters for all Cisco phones at your location)
• SIP00036BAAD139.cnf (Where the last 12 hex digits is the MAC address of your Cisco phone) Sample php script to create the cnf file.

In addition, the following optional files may also be present in the TFTP directory:

• dialplan.xml (contains entries like "9,1...." that cause the phone to automatically dial after a match)
• RINGLIST.DAT (a list of ringing tones to be downloaded, like ringer1.pcm)
• ringer1.pcm (a ringing tone to be downloaded to the phone)

See also: John Todd's examples

*** Simplify Updates (Auto-Loader Support) ***

This will save you alot of wasted time trying to update newer firmware! For easiest, direct firmware updates from say factory installed SCCP images direct to latest SIP firmware (e.g. SCCP v3.1 to SIP v7.4) — add the following files to your TFTP directory to assist the SCCP based generic Auto-Loader added as of v5.x to Cisco's SIP/SCCP images:

• XMLDefault.cnf.xml
• xmlDefault.CNF.XML

Due to inconsistent coding by Cisco, different firmware may look for different case-sensitive versions of the same file, thus the need for at least the two variations above to cover new phones and a good portion of older one's. Additionally, here is a usable example of the XML content that should be inserted into the files (be sure and update with the firmware version you wish to load, and match the SIPDefault.cnf and SIPxxxxxxx.cnf file's "image_version=" entries to match!):

Just add the loadInformation lines relevant to the phone that you have.

Misc

See reboot.pl (down as of late - Internet Archive link: http://web.archive.org/web/20060427051951/http://mklein.bendtel.net/mkreboot.pl). A perl script to handle remote rebooting of the 79xx class phones (useful for multiple-phone upgrades). Requires Net::Telnet.

NOTE: For Reference, reboot.pl has been moved to http://www.nmedia.net/~mklein/reboot.pl. Still Requires Net::Telnet.

So you blew up your 7940/7960 trying to load new firmware

Logo Displayed on 79XX Screen

A non-Cisco logo can be displayed on the 79XX screen. Cisco's documentation suggests the logo be a Windows Bitmap form (*.BMP) with 256 colors and 90 x 56 pixels in size. Only two colors are displayed, black or white. The image must be saved in greyscale format. In GIMP it is Image->Mode->Greyscale. If the size of the logo is larger then this specification, the phone will rescale to fit (within reason). Microsoft Paint and many other applications can be used to create the logo image.

Once the image is created, place the *.BMP file on any web site available to you (suggest /asterisk/mylogo.bmp, where the /asterisk directory is not freely advertised).
Modify the SIPDefault.cnt file entry to point to the web site:
logo_url: "http://www.mywebserver.com/asterisk/logo.bmp"
and reboot the Cisco phone.
Note: the smaller the logo file, the quicker it will load. Typcial logo files should be around 10k bytes.

Note: 7940/7960 phones actually display two colors at 2-bit depth, or four solid colors. For best results creating images/logos that don't dither and degrade, use #000000 (black) and #FFFFFF (white or clear on the LCD display), then #404040 (dark grey) and #808080 (light gray) as your alternate solid colors (or as the antialiasing colors for excellent results).

Company Telephone Directory

The 79XX phones have four panel keys labeled as Messages, Services, Directories, and Settings. The Directory key can be programmed to view your company's telephone directory by displaying Names and Telephone Numbers that are stored on any web site available to you.
Modify the SIPDefault.cnf file entry to point to the web site:
directory_url: "http://www.mywebserver.com/asterisk/directory.xml"
The phone must be rebooted in order to read the above file.
The web site file /asterisk/directory.xml should include xml entries like:


Note: Each time a user presses the Directory key and accesses the External Directory option from the menu, the phone will access the contents of this html file and display whatever text entries included in it. Therefore, changes to the html file do not require any futher rebooting of the Cisco phone. Cisco has published Cisco IP Phone Services Application Development Notes (CMXML_App_Guide.pdf ) that further explains options and file contents.

Asterisk Cisco 79XX XML Services

Services Button

The 79XX phones have four panel keys labeled as Messages, Services, Directories, and Settings. The Services key can be programmed to execute CGI scripts that are stored on any web site available to you. The CGI scripts can perform any action that you are capable of programming. None are provided by Cisco.
Modify the SIPDefault.cnf file entry to point to the web site:
services_url: "http://www.mywebserver.com/asterisk/myscriptpage.html"
The phone must be rebooted in order to read the above file.
The web site file /asterisk/myscriptpage.html should include entries for each service that you plan to make available to your phone users. The exact content and syntax is also documented in the Cisco IP Phone Services Application Development Notes (CMXML_App_Guide.pdf ) noted above.

Messages Button

When the Messages button is pressed, you can cause the phone to directly dial an extension in your asterisk dialplan. Just configure the phone as:
       messages_uri:  "<extension>"
where <extension> is what you wish the phone to dial when the Messages button is pressed. You can then catch the call in either a standard VoiceMailMain() invocation a la
       exten => _42,1,VoiceMailMain()
or, be cute and bypass entry of mailbox number and password a la
       exten => _42,1,VoiceMailMain(s<mbox num>)
To make the Messages button work for any extension (assuming your extensions are numbered appropriately), use:
       exten => _42,1,VoiceMailMain(s${CALLERIDNUM})

Ringtones

http://www.cisco.com/en/US/products/sw/voicesw/ps2156/products_administration_guide_chapter09186a0080087511.html#1042487
The Cisco SIP IP phone ships with two ring types: Chirp1 and Chirp2. By
default, your ring type options will be those two choices. However,
using the RINGLIST.DAT file, you can customize the ring types that are
available to the Cisco SIP IP phone users.

Step 1
Create a pulse code modulation (PCM) file of the desired ring
types and store the PCM files in the root directory of your TFTP server.
PCM files must contain no header information and comply with the
following format guidelines:

8000 Hz sampling rate
8 bits per sample
ulaw compression
240 - 16080 samples long ( 0.03 sec - 2.01 sec )

For example, to use sox to generate the tones, use


Step 2
Using a ASCII editor, open the RINGLIST.DAT file and for each
of the ring types you are adding, specify the name as you want it to
display on the Ring Type menu, press Tab, and then specify the filename
of the ring type. For example, the format of a pointer in your
RINGLIST.DAT file should appear similar to the following:

Ring Type 1 ringer1.pcm

Step 3
After defining pointers for each of the ring types you are
adding, save your modifications and close the RINGLIST.DAT file.

Caveat:

If you have configured a secondary tftp-server(ie. dyn_tftp_addr : 192.168.1.10) in SIPDefault.cnf, or SIP<MACADDR>.cnf which cannot be reached then the phone will not attempt to download the RINGLIST.DAT file.

Controlling ring tones from Asterisk

By setting the Asterisk variable ALERT_INFO before you call Dial, Asterisk will add ringer tone info to the SIP invite that is sent to the phone. Note that this only seems to work for the internal ringtones and not for any custom ringtones.

Asterisk version <1
 exten => 3010,1,SetVar(__ALERT_INFO=<Bellcore-dr1>) 

Assterisk 1.0 and 1.2
 exten => 3010,1,SetVar(_ALERT_INFO=<Bellcore-dr1>)

Asterisk 1.4
 exten => 3010,1,SIPAddHeader(Alert-Info: <Bellcore-dr1>)

Available ring tones by default

 Bellcore-BusyVerify 
 Bellcore-Stutter 
 Bellcore-MsgWaiting 
 Bellcore-dr1  
 Bellcore-dr2 
 Bellcore-dr3 
 Bellcore-dr4 
 Bellcore-dr5

DialPlan Notes (DIALPLAN.XML)

The DIALPLAN.XML file controls the phone's matching of digits. By default "*" matches anything and times out after 5 seconds. Users must push 'Dial' or '#' to connect if they don't want to wait 5 seconds. For a variety of reasons, not least of which being that most phone users are not accustomed to pressing 'Dial' on their offices, it may be desirable to configure a dial plan for your organization.

If you wish to use the hash (by default it will immediately dial the number entered) include it explicitly as part of a pattern in DIALPLAN.XML
   <DIALTEMPLATE>
       <TEMPLATE MATCH="#..." Timeout="5" User="Phone" />
       <TEMPLATE MATCH="*" Timeout="5" User="Phone" />
   </DIALTEMPLATE>

In another example, we immediately match 9+10digits or 9+1+10digits, and match 5+2digits as internal extensions
  <DIALTEMPLATE>
     <TEMPLATE MATCH="5.." TIMEOUT="0"/>
     <TEMPLATE MATCH="9,1.........." TIMEOUT="0" Tone="Bellcore-Alerting"/>
     <TEMPLATE MATCH="9,.........." TIMEOUT="0"/>
  </DIALTEMPLATE>

In the above example, a secondary dial tone is invoked by the comma character. If the Tone attribute is left blank, the default will be used. Or you can specify one of the following:

• Bellcore-Alerting
• Bellcore-Busy
• Bellcore-BusyVerify
• Bellcore-CallWaiting
• Bellcore-Confirmation
• Bellcore-dr1
• Bellcore-dr2
• Bellcore-dr3
• Bellcore-dr4
• Bellcore-dr5
• Bellcore-dr6
• Bellcore-Hold
• Bellcore-Inside
• Bellcore-None
• Bellcore-Outside (default)
• Bellcore-Permanent
• Bellcore-Reminder
• Bellcore-Reorder
• Bellcore-Stutter

• CallWaiting-2
• CallWaiting-3
• CallWaiting-4

• Cisco-BeepBonk

Notes: This file is case sensitive in some firmware versions; all elements and attributes should be uppercase (except Tone) or the entries may be ignored. According to Cisco, the phone will always match the LONGEST expression.

Call Waiting Feature

The 79XX series phones have a good way of handling SIP registrations provided the Call Waiting feature isn't turned off. Most other SIP phones require an individual SIP username and password for each line appearance. Instead, the 79XX will automatically roll-over to the next available line. So, for example, on a 7960 you can have all six lines programmed to the same SIP username/password and the phone will automatically handle the call waiting function. Note: If you use any other method of ringing multiple lines on the phone (i.e. dialing SIP/123&SIP/456) your phone will show a confusingly high number of missed calls.

Troubleshooting Phone Registration

From the asterisk command line, execute "sip show peers" and "sip show users" to display the current status of the Cisco phone. If no entries appear in the list for this phone, then review the "username=3014" and "secret=mypassword" in sip.conf to ensure they match the entries programmed into the Cisco phone.

Troubleshooting Cisco Phone

The Cisco 79XX phones support telnet. (Enable telnet_level: 2 in the config) To diagnose problems with the Company Directory function noted above (as an example), telnet to the phone's IP address using the login password provided in the SIP00036BAAD139.cnf file noted above. For example, to diagnose a possible http problem, do the following:

Troubleshooting Cisco Phone Configuration issues.

• Any configuration parse error warnings are shown in the phone menu (Settings - Status - Status messages). Or from the telnet CLI, you can type "show status"

• Check the file that it reports a problem with. Check the permissions on the TFTP server that it can read the file.

• Carefully check the config file for obvious errors (missing speechmarks, spurious spaces etc.)

If you still cannot locate the problem, you can do the following to erase the phone config and debug it when it loads it back in again:
(Unfortunately this will delete any speed dial keys configured on the handset, and also auto answer setting as these cannot be put back again via TFTP.)
