Adding support of Cisco 7931 to Chan_sccp

Version 2

In version 1 I can't add support of application, headset, messages and directory buttons - because I have no idea how to get type codes of this buttons. Also I have no CCM for research. But I find a message in chan-sccp-b-discussion email Archive, where Jasper Siepkes tells how to hacking chan_sccp for add this functionality and problems which he has with modified sources compiling. I'm modify my path for chan-sccp-b-20071213 release for adding support headset, application, directory, messages buttons. New path

chan_sccp-20071213-mod-cp7931-2.patch
In sccp.conf you need to add empty speeddials in 24, 23, 22 and 21 position.

Modification details
When I find the message, I can't download Jasper's path - sf.net tell me about error (now this problem is fixed) Therefore my modifications is little different. Also I fix problem with BUTTONTYPE constants in chan_sccp. SKINNY_BUTTONTYPE_MULTI, SCCP_BUTTONTYPE_LINE, SCCP_BUTTONTYPE_SPEEDDIAL, SCCP_BUTTONTYPE_HINT is made only for internal use in chan_sccp implementation. So I change their values from 0xc0-0xc3 range to 0xe0-0xe3. Modified chan-sccp-b work with asterisk 1.2

Thank Jasper Siepkes

Version 1

I have a Cisco 7931 IP phone and trying to connect them with Asterisk. Unfortunately there are no support of this device in chan_sccp. Maximum, that I could make - it use оne line for register device and making/receiving calls. I can't set speedials buttons, monitoring lines state... In hope to find the decision of a problem I was search internet resources. But I have found only the same problems at other people and any decision. Therefore I have decided to add support of Cisco 7931 in chan_sccp.

There are step-by-step instructions:
1. download chan_sccp sources from http://sourceforge.net/projects/chan-sccp-b/ I'm using chan-sccp-b-20071213 release
2. extract sources in folder
3. add CP7931 support - download and apply patch

chan_sccp-20071213-mod-cp7931.patch
4. compile chan_sccp
5. install new chan_sccp on Asterisk
6. configure: edit sccp.conf and extention.conf
7. in CLI run "unload chan_sccp.so" and "load chan_sccp.so" (reload seems does not really reload sccp.conf), and reload all configuration by running "reload"

sccp.conf
