Limited CPU means limited compression

If you want to use a compressed codec to save on bandwidth (G.726 or G.729) the SPA-2000 doesn't have enough computing power to compress two phone calls at the same time. So you are limited to one compressed call and one uncompressed (G.711 codec) at the same time. The improved SPA-2002 does not have this limitation.

To upgrade the firmware via tftp

• put the spa.bin file in your tftp server directory
• on the Sipura provision page set "Upgrade enable" to "yes"
• using a browser on the tftp server - http://sipura-ip-address/upgrade?/pathname/spa.bin
• for example: http://192.168.2.10/upgrade?/tftpboot/spa.bin
• the Sipura will display a page explaining that the upgrade is in progress

Distinctive rings

• Set variable ALERT_INFO to change the ring cadences that Asterisk asks the SPA-2000 to play. Example:

• exten => 5555,1,SetVar(_ALERT_INFO=Bellcore-r7) ; possible values are Bellcore-r1 to Bellcore-r8
• exten => 5555,2,Dial(Sip/5555)

Be careful of the spelling of Bellcore-rX. It took me two hours before I realized I had written Bellcore-dr3 instead of Bellcore-r3.

Custom Ring Cadences

You can customise the ring cadences in the regional menu of your SPA-2000. For example to produce rings for the UK these settings were created by David_W and posted at http://voxilla.com:

SPA2000 Review

Notes

The Linksys PAP2 and PAP2-NA are very similar products that contain Sipura written firmware.

• The PAP2-NA has the same processing power limitation as the SPA-2000 described above. It can only handle one compressed call at a time. If you want to make two calls then one of them must be uncompressed.
• The PAP2-NA can be purchased from DeployVoip!
