Making Cisco 7945G work with Asterisk again after firmware update from v.8 to v.9

24 09 2012

After SIP firmware update to version 9.3 on my Cisco 7945G and 7965G phones they all stopped to register with Asterisk. They did load config from tftp and then just stayed with “Registering” on screens forever.
What caused it is dropped UDP support in new version of SIP firmware and one required update to SEP{MAC}.xml config files, so, make following changes and may the force be with you:

sip.conf:
tcpenable=yes

SEP{MAC}.xml  (in each <line button=”N”> section):

<proxy>USECALLMANAGER</proxy>

Thanks. Are you seeing issues with conference features? We get unavailable with the 7945G using basically the same config from a 7941G in both 8.x and 9.x firmware (all other features seem to work).

Conferencing works same as before update on our side, instead we have another unresolved issue – CFWD button doesn’t work anymore.
