Hi All


I am having a tinker trying to get a Cisco 7960 to work with 2 talk


My setup:


ERL lite


Cisco 7960 P0S3-8-12-00 firmware


I have a cisco SPA112 already working with the 2talk logon details and also have got the Cisco 7960 able to register and working with another voip provider (


Once I got this working, all I did then was update the 2talk sip address, username and password etc to the config files


I dont think its firewall or NAT??? and I've check auth name and password for incorrect typos,




I turned on debugging and compare the logs to the successful logon vs unsuccessful




This is the diffs in the unsuccesful




[15:09:08:103370] SIPProcessUDPMessage: recv UDP message from <>:<50195>, length=<471>, message=

As I recall, these handsets default to 'SIP Skinny', which was Cisco's proprietary enhancement that meant the handsets only work with a Call Manager.




To run with a 3rd party service like 2T, you need to load a SIP Standard firmware on the device. Is that what your device has?
