Cisco 7960 (SIP firmware 8.12) behind NAT 26.05.2012 22:18

Forum: Terminal Equipment

I have a large number of Cisco 7960 phones with SIP firmware 8.12 (P0S3-8-12-00) which I would like to use with a premium PBXes account. They are located in branch offices behind NAT gateways.

Has anyone made this work?

This may be the same issue:
