Cisco 7940/7960

Support for the configuration of these devices is limited to this article. 

79x0 series phones have been "end of life" since 2010. Their replacement 79x2 models also reached "end of life" in 2015. These phones were designed for closed office telephony environments with a local PBX or phone system. 

The phones don't support STUN. If your router supports SIP ALG check that this setting is disabled. 

Try using this configuration as a guide. A customer has provided these details using firmware version 8.2. Your phone must have the SIP firmware version loaded. 

If you're purchasing new phones sipgate recommends using SIP devices with ongoing manufacturer support and updates, in particular from deskphone manufacturers like Snom, Gigaset, Grandstream and Yealink

You'll find your SIPID and SIP Password in your sipgate team account
