7960 won't register

Hi all,

I'm having a bit of a problem with two of my new phones. I'm wanting to connect 3 phones behind a nat to pbxes. The siemens s450ip connects without any problems. However the sip cisco 7960 phones just won't register. I have tried everything to my knowledge; turned nat on the phones on, used a different pbxes server on each phone, using different ports. All 3 phones are able to connect to a Voipcheap account and make phonecalls. Even when the siemens phone that does connect is removed from the network, the cisco phones still won't register, they never have!

I'd appreciate any suggestions!

From what you describe, I believe the Cisco phones are highly unlikely to function properly. This thread will provide you with additional information:
