I'm not surprised that the 7940 worked. The 7912 (with the latest firmware) also works fine with Axon. Unfortunately the newer 7960 and 7970 uses XML configurations that can only be loaded by TFTP and also close off the requesting port immediately as shown in the packet trace. Very annoying! I don't think there's anything I can do about it unless Cisco offers a patch. So, I wouldn't be surprised if other people begin to have the same problems with these annoying Cisco phones when used with Axon.

Hey, any action on this front? Is it a bug or just me? Meanwhile, I have got the phones working on Asterix for Windows so I know it's not a problem with the phones.

There might be a bug in Axon PBX (or with Cisco IP phones!). Cisco 7970 and Cisco 7960 phones send their SIP Registration request from random ports, but I think they expect the response on the "Contact" port. See below for a WireShark capture of three packets (Register > Authentication required > Port unreachable). What do you think?
