Been working on migrating over to Asterisk 13 / FPBX 12, and wanting to control my Cisco endpoints with OSS EPM. Starting with the phones that have support out of the box - the Cisco 7940.
Using a PJSIP extension, I can confirm that the extensions are working via a softphone. When I fire up the Cisco 7940 it has trouble registering. Watching a tcpdump I can see…
Phone sends a REGISTER with no auth details (as normal)
Asterisk replies with 401 UNAUTHORIZED (the REGSITER challenge, normal again)
Then nothing … couple seconds later, the phone sends another REGISTER, with no auth details.
Wondering why these endpoints don’t reply to the 401 with a REGISTER that contains auth details? Is this a firmware thing (using SIP 8.12 that came in OSS EPM)? Is it a configuration thing? Is it a PJSIP thing (I’m having issues serving a config with different ports for one reason or another)?
Would really appreciate anyone’s input if they’ve had this problem before. Our other system, Asterisk 11 doesn’t have this problem. Although, I do all the configs manually on that system, and the only other difference is chan_sip instead of PJSIP.
