RE: Unable to register phone on Zultys MX250 r8.0.3: SIP 400 Error
I am curious, At first glance it looks like only the User-Agent field had changed between the versions. Can you give some release notes or is this a test build?
After a second to test the phone I found a problem. When dialing out the call would get to 100 Trying back from the pbx but then it would timeout. If this helps I have included a pcap of the call flow below.
From my past experience I tinkered a bit and changed two settings. First I changed the Local SIP port on Account1 to use 5060 (I have seen this with other SIP phones cause problems). Second I removed the G722 from the codec list on Account1. The Zultys doesn't support g722 natively. After that I was able to successfully place a call.
Even though the use of a port other than 5060 on the phone is legal according to RFCs. I have seen this cause problems on many other systems and routers with SIP-ALG. Can you set the default to port 5060 for all accounts (the current is 5062).
Also can you remove g722 from the default codec list. As most of the PBXs I have seen do not support that codec natively. I think if you are limiting the default codec list. The list should only contain g711 a/u only. I know this should work if you offer a list the to ends should just negotiate the list. I blame Zultys for this one but have seen the same behavior on other pbx systems.
Thanks,
Isaac
