UPDATE - I fianlly figured out why the UC520 has trouble with Packet8. Packet8 does not send the phone number in the INVITE URI. They are not RFC-compliant. Not that I can really complaint to them. I have been looking at debugs and packet captures for weeks now and missed it the entire time. See below...

Hello,

I have finally got my UC520 configured more or less how I want with one giant, glaring exception. I can NOT get it to receive incoming calls from my SIP provider. I am sip registered and I can see (via debug) the SIP messages come in during an incoming call. Outbound calls work fine.

I would like it to at least ring on my desk (ext. 201) as well as all phones (inc. analog) via hunt-group 1 (parallel).

I have tried CCA and CLI based configs. I have also tried as best as I could to read all the documentation on Cisco.com before I posted asking for help. I have hosed my config so many times that the box spends more time reloading than running :) I've also had to go back to factory defaults several times. So please know that I have tried everything I know of.

One item to note is that my SIP provider is Packet8. They in no way support the UC520 and in fact do not want anyone using their residential service with anything other than their cheap ATA. The reason I note this is because the debug shows:

SIP/2.0 400 Bad Request - 'Malformed/Missing URL'

Which may (or not) be part of my inbound call problem. I'm not running a call center here, I just want to tinker. Also, my SIP username is different than my phone number.

DEBUG INFO:

Note: this forum strips out the f: and t: header because it thinks it is html. I've replaced the greater than/less than symbols with brackets.

The UC520 doesn't like that:

So, other than dumping Packet8, does anyone have any suggestions for how to get the UC520 to ignore the fact that the INVITE URI doesn't have the dialed number in it? Freebie X-Lite can handle this.
