CME, SIP-UA, IOS upgrade problem.

Hi.

There is a 2811 ISR router with CME 7.0 onboard.

It has SIP-UA based trunk to service provider.

It has 12.4T IOS and all working fine. Since we need to add support for 6921 phones i have upgraded it with 15.1 IOS.

I turned "Toll fraud prevent" feature off.

But sip-ua trunk stopped working. I've debugged with debug ccsip messages, but it seems that they are identical, but appears like remote party do not receive our TRYING and RINGING messages and keep spamming with INVITEs.

Problems with inbound calls only.

Configs almost identical except for tftp-bindings and toll fraud commands.

Here is SIP log from 12.4T:

I can't tell any difference in initial replys, but in latter case it seems like remote party does not receive any of them.

Pinging remote party IPs, telnetting them to 5060 ports works without any problem.

Don't know what to do..

Here is cut down config:

Hey good stuff.

Where did you get the via-port part? Just from cli or did you find some more info on connection-reuse command?

Cheers,

Tim

Saw in some cross-platform release notes while searching for "conenction-reuse". "connection-reuse" alone did not help. It was also in CLI help, so i tried it.
