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..

Interesting!
I read that via only needs port if it is not default.
I didn't see anything on source ports except for this..
http://www.ietf.org/rfc/rfc3581.txt
That seems to say that with UDP, it is expected that you would reply to the Via port (in broadsoft case, not specified, so assuming 5060) - so it seems 12.4 would be in line with this.
Did you check bug toolkit? It seems like something that would appear. Or maybe as a changed behaviour in release notes?
There is the connection-reuse command. My understanding is this one should ensure the CUBE sends the replies from source port 5060. I cant find any docco about what it does to destination. I think this command is on in both your configs, as source is 5060. But it may also be interesting to see what wireshark says with this off.
i.e. if it wasn't re-using a connection, maybe it would just send the reply straight to 5060.
Sorry that probably doesn't really help too much.
Cheers,
Tim.
02-19-2013 02:07 PM
I would think you do need to have connection-reuse under sip-ua. I have a client with Broadworks who uses 2900 series with 15.2 with connection-reuse. (it didnt work without connection-reuse and invites were ignored by provider - similar to what you see)

On 15.1 I would try going connection-reuse - no connection-reuse - connection-reuse. If that doesnt help power cycle the router with connection-reuse on (make sure you got your config saved )

Hey mate,
I think if toll fraud prevention was the issue, you could see it kicking in by debugging ccapi voip inout
But you are receiving the INVITE from the far end, so I dont think that is the issue.
I've seen fragmentation problems with UDP
Your SIP message looks the same, so that shouldn't be the change
But perhaps the way IOS is handling the packet could be an issue
Exactly what IOS are you running?
Check out this article (search for IP CEF) and you will see a couple of recommendations.
https://supportforums.cisco.com/thread/2154873
I think in most of these cases it is a good idea to open a ticket with the carrier as well. Ask them to check their logs and see if they are receiving your messages (and responding)
External wireshark cap is always nice as well, if you havent tried this.
Cheers,
Tim

First it was c2800nm-adventerprisek9_ivs-mz.151-4.M4.bin
Next i tried c2800nm-adventerprisek9_ivs-mz.151-4.M5.bin
Used capture on router itself, there were packets generated by CPU at least.
But perhaps the way IOS is handling the packet could be an issueExactly what IOS are you running?

Hi, try this

allow-connections sip to h323

I did, also tried disabling at all, by the book.
Did not help. Also, router would not answer at first place.
02-17-2013 10:02 PM
I think I'd be tempted to just try the work around:
configure "no ip cef" in the router, see if it will help
configure " ip virtual-reassembly" on the interface which will have the incoming SIP INVITE
If that works you know it is a fragmentation problem.
I think in our case we upgraded to 15.2.1 T2.
Sorry I dont have bug ID or more details.
Cheers,
Tim.

I will, just need to wait people go home.

Playing with ip cef anf virtual reassembly did not hepl and actually was not the case.
After some wiresharking and swapping IOSes i've found the reason:
Here is message flow in 12.4T IOS:
Service Provider -> Our router
INVITE: UDP src port: random X dst port: 5060
Our Router->Service Provider
Trying: UDP src port: 5060 dst port: 5060
Ringing: UDP src port: 5060 dst port: 5060
Here is message flow in 15.1 IOS:
Service Provider -> Our router
INVITE: UDP src port: random X dst port: 5060
Our Router->Service Provider
Trying: UDP src port: 5060 dst port: X
Ringing: UDP src port: 5060 dst port: X
In 15.1 IOS, router uses the same socket for sending replies.
SP support team claims that their Boradworks device does not support this behavior and expects replies on 5060 port.
Is there an option to switch to old behavior in 15.1 IOS?
02-18-2013 08:27 PM
Another difference in behavior found:
Broadworks switch sends INVITE requests with VIA header without port:
INVITE sip:73952486173@172.24.4.14:5060 SIP/2.0
Via:SIP/2.0/UDP 172.30.252.1;branch=z9hG4bK-
Comparing with Cisco's INVITE:
INVITE sip:74113698212@irk.voice.dsi.ru:5060 SIP/2.0
Via: SIP/2.0/UDP 172.24.4.14:5060;branch=z9hG4bK18EA255C
there is port field.
Wich port should be used for sending 100 replies? Which IOS is more correct?
I was trying to read SIP RFC, but they are not specific on that case.

Do you propose to issue:

no connection-reuse
?
I tried searching Bug toolkit, but did not find anythig usefull.
02-19-2013 04:01 AM
playing with connection-reuse on 12.4T did not change anything, at least broadworks can see messages.

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?
