Ok, here it goes again.
Pay attention to the "200: OK" response from the PSTN-GW. I think
its Contact
header should be read by the Cisco GW (calling party), and then send
its
ACK-request with R-URI based on that Contact. But it doesn't happen.
Then here i
think this is the failure. (rfc3261, section 12.1.1 and 12.2.1.2).
May i am wrong..
What do you think?
I'd appreciate your comments
I agree with your assessment. The target request URI of the ACK
generates by the Cisco UAC should be the Contact URI received in the
200 OK.
I work with Cisco ISDN-VoIP gear all the time and have never seen a
device do that, though. It is either a very unusual bug in a very old
IOS release or a misconfiguration.
Can you tell me what device and IOS version is involved? Also,
applicable elements of the running-config could help.
Cheers,
