Hey!
This is my first time posting to the list, although I'm a long time reader :)
I have searched the archives as well as the internet and found no solution or answer to this so far. Perhaps my Google Kung Fu isn't what it should be.
Anyhow, I have a cisco 7905 phone working together with a SER machine. When dialing to the 7905 phone from another phone and hanging up on the caller phone before answering the 7905, ie CANCEL before the call has actually been setup, I get a "SIP/2.0 481 Call Leg/Transaction Does Not Exist." back from the Cisco phone.
It's a pretty basic configuration (basically the one used in the examples for call forwarding). What I want to know is how the phone identifies a Call Leg/Transaction. I have used ngrep quite extensively and found nothing. Most values in both the INVITE and CANCEL message are equal.
I've also got a Thomson ATA box which does not show the same behaviour despite being connected to the same SER.
What values are used to identify a transaction, how can I see if two messages are of the same transaction?
Perhaps this is actually a user agent problem, but I don't really know where to turn for help with this 7905 (Cisco only provides support if you use their Call Manager solution).
regards, Kristian.
Hi Kristian,
"Hur er leget?"
Related to your problem, I think you might be running a little old version of the Software on your 7905. Try to upgrade to latest software on it. I know that on cisco 7960 there was this problem some time back that they changed the callid or something stupid.

I'm running CP8905080000SIP060111A, or at least that's what is says under firmware version in the phone. I believe it's quite new.. any ideas? Perhaps a downgrade? Anyone else with a 7905 running some "stable" firmware?
Kristian.
