What does this mean?

481 Call/Transaction Does Not Exist

I'm having some issues with external calls.

Is this a media negotiation problem?

Chris

I have this problem too.

We need the entire SIP dialog to know what's going on. Generically speaking 481 means that the Call-ID isn't valid.

Please remember to rate helpful responses and identify helpful or correct answers.

Hi Chris,

some more verbose info, (like Johnatan also mentioned)  would be helpful.

Also include some info about your setup, involved components, call flow, ....

In a VCS enviroment I had seen it when there were firewall/alg/nat helper which messed

with the call or anything else dropping or tempering sip messages.
