What does this mean?

481 Call/Transaction Does Not Exist

I'm having some issues with external calls.

Is this a media negotiation problem?


I have this problem too.

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.
