Getting "SIP/2.0 503 Cannot Create Transport Connection"
Hi there
We have a 9200 SBC, that is sending back "SIP/2.0 503 Cannot Create Transport Connection"
In response to a INVITE (re-invite for a 30 min call in progress)
And then the call fails
I don't know what this is telling me.
Has anyone experience this before?
Or can anyone explain why the 9200 is sending this?
Or suggest logs, other items I could check?
Gary
