Re: [reSIProcate-users] Stack dropping response
This INVITE request is formed using the old SIP RFC2543 (ie. no branch
parameter in Via header), your other UA's are likely using RFC3261. I
suspect that somewhere down the line, DUM is calling getTransactionId
on the response that it's forming, and this is causing the error. It
would be useful to see a full INFO level resip trace of issue.
