Hello Friends, I believe that branch parameter is used to identify transaction until dialog is created. Once dialog is created callid, from-tag and to-tag is used to identify the dialog.
branch param is mainly used by proxies to identify transactions in case of parallel forking. I can't understand why a UAC(phone) will need to send branch parameter in first originating request. Please throw some light. Best Regards, Manish Jain __________________________________________________ Do You Yahoo!? Tired of spam? Yahoo!
