Hello Alex

Contact: <sip:user_7u9bbhcwxz at 96.231.222.110:52303
;transport=tcp>;+sip.instance="<urn:uuid:64862a3d-4380-4e21-89db-9e718493a4b1>"


RURI header from FreeSwitch 1.6.20 ACK

Request-Line: ACK sip:user_7u9bbhcwxz at 96.231.222.110:52303;transport=tcp
SIP/2.0

important to loos route message?

Sergey
