Hi kasam The Via header value of the response MUST match the Via header of the request.
Regards Ranjit -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Kasam Patil Sent: Tuesday, August 10, 2004 8:00 AM To: [EMAIL PROTECTED] Subject: [Sip-implementors] Via Header in Response Hi, Is it a MUST to have the Via header in the response be exactly the same as in response ? For example, take a look at the PRACK and 200 OK exchange (seen below). Is the 200 OK response acceptable ?
