BIG-IP SIP profile MR does not maintain the Via 'branch parameter' ID when the Via header insertion is enabled for INVITE and CANCEL for the same INVITE.
The result is different branch IDs for the BIG-IP system-generated Via header. INVITE is only cancelled on the calling side, while on the called side, the line will ring until time out.
This happens only when the following conditions are both met: -- The transport connection that issued INVITE has been terminated. -- A new transport is used to issue CANCEL
None.
The branch parameter value calculation now remains consistent throughout the connection.
