Re: [SR-Users] Problem with selection Transport Protocol - MultiHomed Problem

Hello; i want to force message to send over TCP and IPv6 . so it should be R/W variable. When i set $fs or force_send_socket() it gives error about mismatch protocol ! Thanks.

TM module or some module resolve this domain to IPV6:UDP  but i want to sent it over IPV6:TCP socket.  so i cannot know which protocol is resolved and cannot route the right socket.  $du variable show only sip:ali@test1.test  Conclusion : There isn't any pseudo value about which _destination of IP version_  will use.
