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.

Subject: [SR-Users] Problem with selection Transport Protocol - MultiHomed
Problem
Hello ,
i have trouble about selection transport protocol. i have tried so many thing
but couldnt find TM selected which IPv? and protocol type (TCP or UDP)
For example;
i have 2 interface ipv6 and ipv4. i will route my message (INVITE-Register
etc.) another node that use TCP and IPV6 , domain name is test1.test. 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:a...@test1.test
Conclusion : There isn't any pseudo value about which destination of IP version
will use.
Thanks
