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:ali@test1.test
Conclusion : There isn't any pseudo value about which destination of IP version will
use.
Thanks
