[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.
