Hello,

is there any naptr or srv dns record behind test1.test domain? Or just A/CNAME record?

Cheers,
Daniel

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
