[SR-Users] kamailio asterisk

Hello Everyone, 
I have standard case where kamailio play role of proxy for asterisk servers. 
Kamailio configured use TLS transport on public side and on private side UDP 5060. 
When client (SIP soft phone) connect to TLS socket everything goes well until kamailio trying forward request. Kamailio tries DNS resolve tls transport srv records instead of udp then it just crashed when no tls configured on private side of kamailio. 

Do I need manually fix sips in URI ? Or some different miss configuration ?
