Hello,

you can add ";transport=..." to $ru if there is something wrong on how the UA builds the contact or r-uri:

$ru = $ru + "...";

Cheers,
Daniel

Hi. Have strange issue

Calling from kamailio through WS

invite and resposes goes ok but with ACK to WS client has this issue

 get_send_socket2(): protocol/port mismatch (forced tls:kamailioIP:4443, to udp:MyWSClientIP:65451)

Guess kamailio thinks that it is UDP client because 
$ru is sip:10002@MyWSClientIP:65451

But can not understand how to fix this...
