Hey Steve, Can provide us a snippet of code on how you are populating the $ru and making invoking the relay?

Kamailio is now trying to send TCP but it is using the incorrect port. Kamailio is relaying to Asterisk on xx.xx.xx.xx:some-large-port but Asterisk is listening on xx.xx.xx.xx:5060. I’m not sure why this is happening. I would appreciate any help.
