[Freeswitch-users] Register-transport and Register-Proxy with TCP

David,
If you read my original email you will see that I'm setting it this way.
For some reason, it sends out UDP although all the headers indicate that it
is sending with TCP.

Are you telling me that with this setting you are able to send traffic via
TCP ?
