[OpenSIPS-Users] OpenSIPS Retain Protocol on relay

[duane.larson at gmail.com]

I did a search for "tcp" on Nabble's OpenSIPS section and just found this

http://opensips-open-sip-server.1449251.n2.nabble.com/How-to-change-transport-protocol-of-R-URI-td6376471.html

I would say you need to use t_relay() with parameters.

Hope that helps.
