[OpenSIPS-Users] OPTIONS over TCP

[Ali Pey]

You don't really need Options for TCP. You use Options to keep UDP
ports/connection open. TCP is a stateful connection. You only need to make
sure that opensips keeps the connection open for the period of the time it
is needed.

is_from_gw should work since it works based on the src_ip.
