[OpenSIPS-Users] install rtpproxy on same host or diff host - bridge mode or not ?

[mani sivaraman]

It works now. The problem was in my fix_nated_coontacts() calling location

flow after the call is connected. the delay is some times 8 to 10 sec.
force_rtp_proxy() works even though it is deprecated.
