[Users] force_rtp_proxy() problem.

[Bogdan-Andrei Iancu]

Hi Ray,

for bridging between two non-routable networks, you have an example 
about how to configure nathelper and rtpproxy :
    sip-server/modules/nathelper/examples/alg.cfg
(IMPORTANT: in the script header there is a note about how to start 
rtpptroxy in bridging mode)

you might find it very useful.

regards,
Bogdan
