Hi all, i'm newbie in SER,
I want to route RTP packets between 2
computers with x-lite client voip
in the same network through
Mediaproxy. I know this may have
no sense, but it's just a test
configuration.
The call use_media_proxy() seems to have no effect,
the
RTP packets go directly from one computer to
another, no packet trough
Mediaproxy.
This is my environment:
SER and Mediaproxy on the same PC
(192.168.123.186)
X-lite client_A running on 192.168.123.10
X-lite
client_B running on 192.168.123.168
Client_A call Client_B that accept,
but mediaproxy refuses to
proxy the call.
This is my ser.cfg

Is mediaproxy

Please help me. Any suggestions?
