Hi,

I modified the configuration in my openser.cfg and now is possible hear audio in 1 direction (I hear the other people).

Interesting is that the logs shows that rtpproxy “has been disabled temporarily”.

openser.cfg:

#modparam("nathelper", "rtpproxy_sock", "unix:/var/run/rtpproxy.sock") # Nathelper with RTPproxy
modparam("nathelper", "rtpproxy_sock", "udp:xxx.xxx.xxx.xxx:8899")

service run:

root 13256 0.0 0.0 2536 344 ? Ss 13:13 0:00 /usr/bin/rtpproxy -l xxx.xxx.xxx.xxx -s udp:xxx.xxx.xxx.xxx 8899

logs:

Sep 10 13:19:50 src@sip2 /usr/sbin/openser[15433]: ERROR: send_rtpp_command: can't send command to a RTP proxy
Sep 10 13:19:50 src@sip2 /usr/sbin/openser[15433]: send_rtpp_command(): proxy <udp:xxx.xxx.xxx.xxx:8899> does not responding, disable it

Sep 10 13:19:50 src@sip2 /usr/sbin/openser[15433]: WARNING: rtpp_test: support for RTP proxy <udp:xxx.xxx.xxx.xxx:8899>has been disabled temporarily

Some tip ?

Regards

Jeferson

Subject: [OpenSER-Users] Problem with rtpproxy

Hi Guys,

When I originate a call for an user behind of a NAT the call is without audio in the two ways.

I believe that the problem is related to rtpproxy, however did not find nothing of wrong in my configuration.

Some tip?

openser.cfg:
# ------------- !! Nathelper

modparam("registrar", "nat_flag", 6)
modparam("nathelper", "natping_interval", 30) # Ping interval 30 s
modparam("nathelper", "ping_nated_only", 1)   # Ping only clients behind NAT
modparam("nathelper", "rtpproxy_sock", "unix:/var/run/rtpproxy.sock")   # Nathelper with RTPproxy

service run:

ps -aux | grep rtp

root 26098 0.0 0.0   2532   428 ?  Ss   10:40   0:00 /usr/bin/rtpproxy
root 11143 0.0 0.0   2536   352 ?  Ss   11:30   0:00 /usr/bin/rtpproxy -l xxx.xxx.xxx.xxx -s udp:xxx.xxx.xxx.xxx 7890

logs:

Sep 10 11:32:59 src@sip2 /usr/sbin/openser[11859]: rtpp_test: RTP proxy <unix:/var/run/rtpproxy.sock> found, support for it enabled
