[OpenSIPS-Users] OpenSIPS cannot connect to "mediaproxy/dispatcher.sock"

[Pasan Meemaduma]

Hi Steven,

Are you sure your dispatcher and relay daemons are running ?
use "ps aux | grep media" and see if they are actually running as background processes

btw look of it your dispatcher doesn't seems to be running. if it was, it'll create the socket file given in the config.

 Greetings, 
I am having difficulty getting OpensSIPS to connect to MediaProxy for the purpose of bridging media of clients behind NAT, and hope the community has advice on how to resolve. 
I have installed MediaProxy from the Debian Jessie repository, and updated the config.ini file to disable TLS, Radius, etc - and set the dispatcher and relay IP to the public IP of my opensips server. I have mediaproxy and opensips installed to the same server with a direct public IP. 
Currently, it looks as though opensips correctly detects the client is behind NAT and tried to invoke mediaproxy. The calls seem to fail when opensips goes to connect to mediaproxy using the designated socket. Although mediaproxy service is running - it does not create the socket. 
Opensips version = 2.3.5

/etc/init.d/mediaproxy-relay and mediaproxy-dispatcher start does not give any error, and returns OK status for MediaProxy. 
The opensips module config for MediaProxy is: 
#### Media Proxy moduleloadmodule "mediaproxy.so"modparam("mediaproxy", "mediaproxy_socket", "/var/run/mediaproxy/dispatcher.sock")modparam("mediaproxy", "mediaproxy_timeout", 500)modparam("mediaproxy", "signaling_ip_avp", "$avp(nat_ip)")modparam("mediaproxy", "media_relay_avp", "$avp(media_relay)")modparam("mediaproxy", "ice_candidate", "low-priority")modparam("mediaproxy", "ice_candidate_avp", "$avp(ice_candidate)")
The MediaProxy config.ini set the socket to this as well: 
[Dispatcher]; Local socket on which to communicate with OpenSIPS. The OpenSIPS mediaproxy; module should be configured to connect to this socket. If a relative path,; /var/run/mediaproxy will be prepended. Default value is dispatcher.sock.;socket_path = dispatcher.sock
Any advice for this would be much appreciated. I have tried to resolve and find configuration examples for a few hours now. _______________________________________________
