[OpenSER-Users] Help Sending calls to PSTN

[Ali Jawad]

Hi there my config file is 

http://pastebin.com/d33669ee8

 

I have set 

modparam("nathelper", "ping_nated_only", 1) 

modparam("registrar", "nat_flag", 6)

 

This gives me the following error:

 

Jan 31 16:47:26 [16380] ERROR:core:set_mod_param_regex: parameter
<nat_flag> not found in module <registrar>

Jan 31 16:47:26 [16380] CRITICAL:core:yyerror: parse error in config
file, line 173, column 19-20: Can't set module parameter

 

If I set 

modparam("nathelper", "ping_nated_only", 0) 

and ### modparam("registrar", "nat_flag", 6)

 

This allows me to run openser but when I make a call to PSTN the
following warning is sent out

Jan 31 16:55:45 [16484] ERROR:nathelper:send_rtpp_command: can't connect
to RTP proxy

Jan 31 16:55:45 [16484] ERROR:nathelper:send_rtpp_command: proxy
</var/run/rtpproxy.sock> does not respond, disable it

Jan 31 16:55:45 [16484] WARNING:nathelper:rtpp_test: can't get version
of the RTP proxy

Jan 31 16:55:45 [16484] WARNING:nathelper:rtpp_test: support for RTP
proxy </var/run/rtpproxy.sock> has been disabled temporarily

 

Calls between softphones work but a call to the PSTN ends up with the
following

 

Jan 31 16:57:26 [16509] DBG:core:grep_sock_info: checking if port 5060

If I use tcpdump I don't see any traffic leaving for my PSTN GW.
