<DIV>Just as an extra : I have a sniff of the message for when a public client (2092)rings a private client (2093)included at the bottom of this email.

<DIV>I changed the line modparam("nathelper", "rtpproxy_sock", "/var/run/rtpproxy.sock") to modparam("nathelper", "rtpproxy_sock", "udp:localhost:22222") and started the rtpproxy as ./rtpproxy -s udp from the relevant directory and this resulted in a series of "rtpp_command: no response from rtpproxy" and rtpproxy temporarily disabled" errors. If I return to the original modparam and start it as ./rtpproxy then it works but like I said when the private client rings the public client, I get "ERROR: send_rtpp_command: cant read reply from a RTP Proxy".</DIV>
<DIV> </DIV>
<DIV>Any further ideas? Has anyone on the mailing list experienced this? I am using the script given in the onsip getting started doc for 0.9.0. but am using ser 0.8.14.</DIV>

<DIV><BR>> Thank you for that Greger. I have altered my script so that it<BR>> exactly mimics the one in the onsip document besides the has_totag<BR>> and fix_nated register.

Is this correct? <BR></DIV>
<DIV>That's correct. You will find code in the example configs where we test for an empty body before calling force_rtp_proxy.</DIV>
<DIV><BR>> However when I try to phone from public into private I get:<BR>> <BR>> ERROR: send_rtpp_command: cant read reply from a RTP Proxy.<BR>> <BR>> I find this confusing because I know the rtpproxy is working.<BR></DIV>
<DIV>This means that rtpproxy is not responding to a particular message. I have heard some people have had problems with the socket based communication. I only use UDP. This is what you do to set up udp (22222 is default port):</DIV>
<DIV>modparam("nathelper", "rtpproxy_sock", "udp:localhost:22222")</DIV>
<DIV>rtpproxy must be started with -s udp:*</DIV>
