Hi!

I have the following configuration:

---------------- ------------ ----------- | PSTN-Gateway |--------|1. 2.|-------| Clients | ---------------- ------------ ----------- | internet | local NAT

Ser 0.8.12 runs only on the 2. interface. My configuration is:

# ------------------------- request routing logic -------------------

# main routing logic

route{

if (!mf_process_maxfwd_header("10")) { log(1, " Too many hops!"); sl_send_reply("483","Too Many Hops"); break; };

if ( msg:len > max_len ) { log(1, " Message too big!"); sl_send_reply("513", "Message too big"); break; };

record_route();

if (uri==myself) { if (method=="REGISTER") { save("location"); break; };

if (!lookup("location")) { #if it is a call to PSTN then forwad it to the #gateway if (uri=~"sip:0+?[0-9]+@.*") { rewritehostport("152.66.244.200:5060"); force_rtp_proxy(); t_on_reply("1"); if (!t_relay()) { sl_reply_error(); }; break; }; sl_send_reply("404", "Not Found"); break; };

}; if (!t_relay()) { sl_reply_error(); }; }

onreply_route[1] { if (status=~"[12][0-9][0-9]") force_rtp_proxy(); } #---------------------------------------------------------------------

When initiating a call from the client to the PSTN I get the following error:

ERROR: extract_mediaip: no 'c=' in SDP

But when I watch the incoming INVITE packet with tcpdump, I can see the connection information.

Thx oli
