Srbislav and all,

Hi, Thanks again....I added these commands and still got the same results. Here is a debug im getting from the gateway. The first line is concerning ??? What would be sending an invalid method? Could this be coming from the end device? I also added a snip of ngrep and as you see the ack is not being accepted... any ideas?

64.72.107.2 = gateway 10.0.0.222 = ser 10.0.0.35 = host

Is your call being dropped as well?

I had the same issue with VEGA gateway. This is what I did to solve the problem. Change your ser.cfg file like this

if (uri=~"^sip:9[0-9]*@sip_server_ip") { ## This assumes that the caller is log("Forwarding to PSTN\n"); ## registered in our realm strip(1); #t_relay_to_udp( "gateway_ip", "5060" ); rewritehostport("gatway_ip:5060"); forward(uri:host, uri:port); break; };

t_relay_to_udp causes this error in the log and also the call to drop. Rewriting host and port works fine.

Hope this helps.

Hi,

Im connecting to a cisco gateway, and the call looks fine, until the SER has to send an ACK. to bring the status of the call to active.

When i look on my messages in the log, i am getting a message

Warning: sl_sed_reply: I wont send a reply for ACK!!!

what does this mean?
