Re: [SR-Users] Call drops after 1 minute

Hello, as you’ve guessed, this can be a common problem related to the routing of the ACK message. Have a look e.g. with ngrep or sngrep to the SIP signalisation on the server side and check if everything is correct in the SIP messages.

I have a CentOS setup in AWS where all my calls are dropped after about a minute or so. I realize this typically is a NAT problem, but I can't see where my error is. Sound is fine both ways. Kamailio is set with WITH_NAT and I use rtpproxy like this: OPTIONS="-l 10.1.2.10 -s udp:127.0.0.1:7722<http://127.0.0.1:7722> -d INFO:LOG_LOCAL5 -m 35010 -M 35110 -A 54.171.168.48" (10.1.2.10 is the local IP for CentOS) Tested with MicroSIP and Linphone and tried numerous configurations. It seems the receiving client is not able to verify the call has been set up, and disconnects. MicroSIP has the status "Connecting..." until it disconnects. All tips appreciated. Will post configuration and logs if needed. Kamailio version 5.6.2 from rpm and rtpproxy 2.1.0 compiled from source. -- Regards Christian B. Wiik
