Have you checked a trace? What's the hangup reason? Calls getting dropped at 30 seconds usually means there's no 200 OK ACK. Get a trace and verify that, also check the RTP IPs.

When I make an outgoing call through this device, the call is often disconnected after about 30-40 seconds. Incoming calls are fine. I have SIP transport set to UDP, NAT Transversal set to NO, Enable SIP Options Keel Alive set to YES, SIP Options Keep Alive Interval set at 30, and SIP Options Keep Alive Max Lost at 3. Freeswitch version 1.10.1 was started with -nonat. Obviously I have missed, or miss-understood, something. Any pointers or suggestions will be most welcome.

Thanks for your time.

William.
