[Freeswitch-users] Grandstream ATA702 - dropped calls

[William Colls]

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.
