DisconnectOnBrokenConnection

Go under Protocol Management -->Advanced Parameters-->General Parameters and either
a. Disable Disconnect on Broken Connection
or
b. Increase the value of Broken Connection Timeout

If you took an ethereal/wireshark packet trace, you will see that the UM server stops sending RTP 10 seconds before the disconnect.  Usually because it doesn't have anything else to play out.   

To handle this please use the above settings.  Disabling the Disconnect feature shouldn't be a problem, as it is expected that the PSTN side will terminate the call.

DisconnectOnBrokenConnection=0
BrokenConnectionEventTimeout=60000

Thanks

audiocodes RestoreFactorySettings

By the way, there's an easy way resetnut gateway to default settings without having to hand the configuration file.

Start the Explorer, in the address bar write http://xxx.xxx.xxx.xxx/CmdShellInterface
xxx-gateway

In the window that appears:
1. CONF <enter>
2. RestoreFactorySettings <enter> (you can briefly RFS)
3. SaveAndReset <enter> (you can briefly SAR)

The same can be done by connecting to com-port, and via Telnet interface, which must first be activated. By default, Telnet is disabled.

P.S. Gateway IP address when this does not reset izmenyaetsya.dslepnev
