[asterisk-users] asterisk / sipura call breaking up on silence?!

[R_O_L_A_N_D at hotmail.com]

Hi All,

I'm facing a problem that's occurring more often..

my setup is as such :

PSTN- Sipura 3102- Asterisk- siphones.


whenever a call takes place both outbound as well as inbound, if there were 
a bit of silence, the channel gets closed.
if there were a bit of latency, the system detects it as silence, and it 
closes as well..

any advice?!
