[Asterisk-Users] tdm04b hangup problem

[stevanus]

Hi,

I have severe problem here..
My asterisk server use tdm04b from digium and is often incapable of 
detecting hangup signal.
It is happened occasionally in  incoming call so I have to watch fop all 
the time and hangup the channel manually there.

Another problem is when an outgoing call was placed and the caller ended 
the conversation, the tdm04b did not hangup the channel. So when the 
caller does off hook too fast and interpreted by asterisk as hold, both 
zap channel will be connected by asterisk as the caller hangup the 
second call.

Anyone experiences this issue?
Is it possible that this is caused by improper setting in rxgain or txgain?
Currently, I set rxgain = 15.0 and txgain = 5.0..

Thanks..

Best Regards,

Stevanus
