[Asterisk-Users] quadBRI

[Tim Mickelson]

   Hi.

   We have a quadBRI card installed on asterisk 1.0, all is working 
fine,  incomming, outgoing calls, all works well.
   The disaster is, that if no one uses the card for some 2-3 hours, the 
card seems to change it's status. If I try to make an outgoing call, 
Asterisk registers that I'm trying to dial app, but in my sip phone from 
which I'm calling, I hear nothing, only some very weak clicking sound, 
and the phone I'm calling does not ring.
   If I make the call ingoing instead, the sip phone rings, when I 
answer Asterisk registers a bridged call, but the phone I'm calling from 
keeps on ringing.
   Does anyone recognize these strange behaviours?
