[Asterisk-Dev] Dropped Cell Calls

[kurtz]

I'm using a port on a digium 4-port card to interface to a T1-PRI.
It seems as if when cell calls are made to the PRI they are dropped shortly
(10-15 secs) after connecting.
Can anyone give me an idea of where to start troubleshooting this issue ?
It's almost like they go out of range and the PBX figures they've hung up or
something.

Don't really know where to grab on.  My dialplan is basically...

1112223333 = assigned DID (these DID's are switched down the PRI to my card)
4445556666 = these are alternate numbers.. like cell phones.. other PSTN
lines...

exten => 1112223333,1,Dial(Zap/g1/4445556666,25)
exten => 1112223333,2, Hangup
