asterisk users - Oct 2007 - E&M Wink and T4xxP losing ability to dial

Hey folks,

I'm pulling my hair out on this situation and would welcome some advice:

I'm using the AMI Manager to Originate calls onto 2 E&M wink T1 circuits
via
a T4XXP card from Digium.

Everything works fine for about 600(+/- 50) calls then the Manager is
suddenly unable to launch calls. Using ZapBarge to listen to the channels
themselves you can hear the dtmf digits being dialed, but then either there
is dialtone (again), or a fast busy signal.

I've also noticed(via ZapBarge) that before the T1 seizure that the call
launched will immediately go to an automated message claiming that not
enough digits have been dialed. The rest of the T1's become useless right
after it.

Once the T1's get into this state, even trying to launch a call directly
through the dialplan experiences the same behavior. Its like the T1 has
locked up.

The telco provider (quest) claims they aren't even seeing the digits placed
on the circuit. They say they see the channel being grabbed, but no digits
appearing.

Verbose and debug show nothing out of the ordinary.

Could this be an issue with the Digium card?  Both T1's experience the same
behavior at the same time. I've tried some different settings such as
callprogress=yes and busydetect=no but nothing has helped. Only restarting
asterisk seems to allow another 600 calls to be processed.

I'm using the latest asterisk release version 1.4.11 and zaptel 1.4.5.1

Regards,

Whit

Still having no luck with this scenario. Has anyone else experienced
problems with e&m wink lines?

I'm thinking that there could be problems with the timing settings in
zapata.conf, but documentation is pretty light.

How could the telco not be receiving enough digits when it works for 500
calls...?

Anyone have any similar experiences/ possible solutions?

Whit
