Wierd Hangup Detection Problem

From: Pete McBraida

Hi All,

I am using a D\4 PCI card with TAPI to produce a simple IVR app under windows 2000.

I am having a problem detecting hangup through TAPI, at the moment it is configured to detect hangup through a loop current drop. It works fine on one of my pc's but when I put the card in on another pc it doesn't detect the disconnect even though the I am testing it with the same phone line. I am wondering if this is some kind of configuration problem, but I can't see any difference.

I am wondering if the installation on the other pc is not quite right, as there are a few other symptoms with the other pc,

1. It occasionally fails to detect a DTMF digit
2. Occasionally the DCM gives me an error when starting or stopping the cards

Has anyone come across this problem before or have any suggestions? It is beginning to drive me nuts!
