asterisk users - Sep 2003 - Cisco ATA 186 / FXO card problem

Hello,

I've got a Cisco ATA 186 from Vonage plugged into my Asterisk box with a
X100P card.   This works great for the most part, but I'm having a
disconnect supervision problem.   

I suspect the Cisco device doesn't provide any sort of analog disconnect
supervision when it gets a SIP BYE message indicating the far-end has hung
up.   This causes Asterisk to leave the channel up indefinitely sometimes,
if the call was in an app that doesn't time out eventually.

Does anybody know of a trick to make either Asterisk deal with the Cisco's
lack of disconnect supervision, or a way to make the Cisco ATA-186 provide
this signaling?

Thanks,


Mark

We had calls dropping every few mins but after we have upgraded ATA's
firmware to 2.16
the problem was solved.
