We were just testing forwarding one of our numbers to a VoIP CLEC and ran into an issue that we've seen before but never figured out the cause of. It seems if you call us and immediately hang up - or if the call is forwarded by Verizon (which stills rings about ? of one time) the Zhone detects the ring and answers the call.. The Zhone however DOESN"T detect that it's no longer ringing nor that the user hung up. Instead it falls through to ring the operator eventually which can be frustrating. Does anyone know of a way to get around this? i.e. tell the zhone not to answer until ring #2 or something? I have a Wait,2 before Answer is my s,1, extensions but it appears the zhone answers immediately regardless.

Here Verizon takes 18 seconds before they reverse polarity. If you have a phone with lights in it, connect it directly to your line. Have someone call you and start timing when they hang up. You'll notice so many sec's later that it blinks. That's the hangup signal. -- Steve Szmidt ___________________________________________________________ HTML in e-mail is not safe.

I've noticed what you say but I don't think that's all of the problem, although it may well be related. If a caller calls in, stays on a while then hangs up Asterisk / Zhone / t1 card handles it fine. However if a caller hangs up immediately the system never recognizes it and we get a voice mail of "if you'd like to make a call please hang up and try again". When I say immediately I mean before Asterisk answers the actual call. Lets say I call our office, as the caller I get a ring. On the Asterisk side I get "Starting simple switch on 'Zap/2-1'". However it's roughly 5 seconds until Asterisk picks up the line. If the caller hangs up bteween this Starting simple switch and the Zhone actually answering the call then the hangup is never detected - instead if we transfer immediately to a phone we have an incoming call which is a dial tone, then goes to if you'd like to make a call please hang up and try again..
