CO Disconnect Problems 1

[phonesaz]

I am working with a Legend R7 w/ DuVoice voice mail on an 012 board w/ ring gen. When a call transfers to the voice mail, the voice mail will not disconnect the line after the caller hangs up. If I unplug the line from the system it immediately releases the port and activates the message light. If I dial 9 after the call, which tells the voice mail to hang up, it disconnects immediately. If I make an incoming call and don't go to voice mail it hangs up immediately. So it would appear that the problem is the system recognizing disconnect from calls in the voice mail system that don't have the disconnect signal physically input. The lines are set to loop and yes for tt disc. Any suggestions? This is my own system so its making me look bad. The only other unusual setup item is that my dial tone is delivered via my cable company, not a standard LEC or CLEC. This exact same system/voice mail has been used (by me) with both a T1 from a CLEC and dial tone from the LEC so I am beginning to wonder if the cable co is the problem. I know on the Partner we used to occasionally have issues with some CLECS and we corrected it by making some type of millisecond timing adjustment on the Partner system. Sorry to ramble but wanted to let you know what I have tried/thought about.

You could contact the cable company and see if there is any adjustment they can make on the voltage drop to signal a disconnect.

I remember reading something about differences between 8 OPX cards and 012 cards; do you think the 008 card would have any different results? Don't want to do a board renumber if I don't have to. Cable company can't respond for 2 days - I already had a call in to them.

You need the line signal boosted BEFORE the PBX- the 008OPT boosts it AFTER the PBX to a remote single-line phone - so it will not have an effect.

Who is the cable company. If it is COX i have had the same issues with them and the POTS lines they ptovide.

Your tests prove that the PROVIDER is NOT PROVIDING a "FORWARD DISCONNECT" signal.

That is usually a MOMENTARY Drop in VOLTAGE or LOOP CURRENT of 50 to 200 MILLISECONDS.

Of course, ever since the break up of the BELL SYSTEM, all of the STANDARDS went out the window.

The vendor needs to provide that DISCONNECT SIGNAL, PERIOD.

As far as the OPT and the 012, the OPT should NEVER be used for voice mail, as per BELL LABS way back when.

You can play with SHORT or LONG hold disconnect, but I am more than certain that this is an issue for the service provider.

As I said, your tests prove this.

Thanks - as you know, the programming options on the Legend are somewhat limited (I already tried the short/long hold disconnect route.) Are there any Magix releases that offer more options? Also - kwing - is is Cox I am working with - may end up switching to the LEC as my only fix.

 

[tdaugirdas]

There are no other Magix internal programming options. I have heard that Viking makes several products that could help. One is a CPC Disconnect box that provides a reliable disconnect when you do not get one from your service provider. The model is CPC-1. You would need one per line.

I had COX come out and prove that the lines were within spec and they found they were not up to snuff and got them fixed and the problems went away.

I have a repair call in to them - we will see. Thanks.
