Partner Mail VS R1 won't hang-up after message left

[mcrgwb]

I have just installed a Partner Mail VS R1 system and
everything is working OK except when calls go to voice mail, once the caller leaves a message and hangs up, the line stays open until someone picks back up on the line and hangs up again. Any clues as to why and how to stop this would be much appreciated.

Hi mcrgwb,
I would try a reset first. If that doesn'r resolve the problem, then program the voicemail extensions on a phone to see if the R1's port is not hanging up. I had a similar fault with a PMVS R5. It turned out that we needed Bell to sent a positive disconnect from the CO side. That is a brief polarity reversal when the far end disconnects. If you get a tester on the line from the service provider, you can test the disconnect with him and prove your case. There may be a charge per line for this service. We whinned and got it free for the customer.
Also look at your disconnect timer. Here it is 800ms from the CO. You may have to shorten the timer on the Partner if the CO disconnect is too short.
Hope that helps,
-Chris

thanks itpphoneguy,

I tried the reset.... no luck.

Tried all kinds of seeting for disconnect timer with no change.

Programmed the VM extensions to a phone and it shows they are not hanging up.... so guess I'll be wrangling with verizon and hoping that I can get them to send the positive disconnect and that it does the trick.

thanks for your help!

You can check your disconnect supervision by doing very simple steps,call your self on the phone system using your cell or another line and when you pick up the call ,put it on hold ,you will see the line flashing green,then hang up the cell phone or the other line and watch the flashing green light it should disappear within seconds if you have disconnect supervision(CPC) if you still having flashing green light then you don't receive any disconnect supervision from your phone company and you should contact them,I hope that help..

Good Luck.

Hi mcrgwb,
Samh30 is right, and that is were you get a tester from the service provider on the phone. Have him enable positive disconnect from the CO and test again. It seems that the voicemail needs this in some locations. That's why I wanted you to monitor the vm ports. With positive disconnect enabled the call should drop in 1/2 s.
Let us know how you make out,

I've got a question here, is there no place to setup disconnect supervision on the Partner like there is on the Norstar? I'm a Norstar guy, but have been getting into the Partners lately and the more I do the more I'm liking them.

Hi Roldan,
There is no setting for disconnect supervision on a Partner vm. Let's just say, if the CO would sent a brief polarity reversal (positive disconnect as I understand it), all telco gear would drop the line. Just like magic. I don't know why some installations require this. I do know that sending the disconnect always seems to do the trick.

Is it really Verizon or a clec providing the dial tone?
Verizon provides "forward disconnect" on their lines,
also have seen customers use ISDN lines, you won't get a disconnect thru modem,same with SDSL modems, first thing is to verify who's supplying the DT.
