Phantom call returns 1

Ok so here:

I had a thread about a phantom call. I reformatted the whole system, F989, and it helped a lot. However every Tuesday at 10:00am like clockwork it keeps calling us. Any other ideas. Maybe the phone company needs to take a look?

Thanks

Hook up a computer or serial printer to the smdr port and you might be able to see whats going on.

I had a look into your old thred and have a question when it rings, does it ring on the intercom button (lighting up green) or does it ring on an incoming line?
If it is the intercom then it could be that it is the Partner system trying to call the VM to update the time (for Messaging) but if you have another Voicemail then it would not recognized the inband DTMF and probably send it to the reception. If I am not mistaking then the inband signalling starts with 10### so if you can disable that in the voicemail to just be invalid then you could solve that.

It comes in on the incoming lines, not the INT. What is inband DTMF?

 

[Westi]

Inband DTMF is the information that the phone system sends to the voicemail so the voicemail knows where the call is coming from, it sends a series of DTMF signals as soon as the voicemail is picking up the call to the calling group 777. If you want to listen to it (nothing but a unch of tones) then assign your extension in #505 group 7 and call your extension, but don't forget to take it out again.

To your Problem, did you test the lines for AC voltage on it, that could cause the system to think that ther is actually a call coming in, and if it is every Tuesday at 10am then make sure you have the voltmeter on the line at that moment on the line that rings in.

Good luck

However every Tuesday at 10:00am like clockwork it keeps calling us.

On Tuesday, at 9:55am, take a single line phone, and a cord coupler to the control unit. Unplug the cord from the line port that the call comes in on, and couple it to the single line phone. If the single line phone rings at 10am, and the phone system does not, your problem is with the phone company, or anything like an alarm that may be connected ahead of the phone system.

TTT is right, that is the easier way to go.

 

[gromcal]

Thanks guys, I will try this and update you.

OK so i hooked the analog phone and the line did not do the phantom call. Anything else i can try to fix it?

Not that day, but it sometimes happens 10 times in a half hour, then nothing for 2 days.

Now manually set the clock to Tuesday at 9:55 am, and wait until it passes 10am. Do you still get the phantom ring?

If no, next Tuesday at 9:55am, set the date and time to something different, and see if you get the phantom ring.

You're trying to find out if it is something repeatable, that you can force to occur, or if it is something else outside of the phone system.

I would look at fire and burglar alarms, which wire up between the phone line and the phone system. I have also had some alarm installers find the voice pair of a Partner station, think it was a phone line (they got "dial tone" on their butt-set), and put the alarm's RJ-31X on that.

 

[Westi]

I am wondering if the calls always come in on the same line? if not then it might not be a device calling (like alarm system or any other device that tries to dial out) if it is always the same line, is it the main incoming line or another line in the hunt group? If it is not always the same line then is it because the first few lines are busy and it rolls over?
What type of voicemail is on the system?
Is it fully automated?
I still don't rule out that it is the partner system trying to upgrade the voicemail time and the voicemail is not an Avaya brand and doesn't know what to do with it.
If you tell me there is no voicemail at all then this theory is a goner.

There is voicemail, noone complains that it is not working however.

 

[Westi]

it owuld not affect the functionality of the voicemail, but the partner system calls periodically to the voicemail (embedded Partner Messaging and Partner Mail VS) to upgrade the time and that causes some voicemails to just transfer that call to the operator. This problem will not occur with Avaya voicemails like the Messaging or the Voice Messaging card it is only happening if there is a voicemail from a different vendor installed and they don't disable the dialstring from the System.
