atcomsystems.ca/forum Forums TDM Business Telephone Systems Toshiba Telephones & Systems Lines autodialing other lines? Weird one...

Hi, I'm stumped on this one, I'm wondering if anyone's ever come across something similar. I have a customer that has lines 3 and 4 randomly calling line 1 (they said it happens with other lines somethimes, but usually it's these lines involved) where they see the line 4 button lit up, they see the caller ID saying line 4 is calling, they answer it and either get dead air or a busy signal. If they don't answer it, sometimes it'll go through the auto-att. and leave a message in the general mailbox with the busy tone.

Also, it's a CIX40 with GVPH VM, but there are no notifications set up that could be dialing out.

Could this be a carrier issue or does it sound like it's something in the system settings?

Also, the only thing atypical about their setup is they have a fax machine on an SLT port and their fax line is set up as line 5. However I double and triple checked everything there, I thought maybe the fax machine was calling them. But it's a different line and they assured me they're not getting fax tone.

Any ideas on this one? I'm stumped.

Sounds like you have the voice mail calling line 1 on someones mailbox notification. If they answer it have them press *.

If you aren't using VM notification out to cell phones or outside lines, remove the ability of the VM to use LCR. This will at least eliminate one possibility, as the previous poster noted.

It will also prevent hacking the VM to get free long distance calls.

They are not using any cell notifications, etc. That's the first thing I checked, so I can disable LCR as you said. Do you know which program number that is for disabling LCR on the VM?

Something else I'm going to try... since the users are all set with CO preference, instead of DN (hence they don't dial 9) I'm going to remove the (9)-LCR from the Flex Access Codes.

So that might help prevent the calls from completing, but it won't fix the root cause.

If you remove the (9)-LCR from the Flex Access Codes, that will prevent the vm ports from dialing '9'.

Before you do that, check the single line port that has the fax on it. Make sure that isn't using LCR to get out.

A couple ways to prevent an extension from dialing out (in this case the voicemail extensions)
- Changed the LCR to 2. If LCR 2 is not defined (default) then no calls are allowed.
- Enable DRL for all lines and create a destination restriction table 2(DR)as an allow table with no entries. Assign the extension to that DRL 2.
- Remove LCR feature from the COS.
- Remove 9 as LCR in flexible access code. This woukd effect the entire system.

It is not bad prectice to restrict the voicemail ports from being able to dial out. I have seen several systems hacked through the voiemail. If the customer addes notification, then you can allow local calling using DRL for the voicemail ports.
