We have a Partner ACS R7 phone system installed at a site. Occasionally when we are talking to a customer our employee will hear ringing in their ear and the customer will be dropped and another person is on the line. We have 6 POTS lines connected to the system. We have had the Telco (AT&T) our several times and they keep saying it is our equipment. So could it be the R7? How does a person not trying to call our Store get connected by seizing a line that has a call in progress in it.

Is the problem isolated to a particular telephone line? Can you duplicate the problem by plugging a single line telephone into the demarc and making a slew of test calls?

I have saw the same problem you are having and it was a bad channel bank.
But you will need to trouble shoot and have your facts together when you call the service provider.

Agreed. I don't see it as a problem with your system. This is something that you will have to fight with your service provider over and it would help if you can duplicate the problem with a buttset connected to the demarc. That way your equipment is out of the picture and they can't finger point.

Good luck!

You say You have 6 Lines,What is the Other card in the system ? If it is a 206 card, they can generate Ringing in your ear on an inbound call..The 206 power supply failed

I know what your talking about vance.
206's are bad for crosstalk.
But I have never had a 206 that would go from one conversation on a particular line to another line in mid conversation.

We have a 509ACS, 308EC, 400, SM VM (4box), & RAC Card.
These calls happen so randomly, once every couple weeks to a couple a day, that is it hard to capture or duplicate them since the people that barge into the call are not willing to tell us the information of who they were originially trying to call and give us the phone numbers.

We have talked to the Telco and they keep saying it is our equipment which we have replaced and rewired to the DMARC in the building. Thought thier might be a crossed pair somewhere.

It also does not happen to just one phone number at our site.

It really can't be your equip. causing this.

I would probably start by hooking a logger up to the SMDR port and have the customer log when it happens, what line, the number the inbound person was dialing ect. Then pool your facts together and have a vendor meet at the location in question.

How does a person not trying to call our Store get connected...

It's not your system, end of story. It has to be a problem with your service provider.
