"digital sets do not produce DTMF on icm calls"

That's what I was sort of wondering myself but on a 7208 phone there isn't a soft touch "open" button so technically you are pushing the 6 and sending a tone.

Plus, Dave has told us that he can hear a tone coming from the door phone speaker as long as he holds the button down on his buttset.

I asked a Nortel guru here in my area about it and he thinks it has something to do with offsite restrictions. He says an ATA, even though connected to a station port, acts like a trunk call. It's the same as calling in from offsite and accessing the door. That's why I suggested the cell phone transfer and it should work even without line appearances providing at least one intercom is assigned to the door phone.

On the topic of HG or ringing multiple DN's, I normally use a third party solution as well but that's the advantage to using a Nortel unit. The Nortel unit can page a "chime" sound to multiple phones.

Can hear the tones, not only from my buttset, but also any analogue set connected to the ATA again for as long as I hold the 6 button.

rustynails....have you got a link to Viking for me. I have to find a solution.

A third party solution will connect to a trunk port so you must have another line-in available on the phone system.

I have used the Viking which makes different grades of door speakers (vandal resistance). I have also used the Viscount and the TeleDoorBell . The Viscount and TeleDoorBell are cheaper, but not as vandal proof.

Using a 3x8 system & only 1 line so trunks are no problem. Thanks Twisted Pair for the info, I'll check them out.

Now that this scenario has moved to using an available trunk--I have several customer sites that use a trunk port for connection to a doorbox. This link will take you to the Viking doorbox page--https://www.vikingelectronics.com/products/search_alpha.php?mykeyword=doorbox
Simply program the phones-including the cordless-to 'appear & ring' or 'ring only' for that line port that the unit connects to. No more complaints from the nice lady. :rolleyes:

What about from a digital set to the door phone. That was my point; if the digital set can acitvate the switch by pressing 6, then it must be something other than DTMF that is making it work.

DAve I'd like you to try something.

From C/L call the door phone DN, then try to release the door latch.

Another solution I've used is the external page relay instead of the controller.

Bobcomm....Thanks for the link. I'll take that route if I can't get Nortel to do it to it...

Rustynails....Yes been there, tried that and digital set work fine. Therefore I'm coming to the same conclusion.

Marv....I can't honestly say whether or not I tried calling the DN from the C/L. I'll try that tomorrow if time permits, if not, it won't be until Friday as I might go to the telephone fair in Mtl on Thursday. Need to see one of my suppliers anyway to shove a few "DOR" sets down his throat (Dead On Receipt).

I like your idea of using the paging port. Can't see why that wouldn't work. Would I be able to bypass the DOC completely (& eventually remove it) or would you suggest running this in parallel with the DOC?

By any chance have you tried setting the doc to some other digit such as 0 or * or #? Its a far off idea but it could be that something weird would work on the s/l tones.

Have you tried setting the called phone to a real extension, not a non-existent one, and see if that made any difference?

A Viking doorbox (W-1000, W-2000, W-3000) and a Viking RC2A on a CO port would work just fine. As stated above, you would program it to ring or appear and ring on what phones you want and the RC2A gives you a contact closure for the door strike.

The cost new is similar or less to the Norstar doorbox and DOC. The one advantage to the Norstar is a programmable doorbox tone that is not like a line ring.

If you use just the Viking doorbox you can use the paging port for a contact closure but you have to hang up and hit a paging button. I would caution you not to use the full door opening power through the paging contact, it is not meant for that.

When I did this in the past, I would put the door opening current through the arms of a Radio Shack 12 Volt DC relay and then send one leg of the 12 volts through the paging contacts to pull the relay down.

I can email you a diagram if needed, just PM me.

I just put in two new door boxes and two DOCs last night. One DOC worked perfectly and blinked and the other one hooked to the same power supply just came on as a dim red, no blinking, no operating. I hate bad out of the box. And, hitting the reset button did nothing to make it work, nor did taking the power off multiple times.

For this much money, you would think they would test them and they were made in Canada, not asia.

Dave if you look in the doorphone manual, the proceedure to use the page relay is in there. NO DOC is required, but you also can't be using external paging on the system.
