Hi,
I’m having problems getting my comfort II alarm and pabx to work together. Comfort is connected to the telephone provider at the Tel In and the Tel Out goes to my paxb, which sees the line as a normal external analogue line.
My problem is with the polarity of the Tel Out. Set one way the local ringer and access from the local phones into comfort using the * key works, but the PABX gets upset picks up the external call on the first ring and proceeds to drop the call. (no good at all as I can't get any calls!) Set the other way the PABX is happy and external calls work fine but, the comfort ringer (doorbell) does not work and the local access does not work either. I’ve tried swapping the polarity of the Tel In to no avail. I recall on my old comfort pro you had a tuning parameter to set the line polarity – does UltraII have this?
Thanks in advance for your help
Mark

The pabx looks like it is responding to the * key as a special programming key, and cuts off the outside line when it hears this tone. Can you see if the programming can be disabled on the PABX?
Comfort I and II has a setting to set the delay from lighting the handset to detection of the * key for local access, this is in Telephone > Answering, but changing this value may not help you
Have you tried changing the polarity of TEL IN to see if it has any effect?
Anothr alternative you can consider is to connect Comfort to an analog extension of the PABX, ie after the PABX. This allows you to call the Comfort extension to access it. For doorstation, yu need to have another phone connected to Comfort TEL OUT. However do this at your own risk as Comfort my not be able to seize the telephone line to dial out if all outside lines are busy.

When an incoming call comes in the PABX rings once, then goes “mad†and effectively picks up the call (the PABX does not have an answering machine or anything).The caller assumes the line has rung once and then gone dead. When I use 9 to get the external line and use the * command’s I hear a voice from comfort. The doorstation ringer works in this configuration. Outgoing external calls work fine.
Connected the other way round incoming and outgoing calls work fine. When I press 9 for an outside line (connected to comfort) and use the * commands comfort does not answer and I get a voice from the telephone line provider along the lines of unrecognised feature command. The doorstation ringer does not work, and I can't access comfort locally over the phone.
It seems I can have either the PABX working or Comfort Local phone access and the problem appears to be they both expect different line polarity from the TEL OUT.

Rather strange behaviour!
have you tried if a normal telephone connected to Comfort works for both polarities?

With just a local phone, not connected to the PABX, the polarity only works one way around.

It appears like one of the redundant optocouplers is damaged, thus only one polarity works. Comfort will still work this way, however your problem with the PABX remains, in that if the telephone wires are connected the "right" way, your PABX does not like the * key

It is covered, depending on when you bought it. Just return it to the distributor (?) whom you bought from
However you would still have problems with the PABX, and you would not see any diference in operation with the correct polarity connected
