I am using comfort with a PABX(NEC XN120) If i use the PABX to access comfort it doesn\'t detect the * and i get a message from BT saying number not recognised.
The line wiring is BB Filter>Line In then Line Out>PABX.
If I use a normal phone connected to line out it I can sign in and if I phone in I hear the Answer message and can sign in. There is nothing in the phones manual about the * having a function once you have an outside line.
I don\'t really want to connect comfort as an extension.
Board is comfort Ultra II FW 5.121.
Has anyone used comfort with a XN120 or have any suggestions?

First change the polarity of the telephone wires into Comfort TEL IN - you can just plug in the terminal block in reverse. Sometimes the polarity revseral can have an effect of sensitivity
if that does not help, try changing the Tuning Parameter 83 (AFE Line IN Gain Local Phone) in Configuration. The range is from 0 to 20 with larger numbers giving higher gain- default is 4. Change the value lower or higher one or step at a time in either direction and selectively download - mo reset required. The PABX may be attenuating or amplifying the the * DTMF tone

I have changed the polarity on the line in. the * now works but it will not accept the code (1234) all i get is wrong code no matter which user i try. it works on the test phone.
Tweaked 83 down to 5 from 6(not 4??) and it works.
I would be lost with out this forum!!

Same system similar problem. The local phones aren\'t ringing when The doorbell is pressed. the rely in comfort is clicking. could it be the Phone system not detecting the ring signal from COmfort?
Thnks

Can you check if you connect a normal phone to Comfort if it rings? If it does not it may be a problem with the RGR04 or the connections

It definetly works with a local phone connected.
- slychiu - 08-01-2008
That shows the RGR04 is working
Check the jumper settings on the Ringer module shown in the RGR04 Manual at https://www.cytech.biz/Downloads/Files/200/rgr04man.pdf
Try the larger ring amplitude and different frequency.
Otherwise check that the ringing signal (about 50V RMS) is getting through to the PABX line

Thanks Chui, not on site for a while so will file the problem for now. we did blindly play around with the jumpers to no avail but will try again next time.

I have finally had a chance to look at this issue again.
I have tried all the different combinations of the jumpers. I have tried reversing the polarity of the Line in/Out and there is 50v RMS at the PABX when i press the doorbell.
Still no go.
Any other ideas? Has any body else used a NEC PABX with comfort?

Found a setting in the program for the PABX (page 14-02) that sets the incoming trunk to immediately ring. This has got it working! Yipee
