I have a related symptom to the post below, but probably a different cause, so I have posted separately.
I have a set up with Panasonic DECT phones (single connection) and Comfort. All was working fine, door bell ringing phones via the ringer unit.
However, a further analogue phone has recently been connected to the system, an old-fashioned rotary dial phone, bakelite with a proper bell as a 'feature' in the living room. It has been reconditioned to work on a 'modern' phone system. For incoming phone calls, it all works fine, DECT phones and this traditional bell phone all ringing normally.
However, the Comfort door bell no longer rings the phones at all when this old-fashioned phone is connected. Disconnect it and it works fine. Presumably, adding this phone has increased the total REN on the system, or has affected the ability of the RGR05 to generate a ring. The relay clicks inside Comfort as normal - but no ring. Disconnect the offending phone and it works.
Is there a way of tuning the parameters so that RGR05 delivers the same ring power / profile as the phone line pass through (which works)? Or at least still drive the Panasonic DECT phones? (I have read through the tuning guide but couldn't work out which parameter adjusts the ring - most seem to be related to the intercom itself)
The old phone loads the RGR05 so that it cannot ring the phones at all. It is not possible to just ring specific phones connected to the TEL OUT, so I am afraid there is no solution except to disconnect it
Surely if it has increased the total REN above the max allowed then you can prove that by temporary disconnecting some of the other phones to see if it then works as expected. Would tell you for sure if it's's REN related. Been a long time since I've thought about thinking about this but isn't the limit REN 2 across all phones?
Thanks for the responses.
As I said in the original post, there are two phones (New Panasonic DECT + Old Phone) connected plus Comfort. There is no problem with incoming phone calls, all phones ring normally. REN is perhaps therefore the wrong culprit. The phone line, as I understand it, is 'passed through' Comfort and incoming calls ring normally.
The issue is with Comfort dialling the same phones when the doorbell is pressed. There is no ring on the doorbell from any phone when the Old Phone is connected. So Comfort and the BT telephone exchange are ringing the phones with a different ring profile / power and I was asking if I could change that to see if I can find something that works. But apparently, as Ident says, this is not possible.
The Old Phone will have to remain an ornament. Shame. It works well!
