obi100 won't ring phone on incoming calls
Geoffster:
Hello all,
I've just bought an OBi100 here in the UK. I manually configured the device to work with Sipgate. I only changed the settings necessary for it to work with Sipgate.
Outgoing calls no problem. Incoming calls don't seem to ring standard UK phones. I've tried two now with an appropriate adapter "BT socket to OBi100". If I pick up the incoming call it is actually there but the phone doesn't ring so there's no way of knowing.
Anyone got any ideas how I might troubleshoot this one?
Cheers
Geoff

Hello Geoff - welcome to the forum.
In most of the world the telephone is a two-wire device. However, here in the UK we like to be different ;)
A lot of UK phones are three-wire devices. You need an adapter with a capacitor to direct the ringing to the third wire in the phone. Like this:

Look carefully at the "BT" style plug on the end of the phone lead. Does it have three pins? If so, then the solution above should work.
There are many other settings to get the ringing exactly right to suit UK phones, but none of them should stop the phone ringing.

Thanks a lot for that. I'll order the Maplin adapter right now and see if it works. Top man, definitely worth a try.
The two phones I have both have 4 metal contacts on the plugs. At least one of them worked and rang well with a Cisco voip box I have....?

Four pins is normal for a traditional UK corded phone. Two pins will be the line (-ve & +ve, sometimes called A leg and B leg), one pin will be the ringing wire and the fourth pin is for an earth supply to the phone (needed in some old PBX systems for recall).
I can't explain the Cisco voip box, unless it was designed for the UK market. Just now there is a mix of devices around. My dect phone base (branded British Telecom) is two-wire and works fine. Most modern devices will be two wire and are designed to work on UK systems.

Ianobi,
Great. That information is really helpful. Thanks for taking the time to reply to me. I've ordered 2 Maplin adapters.
I did try the Obi100 with our Dect phone and it did ring it. I've just checked the BT plug on the DECT base station....just 2 metal contacts. Exactly as you suggest.
So if I can find some ordinary cabled phones with 2 wires perhaps I won't need the Maplin adapters?
Cheers
Geoff
