IDNet Help / Re: Phone doesn't ring on VoIP

Last post by nowster - Oct 17, 2025, 11:12:52

My suggestion: they're not expensive. Just try it!

Increasing the ringer voltage won't help if that voltage isn't appearing on the connector pin that the phone's expecting. The capacitor does that.

UK phone wiring has the bell wire separate to reduce tinkling in older phones which had mechanical bells, when there were multiple extensions on the same line. If the bell was connected directly to the line sometimes it would very lightly ring (tinkle) in sympathy with the sound on the line.

Having it on a separate wire, connected via a capacitor in the master socket, meant that any extension in use could short out the bell wire when its handset was off the hook. This prevented the tinkling.

Wiring diagram

Older GPO wiring, before the now familiar BT 431A plugs, was even more complex. For example, here's the wiring diagram for a simple house extension system with three phones: http://www.samhallas.co.uk/repository/n_diagrams/4000/N4502.pdf In addition, pre-BT phones had their bells wired in series, with low impedance ringing coils; BT plug phones have their bells wired in parallel, with high impedance ringers, hence the tinkling problem and the separate bell wire.

Thank you for that tip and sorry it has taken me so long to respond. I would like to believe it would do the trick. Since writing that post my router failed so now I have a Tp-Link router with its own ATA. Do you think your suggestion would still work? If it is the solution to my problem, how come iDNET support has never mentioned it? I must have spoken to every one of their advisors on this topic. Others on the internet suggest the answer is to increase the ringer voltage. I would really like to understand this problem.

I raised this problem with IDNet Support and following a fix Caller ID works as expected for me. Excellent service!

Thanks for that information John7. However, When I first started using UBOS callerID worked. Recently, it has stopped working and display simply says "Incoming Call". Without callerID there is no caller log information so pretty useless. Something seems to have changed in the system.

UBoss only does +44 which doesn't trigger the caller information on domestic phones. Its purely a a service to firms who use phone systems that can covert +44 into actual caller information as mobile phones do where every call is preceded with the international code but they have the coding to use it with your contact list which is why calls diverted to a mobile phone displays the right information. Its probably a very good system in the right use but no for domestic phone use.
