Calling any Truecall experts.
I have a strange issue with a friend’s Truecall setup and am stumped as to what’s going on. Originally my friend had a DECT base station connected to the Truecall and that worked fine. However, they are now having problems with their eyesight and switched to corded big button phones. These are connected on standard extension cabling to the Truecall.
The problem is with one of the extensions only. When a call comes in, if it is "starred" ie the caller has previously been vetted and approved to be put straight through, all of the three phones ring. However, if it is an unknown caller and they have spoken their name, one phone on a particular extension does not ring when the Truecall rings to announce the caller, but the other two do. Calls can be made from this extension and it works normally when the Truecall is bypassed.
My first thought was it’s a problem with that particular extension, but why does it function normally under certain circumstances. I’ve also disconnected all of the other phones and swapped them round, but the issue stays with this extension. The phones are all Ren 1.
Can anyone thing of a reason for this behaviour. Thanks.
