Phone not ringing - goes to Voicemail with SmartHubPlus

straightwave — Fri, 14 Feb 2025 09:06:15 GMT

Hi All.

I have a new FTTH installation based on SmartHub Plus, using its DV phone connection to our original POTS Panasonic DECT base . Because of physical siting issues in the house , I connected the SHPlus phone socket to the original house phone wiring (many metres) and the DECT base connected into a remote socket. Pls see the diagram .

The set up worked for a few days but ystrday the phone stopped ringing for incoming calls and went directly to VM. I reconnected the phone at the SHPlus and at the remote location and it all works as expected again - phone rings on incoming.

What would cause the DV / SHPlus to inhibit ringing > VM?

I wonder if the SHPLus has an issue with driving the line length (capacitance / leakage) when I connect to its phone socket.? Does any one have any experience of SHPlus PSTN phone socket driving long wires?

Dare I ask what the drive capability / output impedance is at the phone socket?

Thanx for reading..

If it worked for a few days and then worked again on reseating the connections it suggests a duff connection somewhere.

SmartHubPlus drops the phone connection spuriously. Reports "not registered"

A second occurrence of our Panasonic Dect phone becoming disconnected by the SmartHubPlus.

By a software resetting of the Smarthub Plus (using the home network/ IPaddress) , the phone becomes registered again and functions.

It does not appear to be a hardware connection problem, therefore.

The phone is a Panasonic DECT station plugged into the "PSTN" socket on the SMartHub Plus.

Any constructive ideas, please.

Because mobile coverage is poor in our location we critically depend on the "landline" for contact, medical appointments, etc.

Thanks!

when you connected the hub phone socket to existing openreach socket did you also disconnect the old incoming openreach line from master socket?

Hello IMJolly.

Thanks for your rapid reply..

Ok this is a good point. Your suspicion is that the old connection pair and Smarthub signalling would be in conflict ? Which sounds plausible.

Wires from the overhead pair from the most recent master jack (Ca2020) were disconnected at their IDC terminations - at least that was the intention- the old wiring bundles were a bit hard to separate and trace.

I have now accessed the old copper pair at the point of entry at the very original master jack (ca 2000s) and isolated them, and reset the Smart hub.

The dial tone is now discontinuous however - the usual pitch but ~50/50 on off with a 1 second repeat. I cant recall now - shouldn't it be continuous?

Regards..

@straightwave

That alternating tone suggests that you might have a voicemail message.

Thanks, you are right. That was it.

I didn't know that and no instructions with the new FTTH install.

Recovered the voicemail by dialling 1571.

Cheers!
