Digital voice - HD Call Quality

[earthmover45]

Following a recent migration from fttc to fttp the landline was required to go digital. After some teething troubles with caller display & incoming calls with the essential digital home phones where is an outstanding warning for the HD Call Quality.

Does anyone know what the Digital Home Phone service activation graphic shown in the migration order with a warning against the HD Call Quality means and how this is fixed please?

Good morning @earthmover45, thanks for stopping by!

What kind of phone have you connected to your hub?

Also if you connect to your Hub Manager via http://192.168.1.254/, then select your landline number, does this confirm that the service is up and running with your handset registered?

Hi @Peter_W thanks for your follow-up.

I have checked the SH2 Manager page and and can confirm that Handset 1 is registered and is a Home Phone Adapter with BT everyday handsets. Handsets 2 & 3 are BT Essential Digital Home Phones type 090709 both registered and working. The Full Fibre 900 Broadband service is connected and reporting WAN link speed just under 1000Mbps 

The Phone service is running however I am unsure if I am getting HD Call Quality as previous posting. How does the BT network know that I have HD Call Quality issues, is it detected error rates or types of codec used?

See the service activation to Digital Home Phone in the migration order with the link to the graphic showing the warning for HD Call Quality as previously posted.

Not entirely sure why you are so bothered about HD call  quality. Unless both parties in the call have it there is no benefit (which is slight in any case).

HD quality is only possible if the other end is using the BT Digital Phones. 

Normal PSTN calls only have a single 64Kbs slot, and I suspect other VOIP services may use even less.

Just putting it out there, but though I’m using a normal DECT cordless phone plugged into the hub,  I have noticed that the voice quality has improved (clearer?) moving to DV. Didn’t expect it to have done. Perhaps the analogue voice  was somehow being degraded over the last mile what with all the broadband signals being carried too. Appreciate they were  completely out of band compared with voice. But anyway. A surprising improvement.

The  issue appears to be resolved and is displayed below. @pddco is right about the clearer, fully quiet voice quality with Digital Voice and the BT Essential Digital Home Phones. The home phone adaptor with the BT Everyday dect handsets do have a low level background hiss which might be a unfiltered data.

 I believe my original question is now resolved and am happy to close this thread as Resolved. Thanks to everyone who contributed.
