My office is with 2talk via their cloud pbx.  We have 6 handsets (all Yealink T28P) which have their Line 1 registered to each persons own local number DDI.  Line 2 is registered to our main office number using the 2talk 'one number' functionality so they all ring at the same time and anyone can answer the call.  This has been working well for a year or so.
An odd thing has occurred with one of the handsets - incoming callers (regardless of whether it is via line 1 or 2) hear an annoying hum.  The hum can't be heard on the receiving handset.
We've tried these things to try and isolate the problem:

- plugged handset into a different Ethernet port in a different part of the building.
- grabbed a spare handset and configured it with the same lines.

It appears to be an issue at 2talks end I think?  I've raised a support ticket but they've been less than useful.

Any solutions from this forum would be much appreciated.

Cheers

Hi

We use heaps of Yealink in $dayJob and I've seen this plenty of times before.

My money is on it being a hardware fault with the microphone part of the handset piece that you hold in your hand.

Try swapping just the handset (but not the cable) with another phone, and see if the problem moves with the handset.

Hope it's that easy for you :)

Ps, you can get replacement handsets on their own too.

Pps, I've just re-read your post. By 'handset' I mean the piece you hold, not the phone part itself with the keypad on it (which I think you meant when you said handset?).

So you are saying that it doesn't matter what device you provision that line on, the hum follows it? i.e. it's not a device fault but something on that line?

Are you using the Yealink auto-provisioning provided by 2talk?




Opinions are my own and not the views of my employer.

just to be clear you only have the hum with the one phone? or any phone that is configured with the pitcular extention, imho i highly doubt the later.

Are you using a power pack or a POE switch?

If you are using a power pack, try swapping it out, the filter cap may be failing.

If using a POE switch, try another port on the switch.

Thanks for all of your advice.  Sorry for the delay in replying - phones are powered by their own power pack; the hum was happening also on another phone that was configured to the same extension; swapped hardware but still had the issue.
Update - this morning the problem seems to have disappeared!??!!??  2talk had not yet closed the ticket so I'm thinking that they've been tinkering with something at their end?  It's got me baffled.
