Headsets & Snom 300

#1
We got our Snom 300 phones today and have just managed to get them configured properly, we had to enable the proxy setting in order to be able to receive calls and setting up each phone as an extension wasn't exactly obvious. Then again, maybe I was doing something wrong.

Anyway, my main question is this - Are our old BT headsets unsuited to the Snom phones? They plug in ok and they work but we have background static/buzzing with all of them. Any suggestions for a fix, or are we going to have to buy new headsets?

#2
Can you tell me the make and model of your headsets pse?

If you order the extensions before you buy the phones, the phones arrive fully configured........too late for you I realise :-(

Extensions were already in place before we ordered the phones. I think I have them set up correctly, although it was trial and error.


I think the headsets are BT Converse 1 models, they are 7-8 years old.

I've since tried two different headsets on each phone and have the same problem each time. Maybe the specification of the old BT headsets doesn't meet the requirements for the Snom phones?

Ive also noticed that if I check the phone's options, under Headset Device it says "None", although I have set this to RJ Conn and pressed the tick.

I tried a plantronics generic headset with a snon 320 and had similar problems with noise. I couldn't get it to work well even after trying all it's various settings.

The snom headset works very well, though, I think you really have to use a snom device with these phones.

It may be mains hum.

It can be cured by using an earthed power supply (the standard snom PSUs are not earthed) or connecting an earth wire from the ethernet port to a earth point - such as a radiator or water pipe.

You could try earthing one to see if that solves your problem. We can supply earthed PSUs for £15.

Otherwise your answer is to buy snom headsets.

It is most definitely mains hum. Thanks for pointing this out.

I have made a cable up to earth the handset, and will be making up a more professional solution in the next few days.

The earth wire has solved the background static/hum. By attaching an earthing wire to the right hand (viewed from the rear of the unit) Ethernet port and fixing the other end to a screw on the back of the PC case, the static is eliminated completely.
