Re: Compatible headset not working. - HP Support Community

Anonymous · ‎06-12-2015

I hope this is the right place to ask this question. I'm not very technical but I'll try to explain this the best I can. Yesterday my assistant and I got new IP phones from Comcast. They are both VVX400 but that's all I know about them. We both have headsets that are on the compatible list for those phones (they are Plantronics HW251Ns) but they aren't working. They both worked fine earlier in the day with our previous phones, so I'm sure the headsets aren't the issue. They connect fine and you can ever hear the callers on the earphone but they can't hear you speak into the microphone. The phone isn't on mute but the caller can't hear.

Comcast is supposed to be looking into it but since the issue appears to be the phone I was wondering, has anyone heard of this issue? Any thought on how to fix it?

Thanks.

Hello ntester,

welcome to the Polycom Community.

Our compatible list for headphones also lists the compatible cables. Most likely that is what is missing for you as depending on the prior phone you cannot simply used the same cables.

Please work with Comcast on this.

I'm having the same problem. I got the headset you say is compatible - Plantronics HW251N - and the cable 27190-01. I can hear, but the microphone doesn't work. Plantronics has replaced both pieces, so I'm pretty sure it's not the headset or the cable.

How did you resolve this issue? We have one phone with same issue. All other phones with same Jabra headsets are working fine. Headset works fine on other phones but one.

In the end, we had to replace the cable that ran from the headset to the phone. Even though it appeared to be compatable, it was not fully.
