Feedback on Wireless VOIP Phones

[MToby]

We are having an issue with wireless phones 7921 and 7925 causing feedback when we perform paging. I am assuming that the cause of the feedback is because the mouthpiece on the wireless phones is too sensitive and is hearing the output over the paging speakers, thus causing a feedback loop.

My question is, do you know of any settings either on the phone or on the network equipment that would address this issue? Maybe something that causes the mouthpiece to be less sensitive?

Thanks,

Mark

There is no setting on the 792x phones and the FXS/FXO port you have is already doing the maximum 128ms of echo coverage that it can. You'll need to use a non-live recording mechanism. If you have a paging server from Syn-Apps or SingleWire they can support this natively. If not, you can try this Bogen module:
