SoundStation IP 7000 Bad Call Quality with External Microphone

We are experiencing the following issue with our SoundStation IP 7000:


Whether an external microphone is connected or not, the sound quality when connecting to a conference bridge or an individual number is extermely bad.  We can hear the other line very well but the receiver perceives the call as if we are in a wind tunnel or very muffled.


The way, we have the IP 7000 setup is as follows:


  • Approx.  15 x 15 ft. Room (Floor to Ceiling Windows)
  • 1x Polycom SoundStation iP 7000 is sitting on a coffee table in the center of the room surrounded by sofas
  • 1x Polycom Extension Microphone is connected to the IP 7000 and sits on the executives desk approx. 6 ft. away

We have exchanged and tested the external mics but the sound quality remains being bad.


Thanks for any help in advance.

Re: SoundStation IP 7000 Bad Call Quality with External Microphone

Hello david.tran,

welcome to the Polycom Community.

It is always useful to include the currently used software version as issues experienced may already be addressed in a newer release.

This also allows yourself and others to check against current software release notes.

The above is also stated in the "Read First: Welcome to the Polycom VoIP Forum"

Therefore the Polycom VoIP FAQ contains this post here:

Question: How can I find out my SIP UC Software Version or the BootROM Version of my Phone?
Resolution: Please check here

In addition could you kindly provide some feedback if this is a new unit or a used unit?


Have you tried this in another room yet as flat surfaces all way around are the worst environment for a conference phone.

Please ensure to provide some feedback if this reply has helped you so other users can profit from your experience.

Best Regards

Steffen Baier
