We have two of the Polycom Soundstation IP7000 conference phones at our company. As of late we have been having issues with one of them in particular.
When making a call between the station and another phone, the call goes through fine and the audio is working. We then call another phone to do a conference call. The call goes through and the phone will answer without issue and audio goes both ways. The moment we press the button to make it a conference call, the audio dies completely.

It is always useful to include the currently used SIP or UC 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.
