I'm looking for a solution for a portable conference phone. Currently I'm using a Polycom Soundstation that works with an analog line. The quality of sounds is obviously is not great so I was wondering if there is a more modern solution that could help with our needs. It would be for a room with about 20 people around a long table so I need to make sure there is decent range for them to be heard over the phone. I was looking into something like a Jabra Speak 710 UC Wireless Bluetooth Speaker device that would work with a cell phone but I'm worried about quality of sound over a cell phone connection pushed to a BT device.
Any help would be appreciated.
