Meeteasy Mid2-EX-B Conference Phone with 2 Expandable Microphones

This phone is a great idea with bluetooth/landline/USB options for audio, but it doesn't bridge them if you are using USB. It does however bridge the calls from PSTN and skype IF you use the 3.5mm cables instead.The audio quality is pretty good, especially if you use the extended microphones. We had an echo issue with connecting it through a Nortel PBX system and analog converter, but once we bypassed those this worked much better. The seller worked hard to help fix the issues. It didn't get 5 stars because it doesn't do the call bridging on USB and so we had to return it as the room was already wired extensively and that was the configuration we planned for.
