Polycom SoundStation2 Expandable Conference Phone – Product Review

The Polycom SoundStation2 Expandable Conference phone is an excellent choice for holding an audio conference between two locations using just a normal analog (PSTN) phone line/analog port of a PBX. It is very much like a normal analog phone, but it doesn’t have a headset. It is made for audio conference and that is pretty much what it does.

There are so many situations when small teams from either side may want to discuss with each other. This product can be used in small to medium sized conference/discussion rooms and it has a microphone pick-up sensitivity of 10 feet. So, even if one speaks normally from a distance of 10 feet, the other side should be able to easily listen to what they are saying. In case of bigger conference rooms, one can connect the optional Polycom SoundStation2 extension microphone kit (2 additional microphones) to increase the area of coverage.

This product, like all other SoundStation models, comes with three Cardiod microphones that gives it a 360 degree coverage. The phone can automatically activate the mic that is closest to the speaker. Polycom’s acoustic clarity technology claims to eliminate noise, ear strain & repetition and it does a decent job at that. Besides, the voice conversation is quite natural as the phone supports full duplex technology.

The Polycom SoundStation2 Expandable Conference phone has everything that a normal phone needs to have. It has a 12-key telephone keypad with normal phone functions like mute, volume up/down, redial, hold and even three context sensitive soft keys. It is very similar to a speaker phone, but is made for enterprise grade audio conferencing. One can even connect a cell phone (2.5mm RCA jack included, but for other interfaces on the cell phone a converter/adapter might be required) and use the SoundStation2 as a hands-free conference attachment to the cell phone.

  • Some users may find that the price is slightly higher (especially when compared to speaker phones), but considering the quality and microphone pick-up range it is a good choice for audio conferencing for small teams
  • Not all locations have analog PSTN telephone lines and this phone doesn’t have a direct IP connectivity (RJ-45 interface)
  • 25 entries in the phone-book is insufficient in most cases
