Handset speaker telephones are fine for listening to voicemail or conducting short conversations, but they usually don’t offer the technology that makes natural two-way conversations possible. For business-critical clarity in small rooms and offices, and having the functionality of being Bluetooth enabled, the affordable Polycom VoiceStation 500 is the clear choice. You may also want to check out the ClearOne Conference phones as an alternative solution if you are on a tight budget.
