Bluetooth Wireless Speakerphone

Your can use your iPhone for conference calls when there are a few people around the table, and a one or two people are at a remote location by using the iPhone conference call feature to connect to the people at the remote location. You could use the inbuilt speakerphone function of the iPhone, but in that situation it is limited in volume.

This Uniden wireless speakerphone connect via Bluetooth to your iPhone and can be heard quite well, so is a very workable solution. The picture of the one below is a Uniden that I picked up this morning at the bargain price of $30, but even if you don't have access to that sort of deal, these Bluetooth Speakerphones are available from Wow and similar electronics stores or online and work very well. The Model number is Uniden BTSC1300. They have a standby time of several hundred hours and a talk time of up to 20 hours between recharges.
