Amplified speaker for 712 phone

12_phone speakerI have a customer with an Netvanta 7100 and a 712 phone that they use as a

conference type phone.  I am trying to find out if there is some way I can

connect an external speaker (amplified) to produce a louder conference.  The mic

is fine but many around the table cannot hear the incoming callers over the

speaker on the 712. Any ideas or suggestions is greatly appreciated.

Re: Amplified speaker for 712 phone

While it is certainly possible to open the phone and solder wires from the speaker to an external amplifier I would recommend against it. 

High-quality speakerphones are a combination of electronic, acoustic, and mechanical engineering working together.  One of the key features of good performance is the reduction of coupling from the far-end caller back into the microphone(s).  An external amplifier and speaker will drastically alter the phase, direction, and level of the far-end caller as received by the microphone of the speakerphone, resulting in echo, feedback, and generally bad performance.

Spend the bucks for a well-designed conference room phone such as the Polycom Soundstation 5000 or similar.
