6408D+ Speakerphone issue
- Thread starter coop292
- Start date
There may not be a problem. If there is, changing the phone is generally the only option.
The speakerphones on 6408D+ sets are one-way only speakers. That is, they will take the sound that's the loudest, (either in the room, or coming in from the distant end) and make that the thing they will use.
Consequently, the phone is in either transmit mode or receive mode, but not both at the same time.
They require a bit of discipline to use in a conference call. If both parties begin speaking at the same time, only one will be heard. (Usually the loudest person.)
Background noises can also affect them. Locally, nearby computer cooling fans, overhead ventilation, and other noise sources can cause the speakerphone to switch to transmit when the user want's to hear what's being said by the distant user.

Correct. I know the phone isn't a true duplex phone, but on more recent versions, especially the "serialized" model, this problem is much more noticable. I wonder if there's perhaps something in the circuit making the phone go to "transmit" mode more easily. The older Lucent models don't seem to be as touchy.
The best thing to do is reset the phone in the location it will be used as a speaker.
Moving it from where it was last reset can affect the profile of the ambient noises and echos it uses to determine when to switch from transmit to receive.
If that doesn't fix the problem, consider getting a more high end speakerphone. (Like a Polycom.)

Generally, you will unplug and plug in the phone while it sits in the location (and pointing in the direction) it will be used as a speakerphone.
If you have an office where you have a small conference table, and you use the speakerphone there, you would place the phone in approximately the same spot, and unplug the phone. When you plug it back it, it will build a profile of the ambient noise, and the echos from nearby objects. (Walls and such.)
The profile is lost when the phone is unplugged, and rebuilt when it's reset. (Plugged in.) When you plug the phone back in, you should try to be as quiet as possible for the profile to be built properly.

Just a thought, I have problems with the 6408 series also. My most notorious problem came from a user trying to use the speaker phone with an air vent directly above her. Needless to say to correct the problem we moved the phone to the other side of her desk.
