6400 speakerphones

[tricie10]

Does anyone know if the built-in speaker phone on the 6400 digital series telephones is full or half duplex?

6402's are listen only, the rest are all half duplex as far as I know. We use 6408's and 6416's

It depends on how you program the station as well.

Type=6408D+ you get Speakerphone: 2-way

However if

Type = 6408 you get Speakerphone: 1-way

Hope that helps.

We have some 6408 & 24's but they don't seem to be that good at 2 way. The speaker and mic cuts out. It is possible though!

I don't believe there is a speakerphone made that is full duplex! Otherwise you would get feedback.

It is Half duplex. I use Polycom 550d in conference rooms they are setup as 6408d+ phones.
