6900 speakerphone support

[Rafael Jimenez]

What means "full duplex speaker" in the 6921 datasheet?. What is the difference between 6921 and 7911 in this matter.

Thanks.

Full-duplex means two-ways hands-free speakerphone with active echo cancellation.

The 7911 doesn't have microphone at all so no speakerphone.

Hi Rafael,

As Paolo stated, on a 7911G IP Phone you can just listen over the available Half-Duplex speaker. In order to speak you still need to use the handset.
