Does CP7941 support the G.722 codec ?

Hi Guys,

I viewed he data sheet of CP7941 IP phone but find no G.722 codec supported on it.

But when I called with 2 CP7941 in LAN, the codec showed on the both phones is G.722.

I believe the codec should negociate between the end points, but why it was G.722 even the endpoints does not support the codec?

Dont it cause by the phone firmware ? The firmware we use is SCCP41.9-2-3S for SCCP phones.

Yes, it support G.722

You will also need a wideband handset or headset for the feature to fully work.
