G722 on Mitel 5320

[is99]

I'm trying to use G722 on Mitel 5320 in SIP mode
Mitel tech info about this phone say it supports G722
When I go to the Web GUI of the phone I see in the list of codecs G722.1

The problem is that when I select it the web page just reloads and then the codec get switched to G711

Any idea what could be the problem ? Anyone was able to use G722 in SIP mode on these phones ?

Thanks a lot

I know the data sheet (http://www.mitel.com/sites/default/files/Mitel-MiVoice-5320-IP-Phone-Datasheet_EN.pdf) says it supports it, but I have never seen it in SIP mode, it doesn't even list it in the User Agent Capabilities during negotiation, but it works fine in MiNET mode.

also, as far as I know, it only supports G.722.1... Not quite the same as G.722.
