G.722 codec not working (at least with voip.ms)

Hi,

I've tried using the G.722 codec (enabled only that in the audio settings of Linphone), but when I try to connect to the echo test of voip.ms (4443), it fails with a "incompatible audio parameters" or similar message. I've sent a trace via Linphone (see: https://www.linphone.org:444//tmp/6363c451ee9ad_5769f23717e3eaf15e19.gz).

Linphone built on my GNU/Linux desktop works fine using G.722 with that same provided, so it seems to be a Linphone on Android specific issue. I'm using the latest linphone available from F-Droid (Linphone 4.6.14/SDK 5.1.62).

Thank you!

Maxim
