It's G711. The kbit/s rate isn't really that important when you're
talking about these things, more the sample rate (8k for G711).

It's okay quality, but not when you compare it to G722 and the other
wideband codecs, or CD quality etc.

It possibly to get the same sound quality but that doesn't mean it
always happens, protocol implementations, processing and of course
acoustics all play a part.

Perhaps this would be better discussed on something such as the NZVoIP
group, it's really not at all on topic here.
