One detail I could not find information about: does G726 use the same
10ms frames as G711?

I've noticed the diference in sound fidelity, already, after switching
from G711u to G726-32, but the sound continuity is fautless, and
fidelity is very much acceptable!

I understand not all Voip providers are equal when it comes to call
sound quality, and I notice that particularly when calling mobiles
"abroad", and even landlines in "far" destinations like Japan, sound
continuity, in particular, is very easily discernable in such cases,
between my 2 Voip providers: VoipCheap and VoipFone ;-P

I'm in Portugal, I could go into detail, but summing up, I've given up
calling mobiles in the UK using VoipCheap ;-)

I'm willing to lose fidelity, for the sake of continuity and
synchronism, although other than Voip calls to landlines in Japan
through Voipcheap, I only have complaints about some calls to mobiles
- but there, the mobile network probably plays probably the most
important role :-S
