I wouldn't expect any cellular connection to pass VoIP reliably.  Think
about it.  The phone call is on the same airwaves but is prioritized.  The
data gets the lowest priority.  Again, all my testing has left me using
only g.729 when I really need to do VoIP over cellular, but it's never been
perfect.
