This may be way out in left field, but...
Is your modem doing compression or error correction? Seems I recall
that some algorithms work on blocks of data, which may cause delays.
You could try setting the modem to 14.4 KB (or 9600 if 14.4 isn't
supported). I suppose it could still try to error correct; maybe
the connect sequence would need to be changed somehow (more AT
commands).

Definitely not a modem expert,
