AHHH! ok... yeah, you can do this but you will have to deal with the problem of
 the codecs that the telco's use for encoding the voice traffic over the
network... i don't know their names of numbers... that's all confusing for the
most part... i know that in some cases, it works and works well aside from the
network protocol paradigm that allows for packets to travel via different
paths... some have been successful with several of the available VoIP
products... others have not... some can only get 9600 while others may see
19200 or better... it really depends on the network, the codecs and QOS or
similar that may be in play...

i think that's a separate thing, altogether... other than maybe restricting
VoIP, it should not get in the way...
