Absolutely a T1 is a high speed Internet link. If you cannot handle 
about 20 simultaneous VOIP calls on a T1 then you are using the wrong 
software.

One single dedicated voice channel is 64 Kbps. A T1 is 1.5 Mbps and 
could handle 23 lines when connected to a PBX in the olden days.

If you cannot do the same while using a packetized protocol that doesn't 
even have to transmit much of the time, then something is very wrong, as 
I said.

Or I suppose you could be trying to do CD quality voice. That's a waste 
of time.
