<DIV><FONT face=Arial size=2> From what I've read, ISDN is
*not* a very good platform for VoIP because it introduces a great deal of
latency and jitter. Latency will cause communication to be
difficult. Jitter will cause the calls to be choppy sounding.

<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2> Are you able to connect another
* box directly the one of the * boxes you have in place and try to place a call
over a local network? If this works ok, then you know its your
trunk.</FONT></DIV>
