<DIV><FONT face=Arial size=2>I believe there have been some advancements with
gateway and IOS features that allows you to run both voice and data over the
same PRI. Or at least I think I've read about.</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>The great thing about about running both voice and
data over the same PRI is that in the event of a WAN outage, you can use the
data section to connect to your HQ. If you have multiple PRIs for redundancy and
capacity, using one whole PRI for databackup will give you access to stuff like
voicemail, etc. ACLs and autodialiers should be able to get things working for
you.</FONT></DIV>

<DIV>someone can correct me if I'm wrong.... but my understanding is there are
two different types of PRIs: voice and Data.</DIV>
<DIV> </DIV>
<DIV>Voice PRI goes directly to the telco to go out on the PSTN. Data
can run to another location (ISDN) or to a telco. Since your wanting to
do Video you will then order a SPID (can't remember if that's the right name
or not) which is like a ISDN telephone number. (my memory is really bad
as this was in some CCNP classes I took about 6 years ago).</DIV>
<DIV> </DIV>
<DIV>Hope that helps.</DIV>
