[cisco-voip] Types of PRIs: "Voice", "Voice, Video and Data", "Unrestricted Digital"

[Scott Voll]

someone can correct me if I'm wrong.... but my understanding is there are
two different types of PRIs: voice and Data.

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).

Hope that helps.
