A straight T1 clear channel line can get expensive depending on the
distance, plus that makes it an OPX (off premise exteansion) line. You
should use EM for the tie line between two routers, then some sort of WAN
circuit to bring the two together. You can do anything such as FXS to FXO,
etc,. but the proper voice way to do it is EM. You could do PRI (voice
pri, not ISDN) to carry the digits to the other PBX, clear channel, VoIP,
VoFR (then you bring in a router of some sort to CODEC and encap the voice).
Basically you need a pyhsical pipe to carry the voice between two
I work for a voice company right now, so I am getting all the info right
from the voice guys. (Also, I can't seem to escape these Cisco Press
authors. One of my instructors at my QoS class at Cisco is Wendel Odom.)

The CID test doesn't have any voice questions!?!
I think there's a new version of the class that has some voice stuff in
it,
but I don't think the test does yet? Anyone know for sure?
If the CID test does have voice questions, then I suspect that it's
written
from the point of view that you have already taken some basic voice
classes. For example, you should probably take the CVOICE class (or get
the
CVOICE book).
So, I'm looking over my CVOICE material right now to try to answer your
question. I think that any T1 line can act as a tie line. A T1 can handle
24 voice calls and the necessary voice signalling. It was designed to be a
voice circuit. I'm sure someone will correct me if I'm wrong. ;-)

Hello,
What voice port is needed to connect a PBX in New York to another PBX in

Thanks
