[cisco-voip] Need Help on CME Installation

Wed Jan 27 16:33:24 EST 2010

That's what I meant when I wasn't 100% fluent in telephony speak.  What
I was told is that the office used to just have a few POTS lines going
into the building in the earlier stages.  However, as the office grew,
they kept the lines, but kept adding new POTS lines to that office.
Eventually, they had to expand their phone system & created trunk groups
with the existing lines.  So when you ask "are these analog DID trunks",
I'm assuming yes.

As for the BRI, I will take your statement into consideration.

Something doesn't seem to add up on the current configuration.

You say they have "...13 POTS lines, 1 BRI, and 4 trunk groups.  There
are  15 DID numbers each trunk group for a total of 60 DID numbers."

DID doesn't work on POTS lines; 'trunk groups' in this case are logical
collections of some kind of trunks. Are these analog DID trunks or
something? And about the BRI: not sure what they were using it for, but
keep in mind they may have been doing something that will rely on having
out-of-band signaling, in other words the BRI used similarly to a PRI
for outbound per-station caller ID, etc.

Some of you may remember me.  My employer has put me in charge of
installing Cisco VoIP solutions for various offices around the state.
I've installed 4 of them so far, roughly with 40-50 users at each
office.  I've been getting real comfortable with installing them but all
those offices utilized a PRI.  So configuration of the system was fairly
simple and if all was set up correctly, you could just unplug the PRI
from the old phone system and plug it into the Cisco router and
everything works just fine.

For my next office, things are somewhat different and I'm not sure how
to approach it.  I was told that the next office does not have a PRI.
I'm not 100% fluent in telephony, but their current Nortel system
utilizes 13 POTS lines, 1 BRI, and 4 trunk groups.  There are  15 DID
numbers each trunk group for a total of 60 DID numbers.

For the new router, (which is a C2821), I went ahead and requested 4
VIC2-4FXO cards.  Are these the right cards to get?  I didn't get the
BRI card because I'm going to see if the phone company can convert the
BRI to POTS lines to save some money.  So that should give me a total of
15 POTS lines to plug into my router.  

The DID numbers span from 9421 through 9480.  However, on the
information sheet, there are other numbers as well (which I'm assuming
are the actual POTS lines' numbers).  These numbers are all over the
place, such as 1101, 1103, 1119, 2562, 4400, etc.  When I dial them,
they are picked up by the Nortel automated system as if I were dialing
the direct line specified in the DID number range.  So my question is,
when I program the CME/CUE, do I just configure ephone-dn according to
the DID numbers and leave out those other numbers?  I'm just wondering
if the Telco forwards all these "other numbers" to that DID's "direct
line".  I know for the Autoattendent, you just use 1 number.

Is this the right way I should be going about this?

Thanks for any help and sorry for the long e-mail.
