The kind of information you need to get
You need to know what kind of trunks these
are (central office (CO), foreign exchange
(FX), etc.) and whether they use any special
services (such as T1 digital service). You
also need to know what kind of signaling the
group uses. For example, you might have a
CO trunk group with ground-start signaling
running on a robbed-bit T1 service.
For incoming or two-way trunk groups:
What number or numbers do outside
●
callers use to call into your server
over this group?
What is the destination extension to
●
which this trunk group delivers calls?
Does it terminate at an attendant or a
voice-mail system?
For outgoing trunk groups:
What extensions can call out over this
●
trunk group?
Direct Inward Dial and Direct Inward/
Outward Dial trunks send digits to Avaya
Communication Manager. Tie trunks can
send digits, depending on how they're
administered. You need to know:
How many digits is your service
●
provider sending?
Are you inserting any digits? What are
●
they?
Are you absorbing any digits? How
●
many?
What range of numbers has your
●
service provider assigned you?
