Outgoing call process
To place outgoing calls, users can either pick up the handset on the telephone or
press a line appearance key. There are two types of line appearance keys:
!
host call appearance key
Use this key to place a call through the host PBX.
!
local call appearance keys
Use these keys to place calls to other stations in your office, or to place and
receive calls through the local PSTN. You can define up to two local call
appearance keys on each digital telephone.
For a detailed description of the outgoing call process, refer to the sample
illustrations beginning on page 20.
Incoming call process
When a user places a call through the host PBX to a user at the Remote Gateway
9150 site, a connection is made from the RLC to the Remote Gateway 9150 unit
and the host PBX completes the call. If a connection cannot be established, then
the call rings until it is forwarded to voice mail by the host PBX. Refer to
Chapter 6, “Using Remote Gateway 9150 stations,” for a more detailed
description of the incoming call process.
When someone places a call through the PSTN to a user at the Remote Gateway
9150 site, a connection is made from the central office to the Remote Gateway
9150 unit. The number that outside callers dial is the number assigned by the
ISDN service provider to the ISDN BRI B-channel carrying the incoming call.
You can configure an unanswered incoming local call to Call Forward to a DN
on the host PBX. The Bridge Port connects the call to the host PBX and it can
then transfer to voicemail.
