Remote Gateway 9150 Installation and Administration Guide 219
January 2005 Configuring the Remote Gateway 9150 unit
Scenario 4
All local inbound calls pass immediately to the host PBX and then are
“trombone” re-directed to the Remote Gateway 9150 units user’s primary PBX
DN key.
! Disable DN Discovery. This forces the Remote Gateway 9150 unit to use
local DNs (non-PBX DNs) and does not replace the local DN with the
primary PBX DN.
! Configure enough Bridge Ports to provide the desired level of call
blocking. For example, four inbound BRI calls forwarded to the host PBX
require four Bridge Ports.
ATTENTION!
This scenario creates tromboning on every call and uses
double DSP and bandwidth resources. Not only does this
trombone add additional delay but you MUST also ensure
that the DSP and bandwidth resources allow for this
situation. The duel encoding of voice calls causes further
degradation of voice quality, which can be unacceptable to
some users. Additionally, with DN Discovery disabled,
Local Switchover cannot be used. Therefore, all calls
within the Remote Gateway 9150 unit’s local office require
DSP and bandwidth resources.
