Bridge Port
A Bridge Port is a proxy port that represents a local or inbound PSTN call to the
host PBX. When a local incoming call on a Remote Gateway 9150 unit needs
PBX services, the Bridge Port obtains a PBX presence on behalf of the local
call.
Bridge Ports can represent the following types of local calls:
!
Call Forward: A Local and Remote call made to another Local and Remote
telephone uses Call Forward to connect to a third telephone on the PBX.
!
Call Transfer: A Local call to a Local and Remote telephone uses Call
Transfer to connect to a local trunk or a host-based set.
!
Conference: A Remote call to a host telephone can connect to trunk call(s),
or if you are on a call to a local trunk, you can connect to host telephone(s)
to create three-or-more-party telephone calls.
To configure Remote Gateway 9150 Bridge Ports refer to page 250.
Host controlled call mode
When a user places a call to someone at the host site, or when someone from the
host site calls the Remote Gateway 9150 site, the call is in host-controlled call
mode. Calls in host-controlled mode are routed through the host PBX. Refer to
the sample illustrations on pages 20 and 22.
Locally controlled call mode
When a user places a call from a local call appearance key, or the call is to
another telephone at the Remote Gateway 9150 site, the call is in locally
controlled mode. Calls that are initiated from the local call appearance key are
routed through the local PSTN. Calls to other extensions in the Remote Gateway
9150 site are routed only through the Remote Gateway 9150 unit.
The host PBX is not involved in locally controlled mode calls. Refer to the
sample illustration on page 24.
