Choosing an Integration Mode
Using the Hybrid Integration Mode
On the Octel system, you can designate which lines are used for handling
incoming and outgoing calls to Cisco CallManager and which are used for setting
MWIs. You must ensure that all MWI lines from the Octel system connect to the
DPA 7630/7610. The DPA 7630/7610 requires that you do not have any one line
designated for both incoming call processing and sending MWI commands. You
also cannot use the same lines for both incoming and outgoing call processing.
You can, however, use the same lines for handling MWI messages and outgoing
calls.
Once these 24 ports successfully connect to Cisco CallManager, they appear in
the database as Cisco IP Phones. If some ports are not used, they do not appear in
the Cisco CallManager database. For example, if you are only using 12 ports, only
12 IP phones appear in the Cisco CallManager database.
Additionally, a separate virtual IP phone (port 25) appears in Cisco CallManager.
This virtual IP phone is created automatically by the DPA 7630/7610, and it is
responsible for setting the MWIs on the Cisco IP Phones connected to
Cisco CallManager.
Using the Hybrid Integration Mode
If you want to connect Cisco CallManager to Octel voice mail and Definity or
Meridian 1 PBX systems, you must use the hybrid integration mode. In the hybrid
configuration, the DPA 7630/7610 handles processing and signaling among the
Octel, Cisco CallManager, and Definity or Meridian 1 systems (see
Figure
2-4).
