Choosing an Integration Mode
Using the Multiple Integration
Only the lines connected to the Octel system (maximum of 16) appear as
Cisco IP Phones in Cisco CallManager. Additionally, another 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 MWI
messages on the IP phones connected to Cisco CallManager.
Using the Multiple Integration
You might use multiple DPA 7630/7610 systems if your network needs match any
of the following scenarios:
•
Connecting Additional Ports to the PBX System, page 2-13
•
Connecting More Ports to the Octel System, page 2-14
•
Using Multiple DPA 7630/7610 Systems for Redundancy, page 2-15
•
Using the DPA 7630/7610 with Cisco CallManager Clusters, page 2-19
Connecting Additional Ports to the PBX System
If you need more MWI ports to the Definity or Meridian 1 system, add an
additional DPA 7630/7610 in hybrid mode (see
Figure 2-7
). However, you cannot
use all 24 ports for Definity or Meridian 1 MWIs. You must configure the
DPA 7630/7610 following the guidelines for the hybrid integration (see
“Implementing the Hybrid Integration” section on page 2-9
for details). Each
DPA 7630/7610 translates the call processing information and MWI commands
from the Octel to Cisco CallManager. In summary:
•
On each DPA 7630/7610, use ports 1-8 and some of ports 9-16 (those not
used as MWI lines) for call processing.
•
Set some or all ports 9-16 from each DPA 7630/7610 as MWI lines.
•
Each DPA 7630/7610 translates the call processing information and MWI
commands from the Octel system into calls and MWI commands on the IP
telephony network.
•
On each DPA 7630/7610, connect ports 17-24 that correspond to an MWI
line on ports 9-16 to the PBX for PBX MWI commands.
