When you use the DPA 7630/7610, it emulates a PBX for the Octel voice mail
system and emulates up to 24 Cisco IP Phones in Cisco CallManager. In this
setup, when a call goes to voice mail, Cisco CallManager rings one of the
emulated Cisco IP Phones (which is also a port on the DPA 7630/7610). The
DPA 7630/7610 translates this ringing to a corresponding Octel voice mail port.
Other aspects of the phone behavior that the DPA 7630/7610 translates include
the formatting of the information on the display, line light behavior, call
transferring, and setting MWIs. For example, to activate a Definity MWI, the
Octel system goes off-hook on one of its ports and dials a feature access code
(typically *4) followed by the extension number. The DPA 7630 must recognize
this and translate the sequence to the appropriate set of messages for
Cisco CallManager.
The DPA 7630/7610 connects to the IP network and accesses a
Cisco CallManager TFTP server to get its port configuration and
Cisco CallManager list. After the configuration information has been transmitted
using TFTP, the DPA 7630/7610 tries to register its virtual port (port 25) to the
first Cisco CallManager from the Cisco CallManager list using Skinny Client
Control Protocol (SCCP).
This virtual port handles all the MWI commands sent from the Octel to
Cisco CallManager. As Octel voice and MWI ports are connected to the
DPA 7630/7610, each connected port on the DPA 7630/7610 then registers as a
30VIP IP phone with the Cisco CallManager.
To implement the simple integration mode, you must connect the DPA 7630/7610
to the Octel and Cisco CallManager systems using these guidelines.
Because of the wiring differences on the DPA 7630 and the DPA 7610, you
connect them slightly differently.
