Using the Hybrid Integration Mode
If you want to connect Cisco CallManager to Octel voice mail and Lucent PBX
systems, you must use the hybrid integration mode. In the hybrid configuration,
the DPA 7630 handles processing and signaling among the Octel, Lucent, and
Cisco CallManager systems (see Figure 10-11).
