Multiplexing Configuration
This method enables you to share a single voice mail system with multiple
Cisco CallManager systems or another PBX system. Using the multiplexing
configuration, you can integrate SMDI with multiple PBX systems, including:
• Multiple Cisco CallManager clusters (see Figure 5-3)
• Legacy PBX system and Cisco CallManager (see Figure 5-4)
Configuration Tips
When integrating SMDI links from more than one PBX system, refer to these tips.
Note, however, that this is not a complete list of the items you must configure;
these are tips specific to the multiplexing configuration. Refer to the “Configuring
SMDI Settings on the VG248” section on page 5-19 for a description of all SMDI
configuration tasks.
