Setting up MCDN over VoIP with fallback
To set up this system:
1 Make sure the M1 ITG meets the following requirements:
• ITG Kit [NTZC44BA] Delta 24.24
• Rls25.30
• S/W Packages 57, 58, 59, 145, 147, 148, 160
2 Ensure that the M1 ESN programming (CDP/UDP) is compatible. For information on this,
refer to your M1 documentation.
3 On the Business Communications Manager 2.5 Unified Manager:
• Set up outgoing call configuration for the VoIP gateway.
• Set up a remote gateway for the Meridian 1.
• Ensure the dialing rules (CDP or UDP) are compatible with the M1. For information on
CDP and UDP, see the Business Communications Manager 2.5 Programming Operations
Guide.
• Configure the PSTN fallback, and enable QoS on both systems.
• If target lines have not already been set up, configure the telephones to receive incoming
calls through target lines.
MCDN functionality on fallback PRI lines
To be able to use MCDN functionality over PRI fallback lines, set up:
• Check MCDN PRI settings on the M1. For information on this, refer to the M1 documentation.
• Ensure SL-1 (MCDN) keycodes are entered on the Business Communications Manager 2.5
and the PRI line is set up for SL-1 protocol.
For a detailed description of setting up fallback, refer to Chapter 5, “Configuring VoIP trunks,” on
page 59.
