Task 2: Setting up a Dial Rule (optional)
If you have configured a prefix directly on the SIP Peer in Task 1, this task is not required. For
redundant integrations, this step will be required. As a best practice, the dial rule configured for
VCS should be last in your logical list of dial rules.
See the “Dial Rules” section of the of the “Call Server Configuration” chapter in the DMA System
Operations Guide for detailed information about using dial rules.
To set up a dial rule for VCS calls:
1 Select Admin > Call Server > Dial Rules.
2 Click Add.
3 In the Add Dial Rule dialog box, enter a description for your dial rule.
4 In the Action drop-down menu, select Resolve to external SIP peer.
