Dial Plan (required) 

---

What is required for a dial plan

A dial plan must be administered for message VDNs on the DEFINITY ECS.

Although ASAI message calls do not use any port resources, you need a dial plan on your DEFINITY ECS large enough to support the number of messages you want to queue simultaneously.

In addition, the CentreVu Computer-Telephony Server security database must be set up with a list of numbers for the valid VDN extensions. Please refer to the administration guides for each system for further details.
