ENUM Dialing for Outgoing Calls

Configuring DNS Servers

To configure the DNS servers to be used by the VCS when querying DNS:

•System Configuration > DNS.

You will be taken to the DNS page.

•xConfiguration IP DNS Server

Address 1 to Address 5

Enter the IP address(es) of up to 5 DNS servers that the VCS will query when attempting to locate a domain.

In order for endpoints registered to the VCS to make outgoing calls using ENUM dialing, you must configure at least one

DNS server for the VCS to query. For resilience, you can specify up to five DNS servers.
