Enter the IP address(es) of up to 5 DNS servers
that the VCS will query when attempting to
locate a domain.
These fields must use an IP address, not a
FQDN.

In order for endpoints registered to the
local VCS to make outgoing calls using
URI dialing to endpoints that are not

registered to the local VCS or one of its
neighbors, you must configure at least one
DNS server for the VCS to query. For resilience,
you can specify up to five DNS servers.
Without DNS, calls made using URI dialing will
still be placed if the destination endpoint is
locally registered or registered to a neighbor
system as locating these URIs does not require
the use of DNS.

URI 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 Serve

•

The DNS server(s) configured here are
used as part of both the ENUM dialing
and URI dialing processes.
