12.6 DNS
You can use the device's embedded domain name server (DNS) or an external, third-party
DNS to translate domain names into IP addresses. This is useful if domain names are used
as the destination in call routing. The device supports the configuration of the following
DNS types:

Internal DNS table - see 'Configuring the Internal DNS Table' on page 142

Internal SRV table - see 'Configuring the Internal SRV Table' on page 143
12.6.1 Configuring the Internal DNS Table
The Internal DNS Table page, similar to a DNS resolution, translates up to 20 host
(domain) names into IP addresses. This functionality can be used when a domain name
(FQDN) is configured as an IP destination for Tel-to-IP routing in the Tel to IP Routing. Up
to four different IP addresses can be assigned to the same host name. This is typically
needed for alternative Tel-to-IP call routing.
Notes:
•
The device initially attempts to resolve a domain name using the Internal DNS
table. If the domain name isn't listed in the table, the device performs a DNS
resolution using an external DNS server for the related IP network interface,
configured in the Multiple Interface table (see 'Configuring IP Network Interfaces'
on page
124 ).
•
You can also configure the DNS table using the table ini file parameter, DNS2IP
(see 'DNS Parameters' on page
482 ).

To configure the internal DNS table:
1. Open the Internal DNS Table page ( Configuration tab > VoIP menu > Network
submenu > DNS submenu > Internal DNS Table ).
2. Click Add ; the following dialog box appears:
