• Use the proxy server. If a SIP server is present, use the SIP proxy server for SIP message interaction.
• Use the domain name as the destination address. Without the need of obtaining the IP address of
the destination, the client only needs to know the unique domain name of the destination on the
network, and communicates with the destination through DNS.
• Use the E.164 Number to URI Mapping (ENUM). ENUM translates telephone numbers into Internet
addresses.
Configuration prerequisites
If a SIP server is used to forward calls, complete the configurations on the SIP server.

Configuration procedure (3: destination domain)
If the destination address is a domain name, the device performs DNS lookup by using either of the
following modes:
• Type-A—If you use the dns-type command to set the DNS lookup mode as a-record, or both the
domain name and destination port number are configured, the device uses the Type-A mode to
perform DNS lookup.
• SRV—If the domain name is configured but the destination port number is not, use the dns-type
command to set the DNS lookup mode to SRV.
