Use the following procedure to configure DNS SRV record pre-caching.
CONFIGURING DNS SRV RECORD PRE-CACHING
1. Using a text-based editing application, open the startup.cfg file.

Enter a value for the DNS SRV service URI. For example:
sip dns srv1 name: _sip._udp.example.com

Enter a value for the DNS server weight. Valid values are 0 to 65535. Default is 0. For

in a future release.
5. Enter the parameter, "sip dnx srvX port, where "X" is a value from 1 to 4.
Enter a value for the port number on the target host. Valid values are 0 to 65535. Default
