Configuring Restricted Access Domains

If you enter domains, the Cisco IP phones respond to SIP messages only from the
identified servers.
To configure restricted access domains, navigate to Admin Login > advanced >
Voice > System. Under System Configuration in the Restricted Access Domains
field. Enter fully-qualified domain names (FQDNs) for each SIP server you want the
phone to respond to. Separate FQDNs with semicolons. For example,
voiceip.com;voiceip1.com.
