Trusted Servers
The Trusted Servers setting provides a means of blocking unauthorised SIP traffic. When
enabled, each account's Registration server, SIP server, Outbound Proxy server and
Backup Outbound Proxy server will be used as sources for trusted SIP traffic. All unsolicited
SIP traffic (for example, INVITE, NOTIFY, unsolicited MWI, OPTIONS) will be blocked
unless it is from one of the trusted servers with the enabled accounts.
If additional trusted sources are required beyond what has been specified with the enabled
accounts (for example, if IP dialling or other types of server traffic need to be secured), use
the Trusted IP settings on the Security page.
