Without Authentication
This scenario can also be implemented without authentication, using one-stage or
two-stage dialing, as in the HTTP Authentication case. The default VoIP caller dial
plan is used in this scenario. Authentication is performed when the method is none
or when the source IP address of the inbound INVITE matches one of the
VoIP
Access List
patterns.
The following table lists the parameters used in VoIP to PSTN Call With and
Without Authentication.
