Null or
one of: "source",
"digest" or
"both"/"all"
Default Interpretation
Null Alert-Info fields from INVITE requests will be
compared against as many of these
parameters as are specified (x=1, 2, ..., N)
and if a match is found, the behavior
described in the corresponding ring class
(refer to Ring type <rt/> on page
be applied.
Null
Default Interpretation
Null Sets the name of the method for which
validation will be applied.
WARNING: Intensive request validation
may have a negative performance impact
due to the additional signaling required in
some cases, therefore, use it wisely.
Null If Null, no validation is done. Otherwise this
sets the type of validation performed for the
request:
source: ensure request is received from an
IP address of a server belonging to the set
of target registration servers;
digest: challenge requests with digest
authentication using the local credentials
for the associated registration (line);
both or all: apply both of the above methods
