One-stage dialing is possible if <One Stage Dialing> is “yes”, <VoIP Authentication Method> is “none”
or “HTTP Digest” or if the source IP of the inbound INVITE matches one of the patterns specified in
<VoIP Access List>. To perform one-stage dialing,
the Request-URI of the INVITE to the PSTN Line
should have the form
dialed-number@SPA-Address
, where
dialed-number
is the target PSTN
number as “dialed” by the VoIP caller, and
SPA-Address
is a valid address of the SPA, such as
10.0.0.100:5061.
If the PSTN line is currently not available, the SPA replies to the INVITE with a 503 response.
Otherwise, it compares the
dialed-number
with the <User ID> configured for the PSTN Line. If the
