Two-Stage Dialing

In two-stage dialing, the Linksys ATA device takes the FXO port off-hook but does not
automatically dial any digits after accepting the call. To invoke two-stage dialing, the VoIP caller
should INVITE the PSTN Line without the user-id in the Request-URI or with a user-id that
matches exactly the <User ID
treated as a request for one-stage dialing if one-stage dialing is enabled, or dropped by the
Linksys ATA device (as if no user-id is given) if one-stage dialing is disabled.
NOTE: If Authentication is disabled, a default dial plan is assigned to all VoIP callers.
HTTP Digest Authentication can be also used for two-stage dialing, as in one-stage dialing. If
using HTTP Digest Authentication or Authentication is disabled, the VoIP caller should hear the
PSTN dial tone right after the call is answered (by a SIP 200 response).
If PIN Authentication is enabled, the VoIP caller is prompted to enter a PIN number after the
Linksys ATA device answers the call. The PIN number must end with a # key. The inter-PIN-digit
timeout is 10 seconds (not configurable). Up to eight VoIP caller PIN numbers can be
configured on the Linksys ATA device. A dial plan can be selected for each PIN number. If the
caller enters a wrong PIN or the Linksys ATA device times out waiting for more PIN digits, the
Linksys ATA device tears down the call immediately with a BYE request.
NOTE: When the source address of the INVITE is 127.0.0.1, authentication is automatically
disabled because this is a call by the local user. This applies to both one-stage and two-stage
dialing.
The following table lists the parameters used in two-stage dialing.
