How PSTN-To-VoIP Calls Work
PSTN-To-VoIP calls can be made with two-stage dialing only. The only
authentication method available is the PIN method.
The ATA device takes the FXO port off hook after a configurable number of rings. If
PIN Authentication is enabled, it prompts the caller to enter the PIN number
followed by a # key. The Inter-PIN-digit timeout is set at 10 seconds. Up to eight
PSTN PIN numbers can be configured in the ATA device. If the given PIN does not
match any of the PSTN PIN values, the ATA device plays the reorder tone to the
FXO port for up to 10 seconds, and then takes the FXO port on-hook. If the given
PIN matches one of PSTN PIN values, the ATA device plays dial tone to the FXO
port and is ready to accept digits for the target VoIP number from the PSTN caller.
The collected digits are processed by the dial plan associated with the PIN
number.
NOTE If Authentication is disabled, a default dial plan is used for all PSTN callers.
