Connecting to PSTN to VoIP Services Configuration
Max Rings All Callers are accepted for service but it will rings until it
reaches to Maximum Rings set by the Admin. Then it will
prompt for Secret PIN to connect to VoIP Gateway.
Authenticate Caller ID Here it will authenticate the Caller ID in the Added list to
prompt for Secret PIN to connect to VoIP Gateway.
Secret PIN Caller is prompted to enter a PIN right after the call is
answered.
How PSTN-To-VoIP Calls Work
1. Authenticated user:
In this case, Caller ID will authenticate to access the FXS port to make VoIP call. First,
set the Max Rings on Bridge Settings > PSTN to IP. This will allow number of rings to
be dialed on FXS phone port before authenticating the Caller ID. Secondly, we need to
add PSTN phone number in the format of “Country Code+Area Code+Phone number”.
(E.g.: For India 91+80+41515998) in VoIP Config -> Bridge Settings -> PSTN
to IP ->Authenticate Caller ID list to connect VoIP gateway.
Once it is authenticated, ATA device plays dial tone of the FXS port to make VoIP call.
2. Un-authenticated user:
This will apply only if the Caller ID does not match with the values, which is listed in the
VoIP Config -> Bridge Settings -> PSTN to IP - > Authenticate Caller ID.
In this case also ATA will prompt for Secret PIN to connect to VoIP
Gateway and it rings on the FXS Phone Port until it reaches to Maximum Rings set by
the Admin i.e. Phone 1 Max Rings. By default Maximum Ring set to 12 Rings. If the
given PIN does not match with any of the PIN values, the ATA device will re-plays IVR
up to two times to prompt for Secret PIN, and then ATA will disconnect the FXO line. If
the given PIN matches one of PIN values, then ATA device plays dial tone of the FXS
port to make VoIP call.
