PSTN Trunk
PSTN trunks allow you to forward incoming calls through Direct Inward Dialing (DID) to the Public Switched Telephone Network (PSTN).
Note
Incoming calls forwarded to a PSTN trunk are charged per minute. The rate and availability depend on the destination PSTN phone number.
Create PSTN Trunk
To create a PSTN trunk, go to the Trunks section, select Voice IN, and click Create New, then select PSTN Trunk.
The Create PSTN Trunk page will open. Enter the following details:
Friendly Name: A name to identify the trunk.
PSTN Phone Number: The destination number to which calls will be forwarded.
(Optional) The Assign Trunk to All DIDs option allows you to automatically assign this PSTN trunk to all your DIDs.
Warning
Enabling Assign trunk to all DIDs will assign the trunk to all of your DID numbers, overwriting any existing trunk configurations.
To create the PSTN trunk, click Check Rate & Availability to view the per-minute PSTN rate. Next, click Submit to finalize the trunk creation.
Note
The per-minute rate depends on the destination number. For detailed pricing information, contact customer.care@didww.com.
