Source Address Settings

The Source Address Settings defines which DID number(s) may be used as a sender ID for the outbound SMS trunk. These DID numbers appear as the CLI to the recipient of the SMS. The “allowed” sender IDs may be selected from the available DID numbers acquired from DIDWW. A filter is provided to enable users to list specific DIDs. By default, all DID numbers with SMS OUT capability in the customer’s account may be used as the sender ID on outbound trunks (Fig. 3).
