Creating SMS HTTP OUT Trunk

Outbound SMS traffic is delivered via DIDWW’s high-capacity, global platform, directly peered with a range of selected incumbent local exchange carriers. Configuration, management and monitoring of outbound SMS trunks is available through the DIDWW User Panel. Under the “Trunks” section, select the “SMS” tab, navigate to “Create New”, and click on “HTTP IN” (Fig. 1).

Fig. 1. Accessing Outbound SMS Trunk information

To create a new outbound trunk, select “Create New” and a window with the required Outbound Trunk SMS settings will be opened (Fig. 2).

Configuration options are:

Friendly name - The friendly name of the trunk. Callback URL - The server’s address for posting SMS delivery notifications. Allowed IP addresses - IP addresses from which access to the API is allowed in the format (IPv4|IPv6)[/mask].

Note

After you allow an IP address(es), you can only access the API, if you are connecting from the allowed IP address. Any access attempts from other IPs will be blocked. This is a security tool that you can use to help prevent malicious activity on your account.

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).
