Manage SMPP SMSC trunks

Manage existing SMPP SMSC trunks from the SMS Trunks page. View the credentials that DIDWW uses to bind to your SMSC, edit a trunk’s settings, move it to another Server location, or delete trunks that are no longer required.

Before you begin

• An active DIDWW account is required. Sign in to DIDWW.

• An existing SMPP SMSC trunk is required. If you do not have one, see Create an SMPP SMSC trunk.

View SMPP SMSC trunk credentials

1. In the DIDWW User Panel, go to SMS > SMS Trunks.

2. Locate the SMPP SMSC trunk and click the key icon in the Credentials column.

The credentials window shows the values that DIDWW uses to bind to your SMSC. To show the password, click the eye icon next to it.

Field	Description
System ID	The System ID that DIDWW sends in the bind request.
Password	The password that DIDWW sends in the bind request. Hidden by default.
System Type	The System type that DIDWW sends in the bind request, if the trunk has one.
SMSC Server Host	The hostname or IP address of your SMSC that DIDWW connects to.
Allowed Source Addresses	The DID numbers that can be used as the sender ID. Any if all DIDs with outbound P2P SMS enabled are allowed.

To change these values, edit the trunk.

Move a trunk to another Server location

To change which DIDWW SMPP server connects and binds to your SMSC, change the trunk’s Server location. Your SMSC connection details stay the same.

Important

Before you save a new Server location, make sure your firewall accepts connections from the IP address of the new location. See Server locations and IP addresses.

1. In the DIDWW User Panel, go to SMS > SMS Trunks.

2. Locate the trunk, click the Actions button next to it, and select Edit.

3. Select a different Server location.

4. Click Submit.

DIDWW then binds to your SMSC from the new location. To confirm the bind, see Check SMPP SMSC trunk connection status.
