Check SMPP ESME trunk connection status

Check whether your application is bound to the DIDWW SMSC with an SMPP ESME trunk. The status shows the bind that your application establishes. Checking it does not connect or bind your application.

Before you begin

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

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

• Your application must be configured to bind with the trunk’s credentials. See Bind an SMPP ESME trunk.

Step 1: Open the status window

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

2. Locate the SMPP ESME trunk and click the Actions button next to it.

3. Select Check Status.
