Integrating Asterisk with SMSLocal for Bulk SMS Messaging

Hello Asterisk Community,

I am exploring ways to integrate Asterisk with SMSLocal for sending bulk SMS messages. My goal is to trigger SMS notifications based on call events, such as missed calls, IVR selections, or custom triggers within Asterisk.

Key Requirements:

  • Outbound SMS via API: Sending SMS through SMSLocal when a call event occurs.
  • Inbound SMS Handling: Capturing and processing incoming SMS responses.
  • Call & SMS Automation: Automating SMS alerts for missed calls or specific dial plan scenarios.
  • API & Webhook Support: Best practices for integrating SMSLocal’s API with Asterisk.

Questions:

  1. Has anyone successfully integrated Asterisk with SMSLocal or similar bulk SMS platforms?
  2. What’s the best way to trigger an SMS from extensions.conf or a custom Asterisk script?
  3. Are there recommended AGI scripts, dial plan configurations, or third-party modules for handling SMS via API?
  4. Any security considerations or rate-limiting factors when handling bulk SMS?

I appreciate any insights, examples, or recommendations from the community!

If you are sending to North American destinations, you need to register under the 10DLC rules. Their definition of “campaign” is very broad, and basically covers all business generated SMS.

There’s at least 24 different campaign types that cover various scenarios and needs. These categories limit what types of messages can be sent in association with it. It means a single business could end up with multiple campaigns due to the types of messages they are sending.
