RingCentral C#应用来电实时通知问题求助

Hey there! Let's troubleshoot why your incoming call notifications aren't coming through, even though SMS alerts work perfectly with the RingCentral C# library. Here are the key fixes and checks to try:

• Double-check your webhook subscription event filters
  SMS notifications rely on the /restapi/v1.0/account/~/extension/~/message-store event path, but incoming calls require different event endpoints. Make sure your subscription includes either:

  • /restapi/v1.0/account/~/extension/~/telephony/sessions (for real-time call session events)
  • /restapi/v1.0/account/~/extension/~/presence (if you want presence updates + call alerts)
    Here's an example of how to structure the subscription correctly:

  var subscription = rc.Restapi().Subscription().Create(
      new List<string> {
          "/restapi/v1.0/account/~/extension/~/telephony/sessions",
          "/restapi/v1.0/account/~/extension/~/message-store" // Keep your existing SMS event
      },
      (notification) => {
          // Handle incoming notifications here - make sure you check the event type!
          if (notification.EventUri.Contains("telephony/sessions")) {
              // Process call event logic
          } else if (notification.EventUri.Contains("message-store")) {
              // Process SMS logic
          }
      }
  );
  

• Verify app permissions in the RingCentral Admin Portal
  It’s common to have SMS permissions enabled but miss the ones required for call notifications. Log into your RingCentral admin console, navigate to your app, and ensure you’ve enabled:

  • Read Call Log
  • Read Presence (if using the presence event endpoint)
    After updating permissions, re-authorize your application to apply the changes.

• Ensure your webhook endpoint handles call event payloads correctly
  Even though SMS notifications reach your endpoint, call event payloads have a different structure. Check your callback code to make sure it’s not filtering out or failing to parse call-specific data. Also, confirm your endpoint is publicly accessible (no firewalls or local network blocking) and returns a 200 OK response to RingCentral’s POST requests—failed responses can lead to notification retries stopping.

• Test with the Sandbox environment
  Switch to the RingCentral Sandbox and use its built-in call simulation tools to trigger a test incoming call. This helps rule out production-specific configuration issues and lets you isolate whether the problem is in your code or environment setup.

• Check subscription renewal status
  RingCentral subscriptions expire after 7 days by default. Make sure your code enables automatic renewal to keep the subscription active:

  subscription.SetRenewal(true); // Enables auto-renewal
  await subscription.Register();
  

  You can also query the subscription status via the API to confirm it’s still active.

• Inspect webhook logs for errors
  If your endpoint has logging enabled, check if call notifications are even reaching it. Look for any 4xx/5xx response codes that might indicate why RingCentral isn’t delivering alerts consistently.
