How to Diagnose and Fix Missing Twilio Call Events in HighLevel

When outbound dialing campaigns or automated phone sequences stall without clear error messages, the issue often stems from broken call event delivery between Twilio and your CRM environment. If call activities fail to log, downstream workflows—such as pipeline updates, follow-up text triggers, and disposition tagging—will cease functioning entirely.

Diagnosing this breakdown requires moving beyond the primary CRM interface and auditing the raw event logs generated at the telephony provider level. By systematically matching account identifiers and reviewing call payloads, you can pinpoint whether the issue is caused by misconfigured webhooks, authentication failures, or transient network timeouts.

Identifying the Target Subaccount ID

Because large agency accounts often manage dozens or hundreds of sub-accounts, locating the specific client workspace in Twilio by name alone can lead to errors. The most reliable method is to pull the unique Account SID directly from your agency settings.

1. Open your agency administrative portal and navigate to the phone integration management tab.
2. Search for the specific sub-account or location experiencing missing call records.
3. Copy the alphanumeric string labeled Account SID associated with that location.

This Account SID acts as the definitive identifier for all API requests and webhook callbacks generated by that specific location's phone number pool.

Navigating the Twilio Console

Once you have copied the correct identifier, you must switch into that specific subaccount context within the provider console. Performing diagnostics in the parent account will yield empty logs or irrelevant telemetry.

• Log into the main admin dashboard for your phone provider account.
• Locate the account selector dropdown in the upper navigation panel and select the subaccounts view.
• Paste the copied Account SID into the search field and select the matching subaccount entry.
• Verify that the active workspace header reflects the target subaccount before proceeding.

Auditing Call Logs and Diagnostic Telemetry

With the correct subaccount context active, you can inspect the real-time event logs to observe how outbound and inbound voice calls are processed.

Navigate to the Monitor section in the left navigation bar, expand the Logs menu, and select Calls. This view displays every call attempt made through the assigned phone numbers, along with timestamps, durations, operational statuses, and associated API response codes.

• Filter the log view by the specific date range and time window when missing calls occurred.
• Click directly on any call entry marked with a non-zero status code or an orange warning indicator.
• Inspect the request inspector panel at the bottom of the detail page to verify whether status callbacks were dispatched to the CRM endpoint.
• Check the HTTP response status returned by the receiving server. A 200 OK confirms delivery, whereas 4xx or 5xx codes indicate authorization errors or server failure.

Resolving Frequent Webhook and Event Failures

When status callbacks fail to reach your CRM, the issue usually falls into one of three categories: stale authorization tokens, missing webhook URLs on phone number configurations, or temporary API rate limits.

If the logs reveal 401 or 403 HTTP response errors, the authentication token connecting the two platforms has expired or been altered. Re-authenticating the phone provider connection inside your agency dashboard will issue a fresh token and restore webhook acceptance.

If call logs show a complete absence of records within Twilio itself, the issue lies upstream—such as browser permission blocks or dialer client connectivity—rather than webhook failure. Confirming the exact point of failure prevents wasting time reconfiguring working integrations.
