# Phone Call Blasts Phone call blasts automatically call selected candidates. ## How Phone Call Blasts Work 1. **No message required** - Calls are initiated automatically by the system 2. **Recipients**: Only candidates with phone numbers from previous SMS engagement 3. **Filtering**: Option to only send to candidates who haven't completed interviews and aren't knocked out 4. **Automated process**: System handles all call initiation ## Rate Limiting Phone calls are rate limited to **once every 6 hours per candidate**. This prevents over-communication and maintains professional standards. * If you attempt to call a candidate who received a call in the last 6 hours, they will be automatically skipped * The system tracks this automatically - you don't need to manage it manually * Skipped candidates will show "rate\_limited" as the reason in your blast results ## Requirements * Phone numbers from candidates who've previously engaged via SMS * No message or content needed - calls are automated ## Technical Details * Only candidates with SMS history can receive phone calls * System automatically initiates calls * Invalid phone numbers are automatically skipped * Calls are made during business hours ## Viewing Phone Call Blast Results After initiating calls, you can view: * **Total selected**: Number of candidates you chose * **Eligible**: Candidates who met the filtering criteria and have SMS history * **Enqueued**: Successfully initiated calls * **Skipped**: Candidates who were filtered out (with reasons) Access blast history from your job posting's Actions dropdown → Blast Requests. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
