Usage with Calls

Once you’ve created a custom dialing pool, you can use it in your call requests by specifying the custom_dialing parameter: 
{
  "phone_number": "+12345678901",
  "task": "Your call task here",
  "custom_dialing": "550e8400-e29b-41d4-a716-446655440001"
}
The system will automatically select the most geographically appropriate phone number from your pool to maximize pickup rates.
