Definition
Outbound calling is when a business starts the call, phoning customers or prospects for sales, reminders, collections or surveys. A voice agent dials the number, waits for an answer, and then speaks.
How outbound calling works
The platform picks a number to call from and sends the call to a carrier, often over a SIP trunk. The carrier rings the recipient, and the call counts as answered when the recipient picks up. Before anything is said, the system has to decide whether a person or a voicemail answered, which is the job of answering machine detection. The agent then speaks, after the recipient has said hello.
Calls are placed one at a time, from a list in a batch, or paced by a predictive dialer. They differ in who limits the pace: a person, a number of free agents, or a concurrency cap.
Purposes differ and so do the rules. A reminder to a patient, a survey, a collections call and a sales call are treated differently. In the US, the Telemarketing Sales Rule at 16 CFR Part 310 covers telemarketing. It includes the national Do Not Call provisions, calling-time limits of 8:00 a.m. to 9:00 p.m. at the recipient’s location, abandoned-call limits, and caller ID transmission. The TCPA separately governs autodialed and artificial or prerecorded voice calls. Which rules apply depends on the call’s purpose and the number called.
Why it matters for voice agents
Outbound makes a voice agent speak to someone who did not ask to talk. That changes the first ten seconds. The agent has to say who it is and why it is calling quickly, because the recipient is deciding whether to hang up. It also has to handle the recipient answering with a name, a question or silence. The caller ID shown, and whether the call is flagged as spam, decide whether many calls are answered at all. Carriers vouch for the number by signing it under STIR/SHAKEN. An answered call is also not the same as reaching the intended person, which is what right-party contact counts.
Scale cuts both ways. An agent can dial thousands of numbers in an afternoon, which is also how a consent mistake reaches thousands of people. Check consent, the Do Not Call status of each number and the time zone before the campaign starts. This page is general information, not legal advice.
Example
An illustrative call: the agent dials a patient list for tomorrow’s appointments. On answer it waits for the recipient’s hello, says who is calling and for which clinic, and asks them to confirm or reschedule. If it hits voicemail, it leaves a short callback message or hangs up, depending on the campaign setup.
