What it is
When a call goes unanswered, the caller automatically receives a text (or WhatsApp message) within seconds, so they are not left wondering whether to try the next business. A person or an AI assistant then continues the conversation by message.
When to send it
- Calls that ring out or go to voicemail during opening hours.
- All calls outside opening hours.
- Not for calls from numbers you have blocked, internal numbers, or very short accidental calls if your system can detect them.

Rules that keep it helpful
- Send fast: within a minute, or it feels random.
- Say who you are in the first words.
- Ask one simple question, or give one link. Not both plus a menu.
- Stop if they call back or reply, and alert a person.
- Do not add marketing. It is a reply to someone who contacted you, not a promotion.
- Respect opt-outs and keep a record.
Setup options

|---|---|

| Call tracking or VoIP provider with automation | Ties calls to sources and the CRM |
| CRM with telephony integration | Best for logging and follow-up |
| AI assistant on SMS or WhatsApp | Continues the conversation and books |
