One AI. Three playbooks.
Della detects who's calling, qualified lead, existing client, or unknown/spam, and runs the right playbook. Qualified leads get qualified. Existing clients get routed. Spam gets filtered. You set the rules.

Treating every caller the same is treating most of them wrong.
A new prospect needs intake. A returning client needs to be heard fast. A robocall needs to be hung up on. Treating all three the same means slow service for clients, friction for leads, and wasted minutes on spam.
Della runs three default playbooks based on caller type. Qualified leads get a 3-6 question qualification flow tuned to your vertical. Existing clients (matched by caller-ID) get the fast lane: greeting by name, last visit pulled, warm transfer or quick reschedule. Unknown/spam gets verification → message-or-block. Each playbook is fully customizable.
What Della does on the call.
Qualified Leads playbook
3-6 vertical-specific qualification questions, then booking or escalation. Tuned per vertical (matter type for legal, service preference for salon).
Existing Clients playbook
Caller-ID match → greeting by name → last visit pulled → fast lane to booking, reschedule, or warm transfer.
Unknown/Spam playbook
Voice verification on suspicious numbers; message-taking for legitimate inquiries; auto-block for confirmed spam.
Custom playbooks
Add caller categories beyond the defaults: VIP clients, partners, vendors, after-hours-only callers. Each gets its own flow.
Caller tagging
Tag specific numbers with custom categories. Della runs the matching playbook automatically.
A/B test playbooks
Pro tier: split traffic between playbook variations. Test which qualification flow converts better. Della tracks the results.
Call from your phone and try it: book a time, ask a question, switch languages. She tells you she is an automated assistant, then does the job.

Common questions.
Still unsure? Call Della at +1 (818) 918-4562 and ask her.
How does Della detect caller type?
Caller-ID match against your client database (existing client), spam database lookup (spam), default to qualified-lead playbook for everyone else. Custom rules can override.
Can the playbook change mid-call?
Yes. If a caller starts as 'unknown' and self-identifies as an existing client, Della verifies and switches playbooks seamlessly.
Can I see which playbook ran for each call?
Yes, every transcript shows the playbook that ran and the trace of decisions Della made. Useful for tuning.
