Connect Zendesk to Dial800's AI Voice Agents and every support call gets answered — at 2 PM or 2 AM. The AI recognizes the caller, files a complete ticket, reads back status on existing ones, adds comments, and (only if you opt in) resolves tickets it has fully handled. A Zendesk AI phone agent that files the kind of tickets your team wishes humans wrote.
Five tools, each one enabled or disabled per agent — including a resolution tool that stays off until you say otherwise.
The agent matches the phone number to the requester (find_caller), so existing customers aren't treated like strangers.
The AI gathers the issue methodically and files it (create_support_ticket) with a complete description — product, symptom, urgency, contact details.
Callers get a live status readout (check_ticket_status) instead of “someone will get back to you.” Status calls stop consuming human time.
New information from the caller lands on the existing ticket (add_ticket_comment), keeping one thread instead of three duplicate tickets.
When the AI fully answers the caller's question, it can mark the ticket solved (resolve_ticket) — but only if you've explicitly enabled that tool.
A hypothetical overnight support call. No hold music, no callback queue — and the ticket your team finds in the morning is better documented than most tickets filed by hand.
Multiply this by every after-hours call, every status check, and every “just adding one thing” call, and tier-zero AI support becomes the quiet workhorse of your help desk.
“My service stopped working an hour ago and I have a deadline tomorrow.”
find_caller matches the number to the account. “I've found your account — let's get this documented right now.”
The agent asks what happened, when, and what the caller already tried — the questions a good tier-one agent asks.
create_support_ticket files a complete, prioritized ticket. The caller gets the ticket reference before hanging up.
If the caller rings back, check_ticket_status gives a live update and add_ticket_comment appends anything new — same ticket, one thread.
An OAuth client, per-tool allow-listing, and assignment to any agent you run.
Connect through a Zendesk OAuth client. Sign in, grant access, done — Dial800 manages the tokens from there.
Enable only the tools you want per agent. resolve_ticket stays off unless you deliberately turn it on.
Give your after-hours line the full support toolkit while a general reception agent gets lookup-only access — each agent has its own set.
