Zendesk AI Phone Agent: Zendesk Voice AI or a Store Voice Agent

A Zendesk store can add an AI phone agent in two main ways: Zendesk's own voice AI agent on a Zendesk voice line, or a store voice agent that answers on its own number and passes the calls it cannot resolve to your team, live in support hours or as a Zendesk ticket. The deciding question is whether the agent must read your Shopify orders and also make outbound calls: if so, pick a store agent; if your phones already run on Zendesk voice and most calls are policy questions, Zendesk's agent is simpler.

Loop Voice publishes this page and is one of the store agents; the Zendesk details come from Zendesk's pricing page and Help Center, as of October 2026.

Zendesk Voice, formerly Talk, is Zendesk's phone channel; its native voice AI agents became generally available on September 1, 2026 (Zendesk announcement). The agent picks up every call to its line, and each call creates or updates a ticket. Resolved calls end with the transcript, an AI summary and the recording on the ticket; unresolved ones go to your phone queue with the transcript and summary, or to voicemail if nobody is free (About voice AI agents).

It answers from your help center and other knowledge sources, runs actions such as API calls, SMS messages and ticket updates, and handles 53 languages (Zendesk). It is not available with Talk Partner Edition, and Zendesk Contact Center support is planned for a future release.

Voice AI agents need Zendesk voice: any Suite plan, or a Support plan with a Talk plan (Zendesk). AI agents come with every Suite and Support plan and are billed per automated resolution (Zendesk pricing):

The last two rows are from Zendesk's Talk pricing article; minutes and numbers cost extra (a US local number is $1 a month).

A newer model, resolution tiers, started on May 18, 2026: only calls that an LLM verifies as resolved draw on your plan's allowance, and escalated calls do not (resolution tiers). Under it, plans include a dollar allowance instead: $2 per agent seat a month on Suite Team and $5 on Suite Professional (resolution allowances). Ask Zendesk which model your account is on.

Zendesk's agent can use Shopify order data, but you set up the connection. Since June 2026 its AI agents can run action flows, which Zendesk now recommends over API integrations (Zendesk), and on September 3, 2026 it added order search and lookup actions to its Shopify connector, rolling out to accounts with access to action flows (Zendesk). Check which of those actions your plan includes before you count on them. The older route is a custom API request, which Zendesk says it can't support for third-party APIs or Shopify (Zendesk).

Loop Voice's inbound agent answers 24/7 and handles order status, returns and exchanges, sizing, shipping and subscription changes (customer support use case). It looks up the order and gives its status; installing the Loop Voice Shopify app connects the store, so there is no lookup to build.

Loop Voice also makes outbound calls for checkout recovery, upsells and win-back, and a customer it called this week who calls back gets the same agent, mid-conversation (features).

When it cannot resolve a call during your support hours, it can transfer the caller to your team's number, briefing the teammate first; if nobody answers, or outside those hours, it creates a ticket in Loop Voice and in Zendesk with the AI summary, the order and the recording. Rules stop or escalate on negative sentiment, a do-not-contact request, complex refunds, and legal or medical questions.

It answers on your Twilio number, a number bought in 90+ countries, or a SIP trunk from Twilio, Vonage or Telnyx; to cover only evenings and weekends, forward your store line to it in those hours.

The connection is an OAuth client: one form in Zendesk, one in Loop Voice.

1. In Zendesk Admin Center, click Apps and integrations, then APIs, then OAuth clients, and click Add OAuth client (Zendesk OAuth guide). Loop Voice's settings page may still show an older path (APIs, Zendesk API, OAuth Clients tab).
2. Name it, for example "Loop Voice", keep or edit the identifier Zendesk fills in from the name (this is your Client ID), and set Client kind to Confidential: Loop Voice uses the client secret, and Zendesk requires public clients to use PKCE.
3. Under Redirect URLs, paste the redirect URL shown on Loop Voice's Zendesk settings page.
4. Save, copy the secret at once (Zendesk shows it in full only once), then click Save again.
5. In Loop Voice, open Settings, Integrations, Zendesk, enter your subdomain (the part before .zendesk.com), the Client ID and the secret, then click Connect Zendesk and authorize Loop Voice in Zendesk.

Each handoff ticket carries the AI summary, the transcript, the order and the recording, so nobody asks the customer to start over. Loop Voice keeps recordings for 7 days by default; extend that to 90 days if your team reviews calls more than a week later, or switch recording off per number.

Make a test call that ends in a handoff and note what marks the ticket in Zendesk, such as a tag or the subject line. Match on it in a trigger, since Zendesk's views guide asks for a condition on a field such as status or group and lists tag and text checks among conditions to avoid (Zendesk views).

1. Trigger: Admin Center, Objects and rules, Business rules, Triggers. When a ticket is created with the marker, set the group that follows up on phone handoffs and notify it (Zendesk triggers).
2. View: Admin Center, Workspaces, Agent tools, Views, Create view, with "Group is" that team and "Status is less than Solved" (Status category on newer accounts).

Our support setup guide covers the rest of the helpdesk setup.

Set the scope before the first live call:

Medical questions are the row to rehearse. A caller nine months out from knee surgery asked a health device brand's agent whether its product was safe for them:

The agent quoted the store's safety guidance, refused to override it, pointed them to their physical therapist or surgeon, and texted a 10% code. Load your safety pages into the knowledge base and decide whether such calls end in a careful answer or a ticket; the call library has more real calls, mostly outbound.

Run the simulator first: six personas, including an angry customer and someone suspicious of AI, up to ten conversations per run, with nothing dialed and no credits used (features). Then:

1. In the test console, enter your number and a scenario, such as a jacket in the wrong size; the agent calls you.
2. Call the agent's number and ask "Am I talking to a robot?" With the guardrail for clear identity as an AI when asked turned on, it says it is an AI.
3. End one call with a handoff: ask for a refund outside policy, or for a person.
4. In Zendesk, check that ticket's summary, transcript, order and recording, the group the trigger set, and your view.
5. After a week, read the answer gaps (live questions that found nothing, over 7, 30 or 90 days) and run the retrieval test on each.

Setting up your first agent covers the rest.

Zendesk charges per call its AI resolves, plus minutes; Loop Voice charges per answered conversation, resolved or handed off, at about 1.5 credits each (pricing).

Example, at the pricing page's rates: a store with three agents on Suite Team gets 330 calls a month, about four minutes each. The AI resolves 200 and hands off 130.

The Zendesk column leaves out seats, inbound call minutes and number fees, and a busier month would push Loop Voice past Growth's 500 credits into extra credits. Against Growth billed monthly, Zendesk costs less here; against Growth billed yearly ($319), it costs less on committed prices ($288.06) and more on pay-as-you-go ($380.56). Its bill grows with each resolution: it passes Growth billed monthly at about 210 resolved calls (64%) on pay-as-you-go or 274 (83%) on committed prices, and Growth billed yearly at about 170 (52%) or 221 (67%).

Zendesk's pricing page offers telephony from Suite Team, $36 more per agent a month billed yearly than Support Team. Our AI vs call center comparison adds staffing costs.

Choose Zendesk's agent when most of these hold:

• Your phones run on Zendesk voice and your team takes escalated calls in Zendesk's own phone queue.
• Your help center answers most calls.
• Someone can set up and maintain a Shopify order lookup in Zendesk.
• You need more languages than Loop Voice's English, Spanish and 30 more; Zendesk lists 53.
• You want AI fees only on resolved calls (minutes, AI connection and recording apply to every call).

Choose a store agent like Loop Voice when it must look up orders from day one, should also call shoppers about checkouts, upsells and win-back, or your phones are not on Zendesk voice, including Talk Partner Edition. To compare store agents, see the best AI phone agents for Shopify customer service.
