Make Zendesk Work Harder: How Click-to-Call Transforms Support Efficiency

Click-to-call in Zendesk solves that problem directly. It turns every phone number inside a ticket, lead, or contact profile into an instant call button, so agents can launch calls without copying, pasting, or toggling to another platform. It eliminates friction at the exact point where speed matters most: right before an agent connects with a customer.

This functionality exists in two main ways within Zendesk: natively through Zendesk Talk, or via CTI integrations like Voiso. Each route allows agents to initiate calls from Zendesk Support or Zendesk Sell, while keeping call logs, notes, and recordings tied to the right customer record.

Click-to-call helps teams tackle time-sensitive support escalations, handle complex follow-ups faster, and create a clear call history for every interaction. If agents are spending too much time on busywork instead of resolving issues — this is where you take that time back.

Let’s break down how click-to-call works inside Zendesk, which setup options make sense for different teams, and how to get started in just a few steps.

What is click-to-call in Zendesk?

Click-to-call inside Zendesk is, at its core, a workflow upgrade. For support and sales agents, it means placing a call directly from a ticket, lead, or customer profile with one click. No more copying numbers. No switching tabs. Just click, connect, and talk — while Zendesk takes care of the background logging.

In Zendesk Support, this means clicking a customer’s phone number from within an open ticket. In Zendesk Sell, it happens inside a lead or contact view. Either way, the action is the same: click the number, launch the call, and let the system auto-link the interaction to the correct record.

There are two ways to enable this functionality:

• Zendesk Talk, the platform’s built-in telephony system, provides basic voice support and lets agents call directly from tickets. It works well for teams that only need voice and already use Zendesk for everything else.
• CTI integrations, like Voiso, go beyond the basics. They bring advanced features such as AI-powered call summaries, automatic transcription, multi-region voice routing, and richer analytics. These options are often preferred by global support centers or sales teams who need speed, context, and scale.

Click-to-call shines in daily moments where timing is critical — like calling back a missed customer, jumping on a priority escalation, or following up with a user who didn’t reply via chat or email. It cuts down the time between reading a ticket and acting on it, turning “I’ll get to this” into “handled.”

Zendesk talk vs. Third-party CTI: a quick comparison

Zendesk offers two primary ways to enable click-to-call, each suited to different needs and operational complexity.

How to set up click-to-call in Zendesk (step-by-step guide)

Once you’ve chosen your setup — Zendesk Talk or a CTI integration — getting click-to-call running is straightforward. Here’s how to go from zero to fully functional in five clear steps.

Step 1: confirm your Zendesk plan and telephony access

Before anything else, check if your Zendesk subscription includes telephony support.

• Zendesk Talk is available on Suite Team plans and above, but advanced features like IVR, call recording, and real-time dashboards require Professional or Enterprise tiers.
• To confirm your plan and available Talk features, navigate to Admin Center → Billing → Subscription.

If you’re using a third-party provider, like Voiso, plan tier matters less — but you’ll still need app installation permissions for integrations.

Step 2: connect your calling provider or integration

There are two setup paths depending on your tool of choice:

• Zendesk Talk: Go to Admin Center → Channels → Talk and email → Talk. Choose a number or request a new one, then enable calling.
• Voiso or other CTI: Visit the Zendesk Marketplace, search for your provider (e.g., Voiso), and click Install.

After installation:

• Log in to your Voiso account.
• Go to Settings → Integrations and authorize Zendesk access.
• Provide API credentials and configure permission scopes for call control, ticket access, and logging.

Third-party setups typically take just a few minutes and don’t require custom development.

Step 3: add agents and assign numbers

Once your telephony is connected:

• Assign direct lines or shared numbers to agents via the Talk dashboard or your provider’s admin panel.
• For outbound calls, agents must have roles with call permissions enabled.
  In Zendesk: Admin Center → People → Team Members → Edit Role and check “Make outbound calls.”
• Set routing rules for inbound queues (e.g., sales, support), if using IVR or advanced flows.

Step 4: test click-to-call from a ticket or user profile

Now, test the full workflow.

1. Open a Zendesk ticket or customer profile that includes a phone number.
2. Click the number — it should launch your call interface (Zendesk Talk panel or Voiso softphone).
3. During the call, confirm that:
   • The timer starts.
   • Audio connects.
   • The call is visible in the ticket interface.
4. After the call ends, the ticket should automatically update with the call record.

If you’re using Voiso, agents can also see screen pops with caller info and take notes during the call.

Step 5: enable automatic call logging

For every call to count, logging needs to be automatic.

• Zendesk Talk logs call duration, voicemail, and disposition by default.
• Voiso and similar tools allow deeper automation:
  • Auto-log outcomes like “successful,” “callback needed,” or “left voicemail.”
  • Sync call notes, recordings, and tags to the ticket or lead in real time.
  • Use disposition codes for reporting and follow-up triggers.

Set these under Settings → Call Dispositions or Workflow Rules, depending on the integration.

How click-to-call transforms support efficiency

Click-to-call is about changing how teams interact with customers, manage time, and measure outcomes. Once live, it starts removing small barriers that used to slow down agents, while creating opportunities to improve the entire support workflow.

Faster resolution times

Every second between reading a ticket and placing a call is lost momentum. Click-to-call eliminates that delay. Instead of switching tools or manually dialing, agents can launch the call instantly from the ticket itself.

This matters most in follow-ups and escalations — moments when waiting means risk. If a customer requests a callback or an issue needs urgent clarification, the agent clicks and connects right away. No number copying. No screen switching. Just action.

Before: Agents copy a number, open a softphone, start dialing.
After: Agent clicks the number in Zendesk, call starts immediately, resolution begins faster.

Unified ticketing and communication history

Click-to-call speeds things up and keeps everything in one place. Every call, whether inbound or outbound, is linked to its related ticket or lead. Recordings, notes, outcomes, and call durations appear alongside the message history and previous interactions.

This unified view means:

• No manual note-taking after the call.
• No digging through call logs to find out what was said.
• Clear visibility across team shifts, handovers, and escalations.

If you’re using a CTI like Voiso, this gets even better — with real-time call scoring, searchable transcripts, and sentiment indicators all attached to the correct ticket automatically.

Enhanced agent focus and reduced errors

Click-to-call helps agents stay in flow. They don’t need to bounce between platforms to manage conversations. Calls happen inside Zendesk, and all the relevant context — past tickets, notes, customer data — is already in view.

This means fewer mistakes, more accurate resolutions, and shorter average handle times (AHT). Agents can move from ticket to call to resolution without breaking focus.

Troubleshooting and Common Issues

Even with a smooth setup, small technical hiccups can disrupt click-to-call in Zendesk. Below are the most common issues teams run into, and how to solve them quickly.

Click-to-call button missing in ticket view

Fix: Make sure the number field is properly formatted (e.g., includes country code) and the integration app is active. If using a third-party CTI, confirm the browser extension or widget is loaded correctly.

Calls not logging or attaching to the correct ticket

Fix: Check that the integration has permission to access ticket and user data in Zendesk. Also confirm that the call was launched from within the ticket and not from an external dialer.

Browser permissions blocking call window

Fix: Ensure your browser allows microphone access and pop-ups for your Zendesk domain. If you’re using Chrome, go to Settings → Privacy and security → Site Settings and adjust permissions manually.

Audio or network instability issues

Fix: Use a wired internet connection when possible, and make sure agents aren’t on overloaded Wi-Fi networks. For CTIs like Voiso, verify the recommended browser and audio settings to reduce jitter and packet loss.

Agent permission errors

Fix: Review agent roles in Zendesk Admin Center and confirm they have outbound call privileges. For third-party tools, make sure their VoIP account or user profile is assigned the correct role within the provider’s admin panel.

Best practices for managing calls in Zendesk

Once click-to-call is live, the real value comes from how you manage and optimize it over time. These best practices help support leads and admins ensure that every call contributes to faster resolutions, cleaner data, and better overall performance.

Train agents to use standardized notes and tags

Consistency is key when reviewing call history or analyzing trends. Teach agents to log outcomes using predefined note templates and standardized tags (e.g., “callback requested,” “issue escalated”). This not only keeps ticket records clean but also makes reporting far more actionable.

Monitor call metrics regularly

Whether you’re using Zendesk Talk or a CTI, set a cadence for reviewing call data. Zendesk Talk dashboards offer visibility into metrics like average wait time and talk time, while CTI platforms provide deeper insight — such as agent performance scores, call topic trends, or silence ratios.

Set automation rules for missed calls

Don’t let missed opportunities fall through the cracks. Use Zendesk’s automation tools to trigger follow-up tasks or ticket updates when a call goes unanswered. For example, you can create a rule that flags any missed call without agent notes and routes it to a callback queue.

Link call data to CSAT reports

Calls are often the last touchpoint before a CSAT survey. By correlating call duration, resolution type, or disposition codes with satisfaction scores, you can start spotting patterns — like which call types lead to higher ratings or which agents drive the best outcomes.

Run scheduled quality reviews

Set up regular reviews using call recordings and AI summaries. Tools like Voiso generate auto-tagged summaries and sentiment scores, making it easier for supervisors to scan key moments without listening to every second. Pair this with agent coaching to improve accuracy, tone, and resolution quality over time.

Final thoughts — bringing voice and support together in Zendesk

Click-to-call streamlines phone conversations while reshaping how support teams work inside Zendesk. By eliminating manual dialing, centralizing interaction data, and accelerating agent response time, it helps teams resolve tickets faster without compromising on quality or context.

But setup is just the beginning. The real payoff comes from how you build on that foundation — with analytics, automation, and AI-driven tools that keep your support operation sharp, even as ticket volumes grow.

For teams ready to go beyond the basics, Voiso’s Zendesk integration brings everything together: seamless click-to-call, automatic call logging, real-time summaries, and conversation intelligence, all inside the Zendesk interface.
