Zapier VoIP: Automate Calls, Logs, and Alerts with Workflow Tools

When you use Zapier VoIP, a way to connect your VoIP phone system to other apps using automated workflows. Also known as VoIP automation, it lets you trigger actions like logging calls in Salesforce, sending SMS after a missed call, or updating a spreadsheet every time someone hangs up—without touching a single line of code. Most small businesses and remote teams don’t realize how much time they waste manually entering call data, chasing follow-ups, or switching between apps. Zapier fixes that by turning your VoIP system into a hub that talks to your CRM, email, project tools, and more.

It works with popular VoIP platforms like OpenPhone VoIP, a cloud-based business phone system for teams that handles calls and texts in one app, Microsoft Teams, a unified communications tool that includes calling, meetings, and chat, and even SIP-based systems through webhooks. You can set up triggers like "Call ends" or "New voicemail" and connect them to actions like "Create a task in Trello," "Add a contact to Mailchimp," or "Send a Slack alert to the sales team." This isn’t just convenience—it’s how you stop losing leads, reduce admin work, and keep your data accurate across systems.

Think about a customer service rep who gets 50 calls a day. Without automation, they’re spending 15 minutes after each call typing notes into a CRM. With Zapier VoIP, that’s done in 3 seconds. Or imagine a sales team that misses follow-ups because calls aren’t logged. Zapier ensures every call is recorded in your pipeline, even if the rep forgets. And if you use call tagging, a method to label call outcomes like "interested," "follow-up," or "closed" in VoIP systems, you can trigger different workflows based on those tags—like sending a discount code to leads tagged "interested" or flagging complaints to management.

Most guides focus on VoIP hardware or codec settings, but the real power today is in how your phone system connects to the rest of your tech stack. That’s where Zapier VoIP shines. Below, you’ll find real setups, common mistakes to avoid, and which VoIP tools work best with automation—so you can stop doing busywork and start focusing on what actually moves the needle.
