Does the Zoom Slack app support Zoom Phone?

The standard Zoom for Slack app focuses on meetings (/zoom command). There's no native /zoom phone command. To get Zoom Phone notifications in Slack (missed calls, voicemails), use Zapier or a custom webhook integration.

Can I get Zoom Phone voicemail notifications in Slack?

Yes, using Zapier or a custom webhook. Set up a trigger on the 'phone.voicemail_received' event in Zoom, and post a formatted message to a Slack channel with caller name, number, voicemail duration, and a link to listen.

Can I route different phone notifications to different Slack channels?

Yes. In Zapier, add filter steps to route based on caller, queue, or extension. For example: sales line calls go to #sales-calls, support line calls go to #support-calls. With custom webhooks, add routing logic in your middleware.

What Zoom Phone events can trigger Slack notifications?

Common events: phone.voicemail_received (new voicemail), phone.caller_call_log_completed (call ended), phone.callee_missed (missed call). All are available via Zoom's webhook event subscriptions.

How to Get Zoom Phone Notifications in Slack

The Zoom app for Slack handles meetings (/zoom), but Zoom Phone notifications — missed calls, voicemails, completed calls — require a separate integration. This guide covers two approaches: a no-code Zapier setup and a custom webhook solution.

For the full Zoom + Slack integration, see the Complete Guide to Zoom and Slack.

Prerequisites

Zoom Phone license
Zoom app for Slack installed — see installation guide
Zapier account (for Option 1) or development resources (for Option 2)

Option 1: Zapier (No-Code)

Voicemail Notifications

Sign in to Zapier.
Click Create Zap.
Trigger: Search for Zoom > select New Voicemail.
Connect your Zoom account (requires admin-level OAuth).
Action: Search for Slack > select Send Channel Message.
Connect your Slack workspace.
Configure the message:

Field	Value
Channel	Select your notifications channel (e.g., #phone-notifications)
Message Text	`New voicemail from {{caller_name}} ({{caller_number}}) — {{duration}} seconds`
Bot Name	Zoom Phone
Bot Icon	Use a phone emoji or Zoom logo URL

Test and enable the Zap.

Missed Call Notifications

Create another Zap.
Trigger: Zoom > New Call Log (filter for missed calls).
Add a Filter step: result equals missed or no_answer.
Action: Slack > Send Channel Message.
Configure: Missed call from {{caller_name}} ({{caller_number}}) at {{start_time}}.

Channel Routing

Add filter steps to route different call types to different channels:

Condition	Slack Channel
Called number contains “sales”	#sales-calls
Called number contains “support”	#support-calls
Call queue = “Main Line”	#reception
After hours (time filter)	#after-hours-calls

Option 2: Custom Webhook Integration

For more control and no third-party dependency.

Step 1: Create a Slack Incoming Webhook

Go to your Slack workspace > Apps > Incoming WebHooks (or create a Slack app with incoming webhook capability).
Choose the channel for notifications.
Copy the webhook URL (e.g., https://hooks.slack.com/services/T.../B.../xxx).

Step 2: Create a Zoom Webhook App

Go to the Zoom App Marketplace > Develop > Build App.
Choose Webhook Only app type.
Under Event Subscriptions, add a subscription.
Subscribe to events:
- phone.voicemail_received — new voicemail
- phone.callee_missed — missed call
- phone.caller_call_log_completed — call completed
Set the Notification endpoint URL to your middleware (see Step 3).
Activate the app.

Step 3: Build Middleware

Create a small service (AWS Lambda, Google Cloud Function, Cloudflare Worker, etc.) that:

Receives the Zoom webhook payload
Extracts caller info, call type, duration, timestamp
Formats a Slack message block
Posts to the Slack incoming webhook URL

Key fields from Zoom webhook payload:

Field	Event	Description
`caller_name`	All	Caller display name
`caller_number`	All	Caller phone number
`callee_name`	All	Who was called
`callee_number`	All	Extension or number called
`duration`	voicemail, call_log	Duration in seconds
`start_time`	call_log	When the call started
`result`	call_log	`answered`, `missed`, `voicemail`, `no_answer`

Step 4: Format Slack Messages

Use Slack Block Kit for rich formatting:

Voicemail notification example:

Title: “New Voicemail”
Fields: From (name + number), To (extension), Duration, Received at
Action button: “Listen in Zoom” (link to Zoom Phone voicemail)

Missed call notification example:

Title: “Missed Call”
Fields: From (name + number), To (extension), Time
Action button: “Call Back” (zoom phone deep link)

Notification Types

Event	Use Case	Recommended Channel
Voicemail received	Alert team to new voicemails requiring callback	Team or individual DM
Missed call	Track missed calls for SLA monitoring	Team channel
Call completed	Log all call activity for reporting	Dedicated #call-log channel
After-hours call	Alert on-call team when calls come in outside business hours	#on-call channel

Common Issues

Zapier not triggering on Zoom Phone events — Zoom Phone webhook events require admin-level OAuth scopes. The Zoom account connected in Zapier must be an admin account, not a regular user account.
Duplicate notifications — If you have both Zapier and custom webhooks pointing to the same events, you’ll get duplicates. Use one approach, not both.
Caller name showing as “Unknown” — Zoom Phone may not have the caller’s name if they’re not in your contacts. The phone number will always be available. Consider adding a contact lookup step in your automation.
Notifications delayed — Zoom webhooks have a small delivery delay (usually seconds, occasionally up to a minute). Zapier adds its own polling interval on top of that. For near-real-time notifications, use the custom webhook approach.
Slack webhook URL stopped working — Slack incoming webhooks can be deactivated if the associated Slack app is removed or the channel is deleted. Verify the webhook is still active in your Slack app settings.
