Zoom Phone Error Code 403 is a permission-style failure: your call request reaches the service, but something about account access or the calling entitlement blocks the call from completing.
What People Usually Notice With Zoom Phone 403
Most screens show Call failed with a longer code (for example, a 7-digit or 8-digit number). Zoom’s guidance is to read the last three digits as the actual error code, which is where 403 comes from. [✅Source-1]
If the message says your account is inactive or your call “can not be completed yet,” it usually points back to a Zoom Phone license, calling plan, or user activation state that needs an admin adjustment. [✅Source-2]
Common Text: “Your account is inactive”
Common Text: “Call can not be completed yet”

Identify The 403 You Are Seeing
Zoom Phone error popups often include a longer numeric value, but Zoom’s own guidance is to treat the last three digits as the actionable code. When the last three digits are 403, you are in the right troubleshooting lane. [✅Source-3]
| What You See | What It Usually Points To | First Place To Check |
|---|---|---|
| 403 + “Your account is inactive” | Zoom Phone access is not active for this user | Activation Status in the Zoom web portal |
| 403 + “Call can not be completed yet” | License or calling plan is missing or not assigned correctly | Zoom Phone license and outbound calling package |
| 403 after a plan or user change | A recent update removed permissions needed to place calls | Recent changes in Users & Rooms assignments |
What The Code Typically Means
At a protocol level, 403 is commonly used to express “forbidden”: the server understands the request but refuses to fulfill it, often due to insufficient authorization. That general meaning helps frame Zoom Phone 403 as an access or entitlement problem rather than a “bad number” problem. [✅Source-4]
Meaning In Zoom Phone
Zoom Phone uses 403 in its own error list to signal “account inactive” or a call that cannot be completed yet. The suggested remedy is to involve an admin who can adjust a Zoom Phone license or calling plan. [✅Source-5]
Why It Often Hits Outbound Calls
A key distinction: a calling plan permits outside calling. Zoom notes that without a calling plan, a user can only make inside, extension-to-extension calls. If your internal calls work but outside dialing fails, this is a strong signal. [✅Source-6]
Why It Can Say “Inactive”
Zoom Phone access can be activated or deactivated per user. Zoom’s admin guidance notes that deactivation prevents users from making calls, while activation restores access. That status is often the difference between normal calling and a 403. [✅Source-7]
Fix Steps For End Users
Goal: gather clear signals for your admin, while also ruling out simple client issues. Keep notes on the exact message text and the full code shown on screen.
Step-By-Step Checklist
- Retry once after 30–60 seconds. If it’s a temporary service condition, the next attempt may succeed without further action.
- Confirm you are signed in to the correct work account in Zoom, not a personal profile, and open the Phone tab.
- Place a short internal test call to a coworker’s extension. If extensions work but outside dialing fails, the issue often sits with a calling plan or outbound permissions.
- Try the same call from another Zoom Phone endpoint you already use (desktop app vs. mobile app). A consistent 403 across endpoints suggests an account-side block.
- Capture these details for your admin: the last three digits (403), the full numeric code, and the exact text (“inactive” vs “can not be completed yet”).
What To Ask Your Admin To Check
- Is my Zoom Phone access currently Activated?
- Do I have a Zoom Phone license assigned?
- Do I have an outbound calling package or calling plan assigned for outside dialing?
Zoom’s own guidance for the “call can not be completed yet” flavor of 403 explicitly points to a potential account license or calling plan problem that an admin can correct. [✅Source-8]
Fix Steps For Admins
Zoom Phone 403 is often resolved by restoring the user’s license, correcting their outbound calling package, or re-activating Zoom Phone access. The steps below follow the structure Zoom uses in Phone System Management.
Admin Checklist In Users & Rooms
- Open Phone System Management and go to Users & Rooms. Confirm the user appears as a phone user and has a Zoom Phone license.
- Check the user’s Activation Status. If it is deactivated (or not ready/active), switch it to Activated so the user can place calls again.
- Assign an outbound calling package to enable outside dialing where required. Then confirm and assign numbers as needed.
Zoom’s “Managing phone users” workflow shows how to assign licenses and then assign a calling package for outbound calling within Users & Rooms. [✅Source-9]
Direct Number And Number Assignment Notes
If the user needs a direct number (or you are standardizing caller ID), confirm the number is properly assigned and the user meets prerequisites. Zoom’s number management guidance ties number assignment back to having a Zoom Phone license, an extension, and a suitable calling package when numbers are involved. [✅Source-10]
Dial Plan And Outbound Routing Checks
If your organization uses different connectivity options, a 403 can surface when the call is routed through the wrong path for that user. Zoom’s dial plan guidance notes that outbound routing is determined by the package assigned to each user, and that Zoom implements the E.164 numbering plan to support a global dial plan architecture in relevant connectivity scenarios. [✅Source-11]
Practical Checks That Often Resolve Policy-Style Blocks
- Confirm the user’s outbound calling package matches the expected routing path for their assigned number and site.
- Standardize dialing strings where required using E.164 format (for example, full international format) so routing rules apply consistently.
- If calls work from one user but fail with 403 from another, compare their assigned packages and their outbound permissions.
Device And Client Checks
Even when a 403 is account-driven, endpoint issues can mask the true cause. Keep endpoint checks quick and focused, then return to license and activation if the signal stays consistent.
Desk Phones And Provisioned Devices
Zoom’s certified hardware guidance states that desk phones must support TLSv1.2 and should be on the latest firmware for reliable Zoom Phone operation. If a single device shows unusual behavior, validate firmware and compatibility early. [✅Source-12]
Device Assignment Limits And Hygiene
From an admin perspective, verify the endpoint is assigned to the correct user and isn’t stuck in a stale assignment. Zoom notes that each user can be assigned up to 3 phones or devices, which makes it realistic for old assignments to linger if they are not cleaned up. [✅Source-13]
When To Escalate
Escalation is appropriate when you have confirmed the user has a Zoom Phone license, an outbound calling plan or calling package, and an active status, yet the same 403 persists across multiple endpoints.
Information That Speeds Up Resolution
- The full error code shown (keep the whole number) and the last three digits (403).
- The exact error text (“account inactive” vs “call can not be completed yet”).
- Timestamp, device type (desktop, mobile, desk phone), and whether the call was internal (extension) or external.
- What changed recently: license assignments, packages, activation status, device assignments, or dialing rules.
For privacy, share call details only through your organization’s normal support channels. Avoid posting full phone numbers in public places, even when troubleshooting a 403.
FAQ
Is Zoom Phone Error Code 403 Always A License Problem?
Most Zoom Phone 403 cases map to access or entitlement. If you can call internal extensions but not outside numbers, the gap is often a calling plan or outbound package. If you cannot place any calls, check Activation Status first.
I See “Your Account Is Inactive.” What Does That Mean In Practice?
It usually means Zoom Phone access is not active for that user right now. An admin can switch the user back to an Activated state so calling works again, then confirm the user’s license and calling permissions.
Why Can I Call Internal Extensions But Not External Numbers?
Zoom explains that a calling plan permits outside calling, while without a calling plan a user can be limited to extension-to-extension calls. That pattern is one of the clearest signals for this issue.
Do I Need To Reinstall Zoom To Fix 403?
Reinstalling rarely fixes a true 403 on its own because the most common causes are account-side. It can still be useful as a final endpoint step when you suspect a corrupted client state, but keep focus on license and activation first.
Can Dialing Format Trigger A 403 In Some Environments?
Yes, in setups where routing depends on a consistent dial plan, using standardized formats (commonly E.164) helps the system apply the correct route and permissions. That matters most when outbound routing is driven by the user’s package and connectivity configuration.
Does Desk Phone Firmware Matter For 403?
Firmware and compatibility are not the usual root cause of 403, but they can create confusing edge cases when one device behaves differently than others. Keeping devices compatible (including TLS support) and current reduces false signals while you validate license and activation.
