🚫Blocked Numbers
Blocked numbers let you prevent specific phone numbers from calling your tracking numbers. When a blocked number calls, it is silently rejected — no ring, no charge, no call log clutter.
Blocked numbers are available on all plans (Indie and Agency). There is no limit on how many numbers you can block.
How It Works
When someone calls your tracking number, Ring Tonic checks the block list before connecting the call. If the caller is blocked, the call is instantly rejected and logged as a blocked attempt. The caller hears nothing — no ringing, no voicemail.
Blocked calls:
Do not appear in your call logs
Do not count toward your call usage
Are logged separately as blocked attempts (retained for 90 days)
Trigger a
call.blockedwebhook if configured
Two-Tier Block Lists
Ring Tonic supports two levels of blocking:
Workspace
Blocks a number in the current workspace only
Any workspace member
Account
Blocks a number across all your workspaces
Workspace owner only
The Account Block List tab only appears if you own more than one workspace. If you have a single workspace, only the workspace-level list is shown.
When a call comes in, Ring Tonic checks both lists. If the caller appears on either the workspace block list or the account block list, the call is rejected.

Blocking from Call Logs
You can block a caller directly from the call logs table without navigating to the Blocked Numbers page.
Find the call in your call logs
Click the row actions menu (three dots)
Select Block Caller
The block dialog opens pre-filled with the caller's phone number
When blocking from a spam-filtered call, the reason is automatically pre-selected as "Spam" to save you time. You can also toggle Mark as Junk to clean up all pending calls from that number at the same time.
Importing Blocked Numbers
If you have a list of numbers to block, you can import them in bulk via CSV.
Download the Template
Click Import CSV on the Blocked Numbers page, then click Download template to get a pre-formatted CSV file.
The template has three columns:
Fill In Your Numbers
phone_number (required) — The number to block in E.164 format
reason (optional) — One of:
spam,harassment,wrong_number,telemarketer,competitor,other. Defaults tootherif left blank.note (optional) — Free-text note, up to 500 characters
Upload the File
Click Import CSV, select your file, and click Import. Ring Tonic will process the file and report:
How many numbers were imported
How many duplicates were skipped
Any rows with errors
The CSV file must be under 2MB. Duplicate numbers (already on the block list) are automatically skipped.
Exporting Blocked Numbers
You can export your blocked numbers list to Excel or CSV.
On the Blocked Numbers page, click the Export button in the table toolbar
Choose Export to Excel (.xlsx) or Export to CSV (.csv)
The export is processed in the background — you'll receive an email with a download link when it's ready
The export includes: phone number, reason, note, blocked by, and date blocked.
Viewing Blocked Call Attempts
Click any row in the blocked numbers table to open the Blocked Call Attempts panel. This shows a timeline of every call attempt from that number in the last 90 days, including:
Date and time of each blocked call
Tracking number that was called
Campaign associated with the tracking number
Caller name (if available)
Caller location (city and state)
Block list type — whether the call was blocked by the workspace or account list
Blocked call attempt records are retained for 90 days. Older records are automatically purged.
Unblocking a Number
To remove a number from the block list:
Find the number in the blocked numbers table
Click the Unblock button (shield icon) on the row
Confirm by clicking Unblock in the confirmation dialog
The number will immediately be able to call your tracking numbers again. Future calls from that number will be processed normally and appear in your call logs.
Permissions: Only workspace owners and admins can unblock numbers from the workspace list. Only the workspace owner can unblock numbers from the account list.
Outbound Call Blocking
Blocked numbers also affect outbound calls made through the browser dialer. If an agent tries to dial a blocked number, the call will be prevented and an error message is shown with the block reason.
Webhooks
If you have webhooks configured, Ring Tonic fires a call.blocked event whenever a blocked call is rejected. This is useful for tracking blocked call volume in external systems.
Common Questions
Does blocking a number cost anything?
No. Blocked calls are silently rejected before the call connects, so there is no Twilio charge and no impact on your call usage.
Will the blocked caller hear anything?
No. The call is silently rejected. The caller will not hear ringing, a busy signal, or a voicemail greeting.
Can I block area codes or patterns?
Not currently. Blocking is per individual phone number. Area code and pattern-based blocking may be added in a future update.
What happens if a number is on both the workspace and account block lists?
The call is blocked either way. Unblocking from one list does not affect the other — the number must be removed from both lists to allow calls through.
