How to block a phone number

You can block phone numbers to automatically filter out unwanted or suspicious incoming calls and messages, such as spam or scam attempts.

Blocked numbers apply company-wide. When someone tries to reach your DialLink workspace from a blocked number, the call or message is automatically rejected.

How it works

  • The block list applies to incoming calls and messages across the entire workspace. When a blocked number tries to reach any user, DialLink automatically rejects the call or message before it is delivered.

  • Blocked calls never ring. They are silently dropped and appear in the call log with the relevant status, so users are not distracted by spam or repeated unwanted calls.

  • Blocked messages are filtered out entirely and do not appear in any chat thread or get delivered to any recipient.

  • Changes take effect instantly. Once a number is added or removed from the block list, the new rule applies to all users immediately.
