Block Incoming Calls and Faxes | RingCentral Online Account
• When a number is added to the blocked numbers list, it blocks all incoming calls, faxes and text messages from that number.
• When Users block a number, it is only applied to the extension where they are logged in.
• If the Super Admin blocks a number while logged in to the System Extension (the main extension of the account), it is applied to all extensions in the account; which means that the blocked number is prevented from calling any number associated with the account.
The following behavior are observed when a number is added to a User's blocked list:
• The User/ Extension who added a number to its blocked list can still call and send faxes to a blocked number.
• The User/ Extension who added a number to its blocked list will be unable to send a text message to a blocked number and will get an error message Message not delivered. The recipient number is not valid.
• The blocked number will NOT get any message or indicator that the text message sent to the User/ Extension is blocked/not sent.
The option to block SMS or MMS ONLY is currently NOT available.
To request for the option to block SMS or MMS only, you can Submit a request for a new Idea or Feature via the RingCentral Community.
