Call Blocking Feature - Block Unwanted Calls

VoIPBusiness allows you to block unwanted calls by filtering and selecting who can call you or send you a fax. It also helps you with preventing the spam messages.


You can block certain contacts by creating a block list, all the contacts in the block list won’t be able to call you or send a fax. You can configure your VoIP Business online account to block unwanted calls and faxes from certain numbers, area codes, and phones that have no caller ID, faxes, and payphones.

When a contact is added to the block list, it blocks all incoming calls, faxes and text messages from that number. When you block a contact, it is only applied to the extension where they are logged in.

If the Admin blocks a number while logged in to the System Extension (the main extension of the account), then it will be applied to all the extensions listed in the account; which means that the number which has been blocked is prevented from calling any number connected with the account.
