How to block calls from blacklisted contacts

Block calls via Dialplan

Step 1. Phonebook configuration

You can add blacklisted contacts to your phonebooks in different modes: from Legacy Collaboration, from the imported backend (MySQL, сsv, etc). Here it is described how to add a contact in Legacy Collaboration. 

• Go to Legacy Collaboration -> Phonebook 

• Select the desired phonebook and press + to add a new contact

• Set blacklist as a Type of contact

Open

Step 2. Dialplan configuration

• Create a separate Dialplan procedure for managing calls from blacklisted contacts

• Configure the behavior of managing these calls. For example, add Hangup application 

Open

• Go to Dialplan procedure used for managing incoming calls ("main" procedure)

• Add the applications to check if a call is from a blacklisted contact:

  • Jump to if call type is -> blacklist -> route calls to the previously created Dialplan procedure for blacklisted calls - if a call is from a blacklisted contact, it is dropped

  • Call group -> if it is a normal call, it is routed to a Call group

Alternative Way. Block calls via tagging in Phonebooks and Dialplan

Step 1. Create a dedicated phonebook with blocked users

To define a contact as blacklisted, add [blocked] tag to its name. Detailed information about how to create phonebooks and contacts can be found in Legacy Collaboration User Guide.

Step 2. Configure Dialplan

Modify Dialplan procedure used for managing incoming calls by adding Dialplan applications:

• Verify caller -> [blocked] -> Blocked procedure - If caller name contains [blocked] tag, a call is routed to Dialplan procedure created for managing calls from blocked users ("Blocked" in the example)

• Dial the phone - if caller name does not contain [blocked] tag, a call is routed to this step
