Extension Management

Manage Extensions and Contacts from One Place

With Mr. VoIP's HTTP API we make it super easy for you to manage your PBX extensions from one central dashboard. You no longer have to do multiple manual updates — your CRM, telephone directory and PBX are automatically updated whenever a change is made.

This powerful feature lets you access our services using resource-based URLs, status codes, HTTP methods (POST, DELETE, etc.) and JSON for requests and responses — making it easy to use HTTP clients in your backend for a powerful API interaction.

With our 3CX HTTP API you can add, edit and delete PBX extension accounts, send manual links, configuration files and voicemail PINs, and use the softphone to modify auto-generated credentials and keep customer records up to date.

Customize each user account to meet the unique needs of your PBX extensions. When organizing a web conference, create a unique meeting room name and give participants a personalized inbound call number or 3CX web meeting link — simple, effective and less time-consuming.
