Centralized PBX Extension & Contact Management with Mr. VoIP Tools

Keeping extensions, contacts and directories in sync across your PBX and CRM usually means the same update done two or three times over. Mr. VoIP's extension management API removes that duplication — add, edit and delete PBX extension accounts, push voicemail PINs and configuration links, and have your CRM and telephone directory update automatically alongside the PBX. The API is resource-oriented, using standard HTTP methods and JSON, so it drops into whatever backend you're already running.

Individual accounts can still be tailored where it matters — a unique meeting room name, a personalized inbound number, or a dedicated 3CX web meeting link for a given user. If your team is managing extensions by hand across multiple systems, get in touch and we'll walk you through what centralizing that looks like.
