Supported PBX vendors
Six adapters on day one. Avaya, Mitel, RingCentral, and Genesys next.
The adapter pattern is the heart of VoxRidge. Each vendor lives behind one Go interface — implement it once, and the rest of the platform (policy, events, CDR, IVR) just works.
Asterisk
AMI · ARIThe most widely deployed open-source PBX. AMI for control, ARI for media operations and external audio. Integration tested against Asterisk 18, 20, and 22.
FreeSWITCH
ESLHigh-performance softswitch. Event Socket Library for command and event streams; mod_audio_fork for AI assist audio capture.
Cisco CUCM
AXL · JTAPIEnterprise PBX leader. AXL/SOAP for configuration; JTAPI Java sidecar for call control and events. Supports CUCM 12.5+ and Webex Calling.
3CX
XAPI · WebSocketSMB-favored PBX with first-class REST + WebSocket APIs. Quick to wire, well-documented, lots of customers per dollar.
PortSIP
RESTModern REST-first PBX. Cleanest adapter in the catalog — native JSON events, native call control, no shims.
Twilio
REST · TwiML · Media StreamsCloud-only telephony. VoxRidge wraps Programmable Voice + TaskRouter so Twilio looks identical to an on-prem PBX from the application side.
