FOP2 WebPhone PRO: Chrome-based WebRTC softphone for Asterisk
FOP2 WebPhone PRO, developed by Asternic Corp, converts Chrome into a WebRTC SIP softphone for Asterisk and FreeSWITCH PBX environments. The app makes and receives calls inside the browser, exposes click-to-call number detection, multi-line SIP handling, transfers and conferencing, and displays real-time extension status through FOP2. It also connects to Asternic ChatBroker for omnichannel messaging, making it suited to receptionists and call-centre agents who want telephony in their web workflow.
What is FOP2 WebPhone PRO used for?
The extension turns Chrome into a WebRTC SIP softphone tightly paired with the Flash Operator Panel 2 switchboard, intended for Asterisk and FreeSWITCH PBX users. It embeds call control, extension monitoring, and a browser-based dialer. Core capabilities include click-to-call, real-time extension status through FOP2, and in‑browser SIP calling, which makes it useful for receptionists and agents who need telephony inside their web workflow.
How does the app behave with multiple lines and active calls?
The PRO version supports multiple simultaneous lines and multi-party conferencing, so agents can handle several active calls and perform SIP transfers from the browser. Because it runs entirely inside Chrome, it removes the need for separate softphone programs and centralizes call handling. Setup requires a licensed FOP2 server and WebRTC-capable PBX configuration, so administrators must provision WSS and SIP credentials before multi-line use is functional.
Does the extension limit data exposure or manage call privacy?
The extension relies on the site-side FOP2 server and an Asterisk-compatible PBX for call routing and signaling, which means call encryption and storage are governed by that infrastructure. Required WebRTC support and WSS imply secure WebSocket transport is part of the deployment. The tool itself handles signaling in-browser and does not replace server-side policies, so privacy controls depend on PBX and FOP2 server configuration rather than the extension alone.
Is it effective for CRM workflows and omnichannel messaging?
The extension opens CRM records and specific web pages when calls connect and supports configurable JavaScript triggers for workflow automation, so agents can fetch customer data automatically. Omnichannel messaging arrives through Asternic ChatBroker integration, enabling WhatsApp, Telegram, Instagram, and SMS handling inside the same interface. Click-to-call detection on pages reduces manual dialing, which helps users who need fast access to contact records during calls.
Practical choice if your team accepts a technical setup trade-off
FOP2 WebPhone PRO suits receptionists and call-centre teams who need telephony embedded in the browser, according to community feedback that praises workflow simplification. The same feedback warns initial setup requires technical knowledge of PBX and WebRTC, so plan for configuration time. A practical tip: run setup and credentials validation in a staging environment before deploying to agents to reduce disruption.
