One platform. Four different jobs.
Abbax Voice adapts to how your team actually uses the phone. Pick your scenario.
Dial faster, from wherever you're working.
Start a call from a web page, a CRM record, or any number you highlight on screen — Abbax dials it. Choose which of your numbers shows as caller ID, and record the call to play back later.

- Highlight-to-call — highlight a number anywhere on screen
- Multiple CLI options — pick your outbound caller ID per call
- Cloud call recording — play any call back, from any device
Context on screen the moment you answer.
A screen pop opens the caller's record in your CRM or helpdesk as the call connects, and the caller's name comes from your shared phonebook — so agents start the conversation already knowing who they're talking to.
- Screen pop-ups — open the right record before or after answering
- Visual call parking — one-click park and retrieve, with BLF status
- Call control — attended or blind transfer, conference, hold, mute
- Presence & BLF — see who's free before you transfer
One app for calls, chat, and meetings.
Keep coworkers in sync without juggling tools — team chat, video meetings, and conference calls live in the same app as your phone system.
- Rich business messaging — private & group chat, files, audio messages
- Video conferencing — HD video, audio and screen sharing
- Conferencing — merge callers into one conversation
- Presence & BLF — see who's free before you call
The same app, on every device you use.
Windows, macOS, Linux, iOS and Android — plus your desk phone. Move a live call between them without hanging up, and keep talking when your phone switches from Wi-Fi to cellular.
- Call switch — move a live call between mobile, desktop and desk phone
- Wi-Fi to LTE handover — the call survives the network change
- Push notifications — never miss a call while the app sleeps
- Companion mode — fewer duplicate rings when you're at your desk
