The Problem

Improve the user experience without replacing the PBX.

PBX migrations are disruptive

Number porting, retraining, and infrastructure changes can turn a phone-interface update into a much larger project.

Desktop phones add maintenance

Physical handsets and separate softphone applications create more endpoints for IT to configure and support.

The existing service still works

A working PBX should not need to be discarded just to give employees a cleaner browser interface.

Compatibility needs validation

SIP, WebRTC, media, firewall, and gateway settings vary, so each PBX deployment should be tested during setup.

How It Works

Connect the extension, then roll out Chrome.

Tabd uses assigned SIP credentials and the configured browser calling transport.

1

Validate compatibility

Confirm the PBX, SIP, WebRTC or Janus gateway, and network settings needed for browser calling.

2

Add SIP credentials

Configure the extension and assign it to the correct workspace user.

3

Install the extension

The user signs in to Tabd and opens the browser softphone in Chrome.

4

Monitor workspace activity

Authorized users can review live call status, history, notes, recordings, and transcriptions.
