Softphone and browser dialer

Every member gets a browser dialer inside the Comcent web app. It is a WebRTC softphone, so agents need only a browser and a headset.

What the dialer does

• Dial pad for numbers and member usernames, with DTMF tones during a call.
• Outbound number picker to choose the caller ID (see Outbound caller ID).
• Incoming call panel with Answer, Decline and Ignore, a ringtone and browser notifications. Other calls waiting at the same time are listed under Also Waiting.
• Mute and Hold. You can hold several calls, start a New call, and Resume Call later.
• Blind Transfer and Attended Transfer (see Call transfers).
• Status menu to set your presence: Available, On Break or Logged Out.
• The dialer window can be dragged anywhere on the screen.

Note

Allow microphone and notification access when the browser asks. Without microphone access calls connect with no audio from your side.

How it connects

The dialer registers with Comcent over SIP on a secure WebSocket at wss://<COMCENT_DOMAIN>:5063/sip-ws, using your SIP username and SIP password. Closing the browser or losing the connection unregisters the dialer and sets your status to Logged Out; when it registers again your previous status is restored.

If the dialer cannot register on a self-hosted instance, see Troubleshooting.

Use your own SIP phone

You can also register a desk phone or a softphone app. The SBC accepts registrations on port 5060 (UDP and TCP) with digest authentication.
