Using the softphone

Making and receiving calls from the Suzko desktop / mobile app.

The softphone lives in:

Sign in to the app with your Suzko account; the softphone is enabled automatically if you have a VoIP plan + at least one number.

Making a call

  • Type a number in the dial pad → Call
  • Or pick a contact from your contacts list
  • Or click any phone number anywhere in the app to dial it

Outbound caller ID is the number you've set as default. Change per- call with the dropdown next to the call button.

Receiving a call

When an inbound call hits a number routed to your softphone, the app rings. Accept, decline, or send to voicemail.

If you have multiple devices signed in (desktop + mobile), the call rings on both — first to pick up wins.

During a call

Standard buttons: mute, hold, transfer, keypad (for DTMF tones), record (if not auto-recorded by the call flow).

SMS

In the Messages tab. Pick a number to send from, type the recipient + message. MMS supported on US/CA numbers — drag in images or attachments.

Contacts

Contacts tab. Add/edit, mark as lead, set tags. Used by:

  • Caller ID display (shows contact name on incoming)
  • Lead pipeline filtering
  • Call/message history grouping

Headset / audio device

The softphone uses your system's default mic + speaker. To override: Settings → Audio in the desktop app. We recommend a wired headset — Bluetooth audio adds 100–200ms of latency.

Going offline

Quit the app, or Settings → Stop accepting calls. Calls fall through to the next node in the call flow (usually voicemail).

Call quality issues

  • One-way audio — usually a firewall blocking inbound UDP. Check your network setup.
  • Choppy audio — bandwidth or latency. We need ~100kbps and <150ms RTT for clean audio. Test at speedtest.net.
  • No ring — the softphone might be offline (settings, or no internet). The dashboard's "Status" indicator at the top of the app shows current connection.
