In short

You connect a phone line to Risti from Settings › Apps › Marketplace › Calls & phone. Connect Sipuni or OnlinePBX with its API details, or a SIP line from your operator or office PBX. It takes about 10 minutes, and calls then ring in the browser, where your team answers or lets MaryAI answer.

Before you start

  • Sipuni: the Account number and Integration secret from Sipuni › Settings › Integrations › API.
  • OnlinePBX: your Domain (company.onpbx.ru) and an API key from Settings › API.
  • A SIP line: the number, server, login and password from your operator or office PBX.
  • The Owner or Admin role in Risti, and a browser allowed to use the microphone.
  1. Turn on calls

    Turn on Take calls in Risti: tick the disclosure and press Turn on calls. One switch covers every app.

  2. Open Calls & phone

    Go to Settings › Apps › Marketplace, open the Calls & phone category, pick Sipuni, OnlinePBX or a phone line and press Connect.

  3. Connect Sipuni or OnlinePBX

    For Sipuni, enter the Account number and Integration secret, then press Connect Sipuni. For OnlinePBX, enter the Domain and API key, then press Connect OnlinePBX.

  4. Sync calls and recordings

    On the account page, use Sync calls and recordings: copy the Webhook URL into Sipuni’s call events or OnlinePBX’s webhooks. Sync now fetches them on demand.

  5. Answer calls in Risti

    Use Answer calls in Risti to make Risti one more extension: enter the Extension login and Password, press Connect the extension, then put that extension in your call scheme where Risti should ring.

    Tip. You can use one or both: sync calls and recordings, and answer calls in Risti.

  6. Or connect a SIP line

    Enter the Number, Name, Server (host:port), Transport (UDP or TCP), Login and Password, then press Connect the line. The status “Registered: calls ring here” means it works.

  7. Answer in the browser

    Allow the microphone. Calls ring with Answer and Decline. The conversation’s person rings alone first, then everyone who can see it.

What happens next

  • Synced Sipuni and OnlinePBX calls land with the chosen team with their recording; with Transcripts and AI summaries on, they also get a transcript and summary. Recordings arrive a minute or two after the call.
  • A SIP line takes incoming calls only, and MaryAI can answer them.
  • Risti doesn’t record the SIP line calls your team answers; calls MaryAI answers are always recorded and transcribed. Synced Sipuni and OnlinePBX calls bring their own recordings; for other calls, see call recording.
  • Team leads can listen, whisper or join the call from the agent’s card in Ristiville. The caller never hears a listener.

If it doesn’t work

Which phone systems work with Risti?

Sipuni and OnlinePBX connect directly, and any SIP line from your operator or office PBX connects as a phone line. Risti does not provide phone numbers.

Can I make outgoing calls over a phone line?

No. A SIP line connected to Risti takes incoming calls only.

Are calls recorded?

Calls your team answers on a SIP line are not recorded by Risti; calls MaryAI answers always are. Calls synced from Sipuni or OnlinePBX bring their own recordings. For other calls, an owner or admin turns on Record calls in Settings › Apps › Call recording, and callers hear a spoken notice first. Safari can’t record.

Do I need a desk phone?

No. Calls ring in the browser. Allow the microphone, then press Answer or Decline.
