Delphi documentation

Build voice applications, connect telephony and keep your deployment running.

New to Delphi? Start here

Find your starting point — follow the path from access and an application to a flow and its conversations.

What do you want to do?

• Use Delphi

  Build an application, edit its flow, choose recording outputs and review conversations.

• Administer

  Manage team access, shared settings, recording storage and SIP routing.

• Operate

  Prepare a deployment, investigate failed calls and recover service.

• Integrate

  Connect your systems to Delphi and find the relevant interface contract.

Follow a complete procedure

• Change and verify an existing app — to save, test and publish a flow change
• Deploy or update an installation — to configure, activate and verify a release
• Connect a browser application — to open a browser session from your own web application

Solve a specific problem

• A call does not route or ends unexpectedly — to trace routing and termination back to configuration
• A recording or transcript is missing — to check selection, processing, storage and playback
• Choose transcript-only recording — to keep transcripts without storing audio
• Keypad collection times out or ends too early — to check DTMF delivery and the node's timeout settings

Browse the references

• Web UI: screens and actions — to find the screen that holds a control
• Logs and diagnostics — to choose the right evidence source for a problem
• Log levels and object structure — to read individual log and call records

Explore a subject across responsibilities

• SIP and call handling — to connect trunk setup, flow behavior and call diagnosis
• Recordings and storage — to connect recording selection, storage and output

Use the version selector for your deployment. Interface reference snapshots have their own version labels. Open the version archive to read the documentation for an older release.
