Webfree

Open Cold Dialer is a free, open-source, browser-based cold-calling application with SIP softphone support, lead management, campaign tracking, call scripts and call history. It works with any SIP provider, such as SignalWire, Twilio or Telnyx, rather than locking users into one telephony vendor, and is self-hostable via Docker.
