Switch to Telnyx in minutes using your existing XML code.

TeXML Translator covers core commands — conference, dial, gather, hangup, pause, play, record, redirect, reject and say, with more coming soon.

  • If you have an XML application, configure your Telnyx portal connection to point at your XML endpoint. When a call comes in, we’ll do the rest.
  • Or, build a new XML application using simple TeXML commands—called verbs—which you wrap in an XML file.
  • You'll realize significant cost savings and call quality improvements instantly.
