Yes — Telnyx supports conference calls. You can create them using Telnyx APIs or by connecting Telnyx to your existing phone system.

You have a few options:
Voice API (recommended): Build and control conference calls programmatically
TeXML: Create simple conference rooms using XML instructions
SIP trunking: Use Telnyx with PBX systems like Asterisk or 3CX
Video API: Build audio/video conferencing apps
