How to use MirrorFly VoIP API?

Hi all,

I’m working on a project that needs in-app voice calling, and I’ve been looking into a few VoIP API providers like FreJun, Nextiva, MirrorFly and Ringcentral — has anyone here had experience integrating their VoIP features?

A few questions I’m trying to sort out:

  • Do I need to manage any SIP infrastructure, or is everything handled by their service?

  • How is call signaling and media flow typically handled — do I need to host anything backend-side?

  • Do they offer SDKs for mobile or web, or is everything done through APIs?

Would really appreciate any pointers, sample code, or general integration advice.

Thanks in advance!
