Not all XMPP clients support calling, and some work intermittently depending on which version you're using. In addition, clients like Movim may behave differently depending on your web browser configuration. This aims to be an incomplete list of calling compatibility across popular clients. "DTMF" refers to dual-tone multi-frequency signaling or what is commonly referred to as a dialpad to allow for number input during phone calls.
Movim browser compatibility matrix
The other person's Jabber ID needs to be in your roster and they need to share presence with you in order for Movim to present the audio/video call icons.
