By default, for an incoming call, the codec rings and you can see the Incoming Call window with the caller name or IP address, SIP or H.323 domain, and the options to accept the call. The caller name is displayed only if the contact is saved in the address book.

You can join the call only with audio or establish an audio and video call. You can also mute your audio before joining. If the Auto Answer feature is enabled, all incoming calls are automatically answered and you do not need to accept them.
