variable diagnostic_states


vx_participant_diagnostic_state_t * diagnostic_states;

A list of diagnostic states, which tells the application the following information:

The participant is attempting to speak, but the system is not in a state to propogate that speech (for example, the mic is muted).
The participant has unavailable capture or render devices due to certain causes.

variable diagnostic_state_count


int diagnostic_state_count;

The total number of diagnostic states.

variable alias_username


char * alias_username;

The identity of the user if P2P, or NULL if a channel call.

Note: This is different than the participant_uri, which is the actual internal Vivox identity of the original sender.

variable encoded_uri_with_tag


char * encoded_uri_with_tag;

The encoded URI for the user with the tag.

This uniquely identifies users that might appear multiple times in a channel.

variable is_current_user


int is_current_user;

Indicates whether the message is from the current logged in user.

variable has_unavailable_capture_device


int has_unavailable_capture_device;

Indicates if the participant's capture device is unavailable due to reasons other than muting.

Check the event's diagnostic_states for the cause (available for local participants only).

If the participant's render device is still operating, then the participant is "listen only".
If both the capture and render devices are unavailable, then the participant is "unavailable"/"on hold".

variable has_unavailable_render_device


int has_unavailable_render_device;

Indicates if the participant's render device is unavailable.
