Description of features

1v1 messages

Client is able to send, receive and display text messages to / from friends.

If client doesn't implement Message splitting, message size is limited to 1372 bytes.

Audio

Client is able to capture, send, receive and play audio to / from friends, using toxav.

Audio filtering

Client is able to filter out noise from captured audio using libfilteraudio¹⁾.

User should be able to tun on / off audio filtering.

Audio notifications

Client should be able to play sound upon receiving message / call / other. There should be an option to turn those notifications off, or tune them according to user needs.

Avatars

Support for avatars according to STS²⁾.

Changing nospam

Support for changing nospam via UI. NoSpam is a small part of a Tox ID that can be changed with an explicit action from the user to prevent friend request spam, if the client supports it.

Chat logs

Client should have support for saving, loading, displaying and removing chat logs (history) of conversations.

Contact aliases

Client should allow user to set, display and remove alias for any friend.

Contact blocking

Client should allow user to block / unblock contacts.

Blocked friends would be unable to contact user, and user would appear to them as offline even if user is online.

Proxy support

Proxy support can be HTTP or SOCKS5 (or both). For an example of a proxy configuration, see Tox over Tor.

Message splitting

If client supports message splitting, a user sending a message larger than the maximum size means the message will be split into several separate messages and sent as normal.

Faux offline messaging

Faux offline messaging is a partial support for offline messaging. If client supports it, it is possible to message offline contacts, in which case the message will be stored by the client and sent immediately once both contacts are online.

File resuming

File resuming is the ability of a client to resume broken file transfers. Partial support is support for pause and resuming file transfers.
