Add features for video calling and blocking a contact on linphone

Components

Linphone is an open source android app which is used for communication purposes through messaging and audio/video calling.

Proposal

In the image below you can see the option available for audio call at top of the screen but there is no option for any video calling.

Also when long pressing on a chat you will only get the delete option shown in the image below.

I'm proposing that there should be an option for video call and also an option to block a person on linphone.
In the next section I've provided examples of how these features can be implemented in linphone app.

Mockups / Examples

I've shown how the video option should look like. I've placed it alongside the audio call option. It will be easier to access here.

And I've presented the block option, when you long press on a chat, with the delete option available.

Benefits

The benefits of these features are:

• Video calling will make communication between two parties better as it will not just provide the audio but also the visuals as well. People far off from home can call their families and get to see them live when you have video calling available.
• Having the block option will help you to separate yourself from some unwanted users who you don't want to text or call and those who are annoying you. You can block them from texting or calling you. It's one of the most important features in any messaging app and I think it should be added to linphone too.
