Some missing telecom related icons
Hi,

**Describe the requested icon**
In the telecom area, the phone icons are great, but some are missing, such as:

- Calls list (could be a mix of phone and list icons you already have)
- Call transfer (could be a mix of phone and arrow-right)
- Paused call (could be a mix of phone and pause)
- Dialer / numpad (nine or ten squares in a grid with 3 columns for example)
- Screen sharing (it's often an arrow to the top in a square)

Also a voice recording icon (voice message sent though chat) would be great.

**Additional context**
I'm working on https://github.com/BelledonneCommunications/linphone-android and we are considering using your library for our new UI.

Thanks in advance!
