The RCS is contact oriented which means that you do not have to add other users, instead the application should recognize them in your existing contacts. Since the users register with phone numbers it is then possible to find and mark appropriately those numbers in your phone address book.

When the application starts for the first time it sends all the phone numbers to the EMC API. The EMC checks them against registered numbers and responds with the list of RCS supporting numbers.

With every next start the application checks if its current version of the EAB matches the version on the server. If not it synchronizes the local address book with the server.

Branches

Branches shown on the main screen of the application shows structure of your company and would help users to quickly find the contact they are looking for.

All branches, along with contacts inside each branch, can be edited by the administrator using the VUC Administrator panel.

All contacts are added to Default automatically if the administrator does not creature custom-made branches.

Contacts list

The avatars shown on the list are other users profile pictures and are downloaded from the RCS platform. If a user does not have a profile picture the local picture from phone address book will be shown.

Below the list, in the bottom bar are filters:

All contacts
Company contacts only
Favorites

The purpose of the RCS icon is to provide shortcuts to RCS main features. When you click on it three icons will appear representing video call, audio call and chat.

When you click anywhere else on a contact’s row the Contact details view will appear.

Contact details view

This view is an enhanced version of the native contact page.

The view contain avatar, status, Company ID and phone number.

Below Company ID are three buttons:

Make free call button
Send free SMS button
Make free video call button

Below phone numbers are two buttons:

Make call button
Send SMS button

Non RCS contact

The view will contain data stored locally on the phone which include local avatar and phone numbers.

Below phone numbers are two buttons:

Make call button
Send SMS button

Both calls and SMS sent from this view will go through the service and then will be terminated on the destination PSTN network (RCS Out).

RCS contact

The upper part of the view shows the profile picture of the user associated with the contact item (phone number or Company ID). If a user has not uploaded his picture the application will show the native avatar from the local phone book.

Next to the avatar the status text is shown.

The lower part of the screen presents the item (e.g. phone number) and the buttons which initiate one of the RCS free communication types:

Voice call
Video call
Chat

If for some reason you prefer to use paid service and call or SMS the user’s phone number through PSTN network (RCS Out) there are two buttons for paid actions (same as for non RCS contact described above).

Favorites

To mark a contact as favorite you need to click on the favorite icon - a star placed on the bottom bar in the Contact details view. If you want to remove the contact from favorite click on the icon again.

The list of the favorite’s contacts can be filtered in the Contacts view.
