Asterisk VoIP server setup with Android client side using PJSIP library

We are looking for technical solutions for our Asterisk VoIP Server setup with Android as client side that uses pjsip library.

VoIP feature in our application connects one user to another similar to WhatsApp calls. We have done the Asterisk server setup but we seek solutions for following:

1. When a user is calling we are unable to identify the callerId for the second user.

2. When the second user is offline we are unable to connect.

3. Require recorded voice messages that are played when another user is busy/offline etc
