The inputs can be assigned at runtime or stored in a database using a suitable provisioning system. The following diagram shows the connection between WebRTC and the IMS Core Server:
For demonstration purposes, we can use an Application Server that can host SIP servlets and integrate them with IMS core.
Mobicents SIP Servlet and Java APIs for Integrated Networks-Service Logic Execution Environment (JAIN-SLEE) are open platforms to deploy new call controller logic and other converged applications. The steps to install Mobicents TAS are as follows:
Download the SIP Application Server logic package from https://code.google.com/p/sipservlets/wiki/Downloads.
Unzip the contents. Make sure that the Java environment variables are in place.
