2.1. Global Call Over IP Architecture with an Embedded Stack

Global Call supports a system configuration where the IP signaling stack is running as embedded software on an IP resource board (a DM3 board) and that board's network interface card (NIC) is used to access the IP network. The IP Media stream is also processed on the same IP resource board as the signaling stack.

Note: Global Call cannot be used for IP call control in a system configuration that uses a host-based stack, that is, the IP signaling stack is running on the host. However, the IP Media Library (for media resource management) can be used in such a configuration.

Figure 4 shows the Global Call over IP architecture in this context.
