signaling models

The Blueworx Voice Response signaling model is based on the CallPath Services Architecture, as defined in the CallPath Services Programmer’s Reference manual (GC31-6824). The main difference is that Blueworx Voice Response does not implement the Routing state associated with automatic call distributors (ACDs).

Figure 1. CallPath signaling model
This signaling model begins and ends at Idle state. From Idle state the route passes in one direction through Pending state to Connected state, and in the other through Routing state to Alerting state and beyond. All states are shown returning directly to Idle state.

There are differences in the responsibilities of the signaling process, depending on whether it is implementing a common channel signaling protocol or one of the exchange data link protocols:

Within Blueworx Voice Response, a common channel signaling process is required to take full responsibility for all the signaling on its supported trunks.
The situation for exchange data link signaling processes is different. With exchange data link protocols, some of the signaling information is carried on the data link, while the remaining signaling is carried on the trunk just as in channel associated signaling. Exchange data link signaling processes are responsible for only some of the signaling for the channels they control.
