Using the subroutines in the Blueworx Voice Response signaling library, you can use signaling protocols not otherwise supported by Blueworx Voice Response, including:
- Exchange data link protocols, which are sometimes used to send call information from the switch to the voice application (for a high-level view, see Figure 1)
- Specialized intelligent network (IN) protocols (for a high-level view, see Figure 2)
For more information about exchange data links and common channel signaling, see Planning the telephony environment. When you write a program using subroutines from the signaling library, that program is known as a signaling process.
