Supported Call Control Messages
The Simulator supports the ISDN-BRI Call Control messages listed below. For
specification documents that describe the function of each message, see the end of
this section.
Message codings unique to a particular switch vendor or protocol are followed by
the applicable switch type identifier. Not all recognized messages are performed by
the Simulator, and are indicated with (*). For example, while the Simulator will
recognize the AT&T CONFerence message, it will return a CONFerence REJect
message in reply, using the appropriate Information Element Cause code to indicate
the service is not available.
