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.
