The digit-map action can only be specified for the digits, letters and inter-digit timers in
the MF and DTMF packets, or in other packages that need to define the encoding of
digits and timers.
The requested list is encoded on a single line, with event/action groups separated by
commas. The following is an example of RequestedEvents encoding.
R: hu(N), hf(S,N)
R: hu(N), [0-9#T](D)
z SignalRequests (S)
The SignalRequests parameter provides the name of the signals that have been
requested.
Several signals, such as announcement or ADSI display, can be qualified by
additional parameters:
the name and parameters of the announcement
the string that must be displayed
These parameters are encoded as a set of UTF8 character strings, separated by
commas and enclosed within parenthesis, as in:
S: adsi("123456 Francois Gerard")
S: ann(no-such-number, 1234567)
When several signals are requested, their codes are separated by commas, for
example:
S: asdi(123456 Your friend), rg
z ObservedEvents (O)
The ObservedEvents parameter provides a list of events that have been observed.
The following are examples of observed actions.
O: L/hu
O: 8295555T
O: 8,2,9,5,5,L/hf,5,5,T
O: L/hf, L/hf, L/hu
z ConnectionParameters (P)
Connection parameters are encoded as a string of type and value pairs, where the
type is either a letter identifier of the parameter or an extension type, and the value is
decimal integer. Types are separated from value by an equal sign (=). Parameters are
encoded from each other by a comma.
Table 5-8 shows the connection parameter types.
