H.248 User's Manual
•
CHANGE_COLLECT_TYPE (Collect Type) - Used only in MFCR2 protocol by
the incoming user to indicate his waiting for the reception of the MF digit of the
requested type. The type can be one of the following:
•
ADDRESS - The user is waiting for the reception of address digits.
•
ANI - The user is waiting for the reception of ANI digits.
•
SOURCE_CATEGORY - The user is waiting for the reception of the source
category.
•
TRANSFER_CAPABILITY - The user is waiting for the reception of the source
transfer capability (line category).

Next State
The Next State column contains the next state the table moves to after executing the
function for that action/event line. When the user selects to stay in the same state, insert
NO_STATE or use the current state.
Note the difference between NO_STATE and the current state name in this field. If the user
selects to stay in the same current state, the unconditional actions (FUNCTION0) at the
beginning of the state are performed. In contrast, NO_STATE skips these functions and
waits for another action to come.
Reserved word "DO" must be written in the next state field if the unconditional actions
(FUNCTION0) at the beginning of the state are used.

Changing the Script File
16.9.1 General
CAS bouncing is filtered globally for each received CAS for each channel. The User
defines the time for the filtering criteria in the protocol table file (see
INIT_DEBOUNCE), and this is above the bouncing in the DSP detection of 30 msec.
ANI/CLI is enabled using ST_INIT ANI parameter with 'YES'. ANI/CLI is supported
using EV_ANI_NUM_DETECTED as the table action for collecting the ANI number in
an incoming call. For outgoing calls, the table's function SEND_DEST_NUM with ANI
parameter l initiates ANI dialing. The ANI number is provided by the User in the
Source phone number parameter of acPSTNPlaceCall().
16.9.2 MFC R2 protocol
Use the SEND_MF script function to generate the outgoing call destination number. In
this case, the first parameter should be ADDRESS (or ANI for source phone number)
and the second parameter -3 to 1 (+1), indicating which digit is sent out of the number
that the string conveyed by the User in the acPSTNPlaceCall().
(+1) implies sending of next digit, 0 implies repeat of last digit, and -1 implies last but
one digit. This parameter actually changes the pointer to the phone number string of
digits. Thus, a one-to-one mapping with the MF backward signals of the R2 protocol
exists.
Using the parameter SEND_FIRST_DIGIT initiates resending the string from the
beginning, (change the pointer back to first digit and then proceed as above). This
parameter is defined in CASSetup.h.
