Programming the In-Band DTMF Protocol
8.2.1. Defining
an
In-Band
DTMF Code for an Event
To define an In-Band DTMF code for an event, dial:
*200 + XX + YY...YY + #
XX = Event number (00-39)
YY...YY = In-Band DTMF code sent by the PBX
Each DTMF code can contain up to twenty characters, including 0-9, A-D, *, #,
source and target. You can also include the following two wild cards to bypass
DTMF characters sent by your PBX and not relevant to the unit operation:
Length (*9 + two digit number). For example, wild card *906
programs the unit to ignore the next six DTMF characters received.
Separator (*0 + one digit character). For example, wild card *05
programs the unit to ignore all DTMF characters until it receives a 5. Wild
card *0*4 programs the unit to ignore all DTMF characters until it receives
a #.
NOTE
In the above examples 5 and # are also ignored.

*9 + XX
where XX is the number of DTMF characters to ignore
Separator
*0 + X
where X is the DTMF character (0-9, *, #, A-D) used as
a separator
Source
*1, indicates the caller’s number (not currently
available)
