Programming the In-Band DTMF Protocol8.2.1. Defining an In-Band DTMF Code for an EventTo 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 PBXEach 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 bypassDTMF characters sent by your PBX and not relevant to the unit operation:z Ignore + Length (*9 + two digit number). For example, wild card *906programs the unit to ignore the next six DTMF characters received.z Ignore + Separator (*0 + one digit character). For example, wild card *05programs the unit to ignore all DTMF characters until it receives a 5. Wildcard *0*4 programs the unit to ignore all DTMF characters until it receivesa #. NOTEIn the above examples 5 and # are also ignored.Table 8-1: Entering an In-Band DTMF Code Using a TelephoneDTMF Character Number to DialDigits 0-9 0-9* **# *4A *5B *6C *7D *8Ignore + Length *9 + XXwhere XX is the number of DTMF characters to ignoreIgnore + Separator *0 + Xwhere X is the DTMF character (0-9, *, #, A-D) used asa separatorSource *1, indicates the caller’s number (not currentlyavailable)Target *2, indicates called extension numberDial *2 for each digit in the extension.
