[hylafax-users] R: Implentation of DTMF DID with Hylafax 4.2.3

[<taverni@xxxxxxxxx>]

I have tried to use this settings but do not work.

My modem,DIGICOM Tiziano Voice, do not accept command AT+Class=8, but accept
AT#CLS=8.

I have tried this with Minicom and the result is:

I do not understand in order which Hylafax reason goes in TIMEOUT without
recognize DTMF codes.

Help me.

The hylafax-config manpage has a suggested application description in it.

The special CallID value of "SHIELDED_DTMF" is used in conjunction with 
ModemRingResponse and CallIDAnswerLength. After executing 
ModemRingResponse, HylaFAX will expect DTMF data (usually DLE-shielded) 
for CallIDn until CallIDAnswerLength is reached. Note that if the modem 
is in voice mode to hear these DTMF digits, then it must be returned to 
fax mode in the ModemAnswerCmd. In order to prevent this feature from 
losing incoming fax calls, if fax sender CNG is detected while waiting 
for DTMF or if ten seconds elapse without sufficient DTMF then the 
remaining expected digits will be populated by whitespace, triggering 
fax answering.

For example, the following settings will cause HylaFAX to enter voice 
mode and go off-hook when a RING is detected. It will then expect four 
DTMF digits (presumably for routing), and then it will pause for 100 ms 
before returning to fax mode and answering the call.

  ModemRingResponse:     AT+FCLASS=8;H1
  CallIDPattern:         SHIELDED_DTMF
  CallIDAnswerLength:    4
  ModemAnswerCmd:        <delay:100>AT+FCLASS=1;A

In HylaFAX 4.2.3.1 available at http://hylafax.sourceforge.net/ there 
were various improvements made to the feature that should help those 
people who want it to automatically answer if the fax call is patched 
through before all of the expected number of digits are received and for 
those who want to play voice messages in conjuction with it.  (These 
changes will begin to be be integrated with the HylaFAX versions at 
hylafax.org as soon as they have enough exposure.)

Hope this helps,

Lee.
