This "<play:2>" look suspisions.. You really have a file called "2" in
/var/spool/hylafax?

From the HylaFAX-config man page:
    http://www.hylafax.org/man/4.4.3/hylafax-config.4f.php

	The ‘‘<play:filename>’’ escape can be used to play a raw audio file with
	a voice modem. This feature can be used, for example, to play a brief
	audio message after picking up the line but before answering. A
	configuration example may be:

	  ModemRingResponse:  "AT+FCLASS=8;H1\nAT+VSM=131\nAT+VLS=1\nAT+VTX\n<waitfor:CONNECT><play:/sounds/enter-extension.raw><waitfor:OK>AT+VTS=[933,,150]"
	  ModemAnswerCmd:     "<delay:100>AT+FCLASS=1;A"
	  CallIDPattern:      SHIELDED_DTMF
	  CallIDAnswerLength: 4

Your DTMF detection should happen *before* the call is "answered"
(ModemAnsewrCmd), and will be logged in in syslog, not the session log
(which starts when the call is "answred" (ModemAnswerCmd).

Remember in this setup, your actually instructing the modem to answer
the call with your ModemRingResponse *before* HylaFAX enters it's normal
"answering" phase.
