[hylafax-users] DTMF detection

[Matt Baldwin <MattB@xxxxxxxxx>]

Am trying to set up my multitech MT5600ZDXV to receive DTMF digits that my
PBX spits out to the line upon answering.  In my config I have:
ModemRingResponse: 	"AT#CLS=8\nAT#VLS=4\nATA"  #go into voice mode on
ring, enable line and spkr and answer
ModemAnswerCmd: 	"AT+FCLASS=1;ATA"  #switch to class1 then answer
RingsBeforeAnswer: 	0  #disable auto-answer
CIDNumber: 		"."  #format of the DTMF digits ("CID")
QualifyCID:		etc/cid  #create this
CIDNumberAnswerLength:	5  # 5 DTMF digits - then answer
*In theory* this should allow the modem to detect the DTMF tones that the
PBX spits out, then switch to class 1 and answer the line.  
If I step thru it in Minicom I am picking up the digits.  I launch minicom
and type
AT#CLS=8 
(returns OK) then 
AT#VLS=4
and get a ^Ph as a response.  Then I ring in on the line, when I see "ring"
in the minicom window I type ATA, and get
VCON
.1.2.3.4  (Digits from PBX)
then type AT+FCLASS=1 to switch to class1, and type ATA and it will answer
and I get a CONNECT message.
BUT when I let Hylafax handle things, I get the following:

FaxGetty[21166]: --> [4:RING]
FaxGetty[21166]: <-- [9:AT#CLS=8\r]
FaxGetty[21166]: --> [2:OK]
FaxGetty[21166]: <-- [9:AT#VLS=4\r]
FaxGetty[21166]: --> [2:^Ph]
FaxGetty[21166]: --> [2:OK]
FaxGetty[21166]: <-- [4:ATA\r]
FaxGetty[21166]: --> [4:VCON]
FaxGetty[21166]: MODEM TIMEOUT: reading line from modem
It just seems to sit at the VCON (Voice Connection) response code until the
30 second timeout period, never picks up the digits or does anything
else....  I've made sure I matched all the initialization that hylafax does
so that it is exactly the same condition as minicom is when I do it
"manually".  Anyone have any ideas?
Thanks!!
