[hylafax-users] USB Fax routing on SUBADDR or Device

["Giuseppe Dia" <giuseppe.dia@xxxxxxxxxx>]

Hi all,
I?m experimenting with an Hylafax server and USB modems (two A01-PU3 -
WebRunner USB,  see specs below Class 1, V.21 Channel 2 Group 3 fax mode
behind a  Coral PBX)
My server version is HylaFAX   Version 6.0.4 on Ubuntu 10.10 Linux
xxxxxx-hylafax1 2.6.35-22-generic-pae.
While I can confirm that receiving and sending  works as expected (even with
multiple modems attached),  I have some problems with routing.  Routing by
device works flawlessly, but I?m not fully convinced on how Linux enumerates
the modems: what if after some reboot the modem order changes (ttyACM0
becomes ttyACM1)?
My PBX can add a few DTMF digit (not T.30 protocol, as far as I know. The
PBX is a Tadiran Coral and I don?t have so much info on it), but those are
not seen in $SUBADDR.
A typical log would read:
Nov 29 19:05:32 xxxxxx-hylafax1 FaxGetty[22297]: MODEM input buffering
disabled
Nov 29 19:10:22 xxxxxx-hylafax1 FaxGetty[22298]: ANSWER: FAX CONNECTION
DEVICE '/dev/ttyACM1'
Nov 29 19:10:43 xxxxxx-hylafax1 FaxGetty[22298]: RECV FAX (000000031): from
<UNSPECIFIED>, page 1 in 0:00:18, INF, 200 x 100 dpi, 2-D MMR, 14400 bit/s
Nov 29 19:10:43 xxxxxx-hylafax1 FaxGetty[22298]: RECV FAX (000000031):
recvq/fax000000030.tif from <UNSPECIFIED>, route to <unspecified>, 1 pages
in 0:00:21
Nov 29 19:10:43 xxxxxx-hylafax1 FaxGetty[22298]: RECV FAX: bin/faxrcvd
"recvq/fax000000030.tif" "ttyACM1" "000000031" ""
Stopping faxgetty and querying the modem with minicom (ATZ, ATS0=0,
AT+VCID=1, AT+FCLASS=8) does not do anything relevant. 
I can see the line ringing (R?R?) but no caller id or DTMF shows after or
before the ATH1.  I suspect those modems does not support ?Voice? but I
cannot say this reading the specs.
Have you got any idea on how to solve this, or a new idea for a reliable
form of routing basing on some info that I can send to hylafax? To date, the
best solution I have is trying to lock every USB device to an ACMxx device
to make sure it doesn?t change during reboot.
Below your will find the modem characteristic, as the manufacturer site is
in Italian only and it may be difficult to find them.
Thanks and regards,

Giuseppe Dia
