[Asterisk-Users] Coexistence of zaphfc and hisax?

[Stefan Helbing]

Hi,
currently I got the following problem:
The system contains a HFC-PCI card, it's running without problems under zaphfc.
Now this system also should send/receive faxes. Receiving faxes works with rxfax (spandsp) but txfax is not comfortable enough and doesnt bring the demanded results. So an older external ISDN modem and mgetty-sendfax is used for sending faxes.

I'd like to send the faxes also via the HFC card but I don't have any common interface for it:
mISDN doesn't support faxes, CAPI is available for active cards only (I believe - if I'm wrong please correct me) and HiSax plus ISDN4LINUX doesn't work:
I tried to load the hisax module parallel to zaphfc but this immediately results in a message
"Primary D-Channel on span 1 down"
in asterisks log. After a rmmod of hisax and rmmod/modprobe of the zaphfc module asterisk works again.

Does anybody have an idea how I'm able to provide a common interface like CAPI or ttyI to my fax software?

Thx
Stefan
