[hylafax-users] race condition

["Moritz Winterberg" <winterberg@xxxxxxxxxx>]

Hi,

I'm using hylafax+ (5.1.4) in conjunction with asterisk to send and receive a couple of thousand facsimiles per day.
Now in very rare cases I get kind of a race condition which actually will link an incoming fax to the wrong recipient.

Here is the hylafax log snippet showing two couples of sender/recipient in one call:

To be more specific, my setup consist of an EICON DIVA SERVER PRI card connected to another PRI card on another machine running asterisk.
Now as I would not know a way to submit two different sets of callerid info through ISDN the Problem must be searched on the Eicon/hylafax layer.

I suspect the EICON drivers to not correctly reseting the modem in some special cases before answering another call. But this is only a guess.

If you have another idea I'd be glad to hear about it. Anyway I think there should be some kind of work around. Is there any hylafax config option which
blocks a modem for a while or resets it after its been used ? Or could an alteration of RingsBefore answer lower the danger of this problem ?

Any idea is appreciated..

find my current device config further down ..

Thanks
Moritz
