[chan-capi-users] capi/divas4linux for x86_64

[Daniel Ferrer]

Hi all,
First of all, I'm new to this list, but I've being using Asterisk for
some time ago, and did a little of developement also.

I'm using Divas v3 driver from Melware
(ftp://ftp.melware.net/divas/v3/divas4linux-melware-3.0.10-107.884-1.tar.bz2)
with a "Diva Dialogic Diva 4BRI-8 PCI v2" card on a x86_64 machine
(Mandriva 2007.1 x86_64, kernel 2.6.22.8-1mdvsmp), using chan_capi
1.0.2.
I didn't notice any problems in installation process, or using it,
everything was fine (until now :)). Now I see this post about Divas and
x86_64 compatibility, and I'm starting to suspect...
Now I'm experiencing this weird problem:

After some time with system up and running (couple of weeks or less),
outgoing calls have have 1 way audio. For example, I make a call from a
SIP extension (A) through the BRI line, and I can hear B, but B can't
hear me, no audio at all. Also DTMF's didn't pass so if I call an IVR, I
can't dial an extension.
Incoming calls from BRI are fine, audio is ok in both directions.

The solution appears to be shut down Asterisk and the Divas Driver. I've
tried to unload chan_capi.so module, and load it again without
restarting asterisk, but the same occurs. I didn't try to restart only
asterisk, always I restarted Diva driver also. I'm using latest Asterisk
  1.2.30.2 in this installation.

Any clues? Any suggestion/procedure to debug this? Maybe x86_64
compatibility ? Maybe a bug in chan_capi 1.0.2 (I updated chan_capi to 
1.1.1, and let's see what's happen).

Also I see that is a new Dialogic Diva driver in Dialogic site:
Diva4Linux_installer_8.5-108-106.bin. You've plans to port this to the
corresponding divas4linux-melware version ? I'm offering to help with
this task, if it's needed.


Thanks
bye
daniel

Melware V3 is based on their package without additional 64bit changes, so I
doubt it will work. Maybe a newer version I did not port yet.
Without any customer for 64bit, I don't have any plans on this.
