hi list.
after my unsuccessfull experiences with mISDN i tried again to implement
a zaphfc based solution.
problem is: sound on calls via capi is stuttering/broken and therefore
unuseable.
my conf:
- cel 1300, 256mb ram
- avm b1 via capi connected to my outgoing ISDN
- acer surf pci via zaphafc and crosslink cable with termination as
internal bus
- siemens gigaset 3035 as internal phone
- various sip-phones on my pc to test
software versions:
- gentoo with kernel 2.6.9
- bri-stuff.0.1.0-RC4a installed with
cvs -z9 co -D '2004/08/21 21:34:58' asterisk libpri zaptel
all worked fine and this was the first time i could get the gigaset to
talk to asterisk (in contrast to mISDN).
but ... the sound problem:
ive got stuttering noises, voice is almost not understandable in some
cases - but in every case ;-(
symptoms:
- calls form gigaset to asterisk (demo,menu etc) are ok
- calls from gigaset via asterisk to pstn have stuttering
- calls from sip via asterisk to pstn are ok
- calls from pstn to asterisk (demo, menu etc) have stuttering
- calls from pstn via asterisk to gigaset have stuttering
- calls from pstn via asterisk to sip are ok
what me stikes here is that you cant find a definitive suspect here.
zaphfc itself seems to be ok - demo and menu sound are ok and otoh i get
problems when zaphfc is out of the game - like calling asterisk alone
from pstn.
but capi itself works - at least when i use sip to call out.
ive got to stop scratching my head about this before i loose to much
hair ...
i googled around and found no solution. what i tried:
- the hdparm thing
- switching apci/acpi
- changing resitors for termination of the internal bus (100/50 ohms) or
remove termination completely
one thing that makes me curious are interrupts:

there was no activity on the system and zaphfc produces interrupts like
crazy. i found one post describing the same thing - but the thread
concludes without solution ...
someone got ideas ?
or maybe i could try another approach:
has anyone got a similar working configuration (isdn external & internal
via capi and/or zaphfc and/or mISDN) ?
which hardware / software do it run on ?
wbr.tja...
Hi I recommend you abandon the old card with the CAPI drivers and purchase a second HFC card. You can get them for around ?10/EUR15 approx if you shop around on the net. You need to use zaphfc and the native zaptel and libpri drivers. You will need the bristuff from http://www.junghanns.net/asterisk/downloads/bristuff-0.2.0-rc2b.tar.gz which has a script to download and install the whole thing automatically. The HFC card will generate 8000 interrupts per second. it is normal operation. Do make sure you are not sharing these IRQs or you will have problems. I have 3 HFC cards running in an Celeron 400.
