[Asterisk-Users] zaphfc hardware & sound trouble

Hi,

I've been learning asterisk for a couple of weeks now - and it worked for me
as faar as standard configurations where concerned (sip/iax
outbound/isdn4linux & capi with AVM Fritz!, Digium X100P FXO).

Now I recently I'evaluating to use asterisk as a replacemnt for our
companies  (15 employees) legacy pbx system and I'm experiencing multiple
problems with the hfc isdn cards:

My evaluation configuration looks like this now:

######################Problem:

a) when i try to make an inbound call to <msn> I get the following message
on the cli prompt

    -- Going to extension s|1 because of immediate=yes
    -- Extension 's' in context 'alex' from '17109904'
does not exist.
Rejecting call on channel 2, span 1

s doesn't exist, that is true, but I would like to receive calls for the msn
38588 an none else, thus the way it worked for capi doesn't seem to work
here

same is true when I dial out - I can't set the outgoing msn, thus my
provider sends out the call as a global call on the bri line (Austrian
specialtry - as bri connections come without msn's and only with one number
configured as a global number which lets all devices on the isdn bus ring) -
as I have multiple msn's I want to dial out/in on a specific one

b) the combination of my configuration with zaphfc and the acer pci isdn
card seems to cause some other trouble

after some time when the zaphfc driver is loaded I get the following
messages in /var/log/syslog

Jul 29 23:46:49 faar kernel: sync lost, pci performance too low!!!.

The system is almost unusable then, but once asterisk ist stopped and the
zaphfc drivers are unloaded everything is fine again. I tried the HFC Card
in different slots (each with unique irq, but now difference).

c) I don't get a line immediately from my grandstream budgetone phone (see
extension.conf) - I miss the first 3-5 seconds of a call (if I call my
mobilephon's voicebox I just get the beep, but I miss my message before) -
strangely that doesn't happen if I use the x-ten softphone from my pc

d) as long as the line works, I have clearly audible clicks/cracks in the
line (zaphfc) that didn't occur using capi and the avm fritz! pci 2.0 - I
don't have any sound problems on iax via voiptel.org or internally using sip


e) when I start asterisk - I allways get a 

Jan  8 22:58:55 WARNING[81926]: File chan_sip.c, Line 464 (retrans_pkt):
Maximum retries exceeded on call
5bc3c4fe45f84f9e514df5247ae8122c@192.168.0.1 for seqno 102 (Request)

warning - while 192.168.0.1 is the asterisk server and interface configured
in sip.conf as listening interface

f) quite often I get the error on the cli respec. /var/log/asterisk/messages

Jul 25 22:46:38 WARNING[163851]: PRI: !! Got reject for frame 4, but we have
nothing -- resetting!

and

and

Jul 26 21:40:45 WARNING[163851]: PRI: !! Got reject for frame 22, but we
have nothing -- resetting!


g) in the beginning I also got the error

Jul 25 21:40:16 WARNING[163851]: PRI: !! Got S-frame while link down

my maybe that was because I had the signalling configured as
"bri_net_ptmp"
instead of "bri_cpe_ptmp" (that has been corrected allready) - I would
just
like to know what the error means

I would greatly appreciate any help - and I'm looking forward to share my
experiences with others - and in case the German speakting readers would
like a German translation please let me know.

[Asterisk-Users] zaphfc hardware & sound trouble

Alex,

I am using zaphfc now.
I also use an Epia V 10000 mainboard (with Nemiah processor).

Try this:
1. asterisk/Makefile MARCH=i586 option
Make sure that when you hit "make", actually --march=i586 will be used
for
an Epia mainboard.
On my system it had choosen i686 (with some little bit older CVS head), and
this had problems in general with sound.

2. Try running CVS Head + bristuff 0.1.0RC2k (not anything other below i)
It fixes problems about audio.
-> German: + Rauschen, Knistern in der Leitung!

You have this error message:
Jul 29 23:46:49 faar kernel: zaphfc: bchan rx fifo not enough bytes
to> receive! (z1=3983, z2=3976)
It will disappear with bristuff 0.1.0RC2k!

3. How do you use bristuff 0.0.2 but also CVS Head 07/25/04 ?
Both don't work together! You have to use CVS Stable if you want to use
0.0.2.

4. Errors
a) Try s/MSN instead of MSN in your extensions.conf dial plan.
d) see 2.
f) That PRI errors seem to be still a major problem with bristuff.
I have them all the time, even not the exact error like you.
g) link frame errors sound to me not strange, not sure about the exact error

Personally I don't see any advantage using a HFC card instead of an AVM with
chan_capi.
Chan_capi seems to me not under the same development pressure like bristuff
and seems
already be more stable.

It makes no difference using zaphfc or chan_capi if you use it for
connecting PSTN (TE).

I only use HFC + bristuff for using NT mode, to connect my existing pbx
system.
; p2mp NT mode
signalling = bri_net_ptmp

Chan_capi with AVM card doesn't support that.

Greetings

Thomas

Why do you define echocancel and context twice?

You should not use immediate=yes for a TE interface since that instructs
asterisk to go to s extension (which is useful for NT interfaces but not
for TE ones).

I have set pridialplan=local and have the msn in exten => msn,... set
including the area code. To only match calls from my cellular phone I use
exten => msn/cellphonenumber,... That works fine for me.

If it still does not work, turn on some debugging and try to catch what is
happening when a call comes.

I had that problem running RedHat Linux 9.0 with kernel 2.4.20-31.9. It
was probably occured by a buggy driver for the IDE controller integrated
on my mainboard, that made the hard disk access interrupts taking too much
time from the pci bus. The problem disappeared after upgrading kernel to
2.4.26.

This problem I still have. This is what I have found out:

First turn with echocancel=no in zapata.conf. The echo cancelling does not
work any good at all if some audio data is missing. That reintroduces echo
while talking to analog phones, of course, but could help finding the
source of your problem.

Then check that your zaptel timing is all right. Try running zttest (in
the zaptel directory) and watch the output. I still have problems with
this one running zaphfc-0.1.0-RC2k on my new Intel Pentium 4 2,4 GHz
system but timing is excellent on my old AMD K6-233 MHz system...
