[Asterisk-Users] zaphfc hardware & sound trouble

[nni at gmx.net]

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 at 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

Jul 25 22:51:18 WARNING[163851]: PRI: !! Got a UA, but i'm in state 1

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.
