is there static on the line??
no. there were customer complains about sound cutting in and out.
however i wasn't noticing and bad sound quality when i was testing it.
is there timing slips and crc4 errors?
no. the only messages i have are the HDLC abort warning.
are they increasing throughout the day?
they happen randomly, and quite frequently.
are you getting timing slips during the day when users are using the phones and
not off-peak hours?
no timing slips related messages in either Asterisk's logs
or syslog.
are you getting hdlc abort erros when you hear a static noises??
that i don't know. however there was once it happened
while i was in the middle of a call but i couldn't hear
any sound drop off or any static.
is the card sharing irq?
no. this the only card that uses IRQ 30

hi folks.
recently some of our customers complained about bad voice
quality on the phone system. i looked at the logs and found
a lot of these:
[2012-11-03 08:26:38] NOTICE[11305] chan_dahdi.c: PRI got event: HDLC Abort
(6) on D-channel of span 1
[2012-11-03 08:26:45] NOTICE[11305] chan_dahdi.c: PRI got event: HDLC Abort
(6) on D-channel of span 1
[2012-11-03 08:26:54] NOTICE[11305] chan_dahdi.c: PRI got event: HDLC Abort
(6) on D-channel of span 1
i upgraded Asterisk/dahdi/libpri. tried turn on/off echo canceller etc.
nothing seems to help. call the phone company to check out the line
(which they said it's working fine)
any idea? do i have a hardware issue here? i've check syslog
there was no dahdi errors.
here's my system.conf:
span=1,1,0,esf,b8zs
bchan=1-23
dchan=24
span=2,0,0,esf,b8zs
bchan=25-47
dchan=48

bchan=49-71
dchan=72
