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 span=3,0,0,esf,b8zs bchan=49-71 dchan=72 span=4,0,0,esf,b8zs bchan=73-95 dchan=96 and here's my chan_dahdi.conf: [channels] switchtype=national pridialplan=unknown prilocaldialplan=unknown internationalprefix = 001 nationalprefix = unknownprefix = signalling=pri_cpe usecallerid=yes usecallingpres=yes echocancel=no echocancelwhenbridged=no group=1 callgroup=1 pickupgroup=1 faxdetect=incoming context=defaultspan1 channel => 1-23 -- Edwin Lam <edwin....@officegeneral.com> Systems Engineer, OfficeWyze, Inc.
