[Asterisk-Users] E1 PRI: Unable to set channel to linear mode?
Hi all,
I have some E1 lines plugged into a digium TE410p and all looks happy
but when I try to make an outgoing call I get this error message:
Apr 15 09:28:21 WARNING[9040]: chan_zap.c:3901 zt_read: Unable to set
channel 31 (index 0) to linear mode.
I think "linear" mode is an audio format - like ulaw / alaw? but
I'm
not sure.... Has anyone come across this?
Thanks very much,
Derek
PS I'm in Ireland with EuroISDN
PPS When I do try to make a test call (and get the error message above)
the called party receives the call and, on answering, hears static (it
must be loud too - it was described as a "brain damaging" noise by my
poor test subjects :) ).
My /etc/zaptel.conf has:
span=1,1,0,ccs,hdb3,crc4
span=2,0,0,ccs,hdb3,crc4
span=3,0,0,ccs,hdb3,crc4
span=4,0,0,ccs,hdb3,crc4
bchan=1-15,32-46,63-77,94-108
dchan=16,47,78,109
bchan=17-31,48-62,79-93,110-124
And my /etc/asterisk/zapata.conf has:
[channels]
context=PRI-NTL
switchtype=euroisdn
signalling=pri_cpe
group=1
channel => 1-15,17-31
;group=2
channel=>32-46,48-62
;group=3
channel=>63-77,79-93
;group=4
channel=>94-108,110-124
And my test dial line is:
exten => _011353.,1,Dial,Zap/1-1/${EXTEN}
exten => _011353.,2,Busy
exten => _011353.,102,Busy
