We curently have a centos 5 / asterisk 1.4 server that we have some DTMF
problems with. It has a Sangoma A104d card and only port one is used to
connect to the PSTN. Port 2 is conencted via a cross-over cable to a RAS for
modem access and port 3 is connected for data communication via PPP.
Now, I want to freshen this setup to something newer. So I installed a
Scientific Linux 6 server, with asterisk 1.8 and the latest Sangoma drivers
and an A101 card I had laying around.
I did a test this weekend and pluged in our PRI in that test server. I never
got succeded to have a call trough. When I dialed in, the call is “hanged
up” with :
Channel 1/1, span 1 got hanup, cause 6
Spawn extension (ael-default, s, 3) exited non-zero on
Here’s my dahdi/system.conf :
#Sangoma A101 port 1 [slot:0 bus:6 span:1]
my asterisk/chan_dahdi.conf is rather long, but is mostly defaults, with :
channel => 1-23
as the last non-commented lines.
So, for one thing, the card I have in my test server doesn’t have an
hardware echo canceller, but it’s still enabled in my wanpip setting. Could
that be a source of problem ?
Other than that, is there anything obvious I’ve missed ?
