asterisk users - May 2011 - Trying out a new version with sangoma card

Hi !

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 
'DAHDI/i1/NPANXXXXXX-2'
Hungup 'DAHDI/i1/NPANXXXXXX-2'

Here's my dahdi/system.conf :

loadzone=us
defaultzone=us

#Sangoma A101 port 1 [slot:0 bus:6 span:1] <wanpipe1>
span=1,1,0,esf,b8zs
bchan=1-23
echocanceller=mg2,1-23
hardhdlc=24

my asterisk/chan_dahdi.conf is rather long, but is mostly defaults, with :

switchtype=national
pridialplan=unknown
signalling=pri_cpe
group=1
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 ?

Make sure the firmware on the card is latest. I had a problem, not like your,
and flashing the card to the latest firmware resolved it.

Show us the output of a failed call with pri debug enabled on that span.

It will be difficult, since the PRI is in use on our "old" asterisk
box.
I will have to get to the colo at night, to avoid disrupting calls 
during the day.

Is there any other thing that I should collect ?
