Hello,
I have a problem with Asterisk 1.4 and a Sangoma T1 card (A101). Basically I
can't make the D channel come up no matter what I tried.
I installed the Zaptel driver, the Libpri and the wanpipe driver following
the instructions on Sangoma's web site:
http://wiki.sangoma.com/wanpipe-linux-asterisk-install
The Sangoma card is connected to an Adtran Atlas 550 phone switch which is
also in our office, so I can configure it anyway I want. Both the switch and
the card are set to DMS100. I let the wanpipe setup create the configuration
files, including the zaptel.conf and zapata.conf.
One other thing I noiced, is that the zaptel.conf file created by the
Sangoma setup was showing
span=1,0,0,esf,b8zs
while according to the ztcfg.conf explanation from the sample file, if the
clock is coming from the remote end (in my case the Adtran switch), it
should be:
span=1,1,0,esf,b8zs
So I tried changing that as well, but it didn't make a difference.
The light on the Sangoma card is green, which I assume it means that it can
see the clock from my switch.
If I run "*ztcfg -v*" it reports
Zaptel Version: 1.4.3
Echo Canceller: MG2
Configuration
======================
SPAN 1: ESF/B8ZS Build-out: 0 db (CSU)/0-133 feet (DSX-1)
24 channels configured.
Also "*wanrouter status*" reports
Devices currently active:
wanpipe1
Wanpipe Config:
Device name | Protocol Map | Adapter | IRQ | Slot/IO | If's | CLK | Baud
rate |
wanpipe1 | N/A | A101/2 | 22 | 0 | 1 | EXT |
0 |
Wanrouter Status:
Device name | Protocol | Station | Status |
wanpipe1 | AFT HDLC | N/A | Connected |
One interesting thing I noticed: I have another server running
Asterisk 1.2and a TE110P clone card. On that system I can run "
*zap show channels*" in the asterisk CLI and I get a list of the channels.
On the Asterisk 1.4 box, it tells me the command is not valid. Am I missing
a module or the command was removed ?
Thanks,
Liviu
