Hello,
I’m trying to install my first Digium card (model TE220B). I downloaded the Zaptel source code (zaptel-1.4.4) and compiled it. Some warnings appeared about deprecated code (looks to be deprecated code in the linux kernel -2.6.22-, not in the Zaptel drive itself).:
warning: 'deprecated_irq_flag' is deprecated (declared at include/linux/interrupt.h:66)
Another more important warning was a complain about implicit declaration of pci_module_init:
wcte12xp.c:2015: warning: implicit declaration of function 'pci_module_init'
I searched throught the linux kernel source and found not such declatarion which made me think something was really wrong.
Still the kernel modules (*ko) were generated and properlly installed.
Then I configured /etc/zaptel.conf and /etc/asterisk/zapata.conf. Started Asterisk and … nothing. When “starting” the module the flashing “red light” in the card changed to green, but that’s all. Then conecting to Asterisk:
~> asterisk -r
Connected to Asterisk 1.4.11 currently running on LaPantoja (pid = 20796)
LaPantoja*CLI> zap restart

The most curious is that if I try a second time:

[Aug 24 12:30:48] WARNING[20838]: chan_zap.c:9764 zap_restart: Reload channels from zap config failed!
The error is different and asterisk CPU ussage grows up to 100% until I restart it (I think this is a “marginal” bug in Asterisk, isn’t it?).
Thanks in advance for any help, hint or link!
Regards!

More info about the issue.
I “rolled back” to a kernel 2.6.18 and the compiling warnings dissapeared. Still when I try to make a
LaPantoja*CLI> zap restart

I got sure everyone had permissions to access /dev/zap/1 (2,…) still I get the “Device or resource busy”.
Just for curiosity I tried:
~> cat /dev/zap/1
LaPantoja:/usr/src/zaptel-1.4.4# cat /dev/zap/1
TTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTT
TTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTT

Completly lost at this moment 
Are you starting zaptel before starting Asterisk? Also since you are on Asterisk 1.4 I would suggest staying with Zaptel 1.4. Try the latest release of zaptel (as of now 1.4.5.1)
Hi,
I’ve only used Digium analog cards so I am not at all sure of this, but do you also need ‘libpri’ to work with the TE220?
It’s a T1/E1 card and I believe that’s what libpri supports.
Info from Asterisk download page;
asterisk.org/downloads
Are you sure you have a proper kernel. New Digium hardware needs a very recent kernel. You shoul check the manual on this.
If you have problems with getting a Digium card up and running Digium will help you with this, the support is part of the deal (afaik)
Thanks all for your help.
I continued the testing. Looks like zaptel was actually working but it just breaks when doing a “zap restart”.
I connect to the asterisk console and switched-on pri debug span 1.
Then I can see the call arrives and is detected by the hardware:

Does anyone knows how to interpret the error?
Thanks you!
