chan_zap doesn't find my TDM card

Asterisk Asterisk Support
1

Hi,
I just install a brand new TDMcard with one FXO and one FXS in my PC.
zaptel 1.2.5 seems to find it correctly (below log of modules in debug).

But not Asterisk (see log below).

My pc is a P4 1.8 doing firewall, mythtv and perhaps asterisk, running ubuntu breezy with an kernel 2.6.16.11 from kernel.org.

Please help.

Thanks.

Ztcfg too.

I think you have the wrong signaling specified in your zapata.conf file.

Channel 01: FXS Kewlstart (Default) (Slaves: 01)
Channel 03: FXO Kewlstart (Default) (Slaves: 03)

[i]signalling=fxs_ls
callerid=asreceived
group=2
context=incoming
channel => 1

signalling=fxo_ls
group=1
context=default
channel => 3[/i]

For FXO channels you have to use FXS signalling, and for FXS channels you have to use FXO signalling. It seems wierd at first, but that’s how it works. Try…

signalling=fxo_ls ; not sure this may need to be fxo_ks
callerid=asreceived
group=2
context=incoming
channel => 1

signalling=fxs_ls ; not sure this may need to be fxs_ks
group=1
context=default
channel => 3

I’m not sure if this matters, but you configured your devices in zapatel.conf to be kwelstart, then you use loopstart in zapata.conf. They may both need to be the same. I’m not 100% though, I have only done this a few times.

Good Luck,
Dan

Thanks,
I adjusted that (I was trying different zaptel et zapata files from samples around the web).

Still the same error.

I try to trace in the zaptel and wtcdm modules what’s going on.

I thought of this after my inital post. Are you /dev/zap/* devices created? Also make sure they have the correct permissions for the user you are running asterisk as.

my dev zap are correct :
root@titus:~/zaptel-1.2.5 # ls -al /dev/zap/*
crw-rw---- 1 root root 196, 1 May 5 10:01 /dev/zap/1

I try to follow what happend in the zaptel/wctdm driver

If you bought the card NEW (not gray market), I believe that you are entitle to some free support from Digium. You should give that a shot.

Good idea,
the card is brand new from a digium reseller here.
Will try to write them a email from home tonight with serial number …

thanks for your help, I found my problem after drilling module code with printk debug !

I have two card on my tdm400, slot 2 and 4. I was thinking that they start from 0 to 3.
ztcfg never report anything about setting non existing module :frowning:

I adjust my zaptel number and my zapata number too, now asterisk see both modules.

Next step trying to understand asterisk. It seems very impressing but far far from being ‘user friendly’ to configure.

Thanks.
