Unable to create channel of type 'ZAP' (cause 0 - Unknown)

I keep getting the following message although channels are configured OK.

Unable to create channel of type ‘ZAP’ (cause 0 - Unknown)

[root@pphone log]# ztcfg -vv

Zaptel Configuration

Channel map:

Channel 03: FXS Kewlstart (Default) (Slaves: 03)
Channel 04: FXS Kewlstart (Default) (Slaves: 04)

2 channels configured.

zttool shows:

Current Alarms: No alarms.
│ Sync Source: Internally clocked │
│ IRQ Misses: 0 │
│ Bipolar Viol: 0 │ ces ├─────────────────────┐
│ Tx/Rx Levels: 0/ 0 │ │
│ Total/Conf/Act: 4/ 2/ 1 │

Other than ztcfg and zttool I don’t know what else I can look at to fix the problem. Can some one help?

Also whenI do lsmod I get wctdm (unused) I don’t know if it should be unused?

[root@pphone etc]# lsmod | grep wctdm
wctdm 40192 0 (unused)
zaptel 180800 4 [wctdm]

what does zapata.conf look like

Zapata file looks as below. using zttool everything seems OK.

[channels]
signalling=fxs_ks
language=en
group=1
context=zapout
channels=>3,4

I would like to ask if you have managed to resolve the issue? I have the exact same problem. Everything should work, but I get the same error.

I don’t know if the problem is completely resolved because I am not at home to try it. But, remotely I think I’ve gotten somewhere on this problem.

When I did asterisk -r and ran “zap show channels”, it concerned me that I would only see the psuedo channel listed. The funny thing is, when I used Asterisk@Home 2.2 or something older then the 2.5 I am using, this all worked.

It would appear the genzapconf is broken or something of the like. I removed the zapata.conf and zapata-auto.conf that Asterisk@home generates, the copied over the zapata.conf.template that happened to exist. I changed it to match my config. Now, it works!!!

asterisk2*CLI> zap show channels Chan Extension Context Language MusicOnHold pseudo from-pstn en 1 from-pstn en 2 from-pstn en

I see the three channels, whereas before I did not. I received the same unknown error you received.

For the record, I am using two X100P clone cards and my configs are as follows:

/etc/zaptel.conf:

[code]# Autogenerated by /usr/local/sbin/genzaptelconf – do not hand edit

Zaptel Configuration File

This file is parsed by the Zaptel Configurator, ztcfg

It must be in the module loading order

fxsks=1-2
loadzone = us
defaultzone = us
[/code]

/etc/asterisk/zapata.conf:


[channels]
language=en

; include zap extensions defined in AMP
include zapata_additional.conf

; XTDM20B Port #1,2 plugged into PSTN
;AMPLABEL:Channel %c - Button %n
callerid=asreceived
context=from-pstn
signalling=fxs_ks
faxdetect=incoming
usecallerid=yes
echocancel=yes
echocancelwhenbridged=no
echotraining=800
group=0
channel=1-2

The only thing I really see different from the older config is the use of => on channels is removed, = is used in it’s place, and the channels are now grouped together rather than being specified individually.

(I should also mention, I updated the zaptel driver to the one from cvs. I don’t recall this having a postive affect on the issue)

I don’t know if this will apply to your situation, but you may wish to try it.

Let me know if it also works for you.

Thanks,
Mark

Thanks mark, My problem was similar to your. I didn’t change => to = but instead I had to change channels=> to channel=>. In my zapata.conf I had channels=> and it should have been channel=>
