 OK you don't like asterisk - sorry. Obviously some other software works

 For at least some of us, asterisk works extremely well in demanding 
 environments. But not perfectly. So the collegial help from the mailing 
 list and bug spotting is quite important.
 
 Sorry you don't want to participate.

FWIW, I also consider Asterisk's behaviour here buggy.

[asterisk-users] Unable to create channel of type 'DAHDI' (cause 0 - Unknown)

2010-01-28 Thread Walter Arguello
Hi,

I have a tdm22b (2 fxs / 2 fxo)

When Asterisk is just started, outbound calls routing to fxo port, do not 
working with error:

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

Inbound calls to fxo port work fine.

After first inbound call, the outbound calls starts working.

CentOS 5.4
asterisk 1.6.0.21-1
dahdi 2.2.1.-1

Can anybody help me to identify what is the possible cause of problem?

Thanks,

Walter.

Re: [asterisk-users] Unable to create channel of type 'DAHDI' (cause 0- Unknown)

2010-01-28 Thread Karl Fife
I have had the exact same problem for over a year on my server sporting the 
TDM800 but NOT on my server with the TE212P.  Both servers run the same 
version of Linux, Asterisk and DHADI.

The problem has remained consistent through all versions of DAHDI 2.0.x 
through 2.2.0.2, and every version of Asterisk which I have I've tried which
includes various iterations of 1.6.0, 1.6.1, and 1.6.2.  Currently 1.2.6.1. 
Surprisingly I also observe that I can even compile  install NEW versions 
of Asterisk and/or DAHDI, and NOT observe the bug provided that I do NOT 
bounce the server.

A developer (not an asterisk developer) named Jim Duda posted this issue to 
the list back in October of 08.   (Asterisk 1.6.0-beta9  DAHDI 2.0.x 
originally for him).  After what he described as considerable effort he 
found that by changing one line in chan_dahdi.c the issue appeared to be 
resolved (below).  His simple patch (below) has works (for me too) as a 
stop-gap.

I posted this the DEV list back January of 09, and the issue was reopened 
and then closed as 'fixed' .  It would appear the issue needs to be 
re-reopened, as it's now appearing less specific to my hardware or 
configuration.

https://issues.asterisk.org/view.php?id=13786
Duplicate issue to 13927

If I do not patch chan_dahdi (below), this is what I (still) observe:
ONLY after a system reboot, any attempt(s) to dial from a device attached to 
an FXS port on my TDM800P, result in the following error :

WARNING[2975]: app_dial.c:1502 dial_exec_full: Unable to create channel of 
type 'DAHDI' (cause 0 - Unknown)
  == Everyone is busy/congested at this time (1:0/0/1)

BUT after the first INBOUND call to any FXO port on the device, the FXS port 
works normally until the next reboot.

(Asterisk 1.6.2.1  DAHDI 2.2.0.2 ( earlier ) Centos 2.6.18-164.11.1.el5 #1 
SMP Wed Jan 20 07:39:04 EST 2010 i686 i686 i386 GNU/Linux

Does anyone else observe this?  Could it be specific to certain 
(mis)configurations?  It's possible that others have the issue but do not 
know it.  With any inbound call volume it may be nearly transparent :-)

Shaun Ruffel of Digium pointed me to

2008-10-10 Thread Brendan Martens
The reason for this is that 1.6.0 does not support dahdi. It was a  
mistake when it was listed as an included feature. The documentation  
for it has been removed in 1.6.0.1. If you need dahdi you need to go  
to 1.6.1.

This is documented in this changelog:

 I've upgraded to 1.6.0 with dahdi 2.0.

 For some reason my outbound dahdi calls are not going through.
 At some point, it starts to work, but I don't know what the
 trigger is.  Out of the blue, outbound calls start to work.

 I had been using asterisk-1.6-beta9 with zaptel without any
 problems.

That is incorrect. There was one small feature (the 'dahdichan'
configuration option, used when creating a new-style chan_dahdi.conf
instead of the format used by zapata.conf) that was mistakenly included
in the sample config file in 1.6.0, which has how been removed in

1.6.0 fully supports DAHDI, and does not support Zaptel at all.

Inbound calls on DAHDI work fine.

At some point, outbound starts working.  I just cannot figure out what
the trigger is.  At first, I thought the trigger was receiving at least
one inbound call.  But that isn't always true.  Once it starts working,
it seems to continue until a restart.

Everything looks normal.  I'm having trouble with outbound calls
on channel 4 (attached to the PSTN).

 The reason for this is that 1.6.0 does not support dahdi. It was a  
 mistake when it was listed as an included feature. The documentation

 to 1.6.1.
 
 That is incorrect. There was one small feature (the 'dahdichan'
 configuration option, used when creating a new-style chan_dahdi.conf
 instead of the format used by zapata.conf) that was mistakenly included
 in the sample config file in 1.6.0, which has how been removed in
 1.6.0.1. The dahdichan config option is supported in 1.6.1.
 
 1.6.0 fully supports DAHDI, and does not support Zaptel at all.

[asterisk-users] Unable to create channel of type 'DAHDI' (cause 0 - Unknown)

2008-10-10 Thread Jim Duda
Does anyone know what this error message means?

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

I've upgraded to 1.6.0 with dahdi 2.0.

For some reason my outbound dahdi calls are not going through.
At some point, it starts to work, but I don't know what the
trigger is.  Out of the blue, outbound calls start to work.

I had been using asterisk-1.6-beta9 with zaptel without any
problems.

Thanks,

Jim
