[Asterisk-Users] Unable to create channel of type 'Zap'

Hi,

I just installed the asterisk and the X100P card.  I can receive calls from 
PSTN and it can ring on a Grandstream SIP Phone.  From the SIP Phone I can 
dial the demo extension on asterisk pbx.  The issue is as soon as I try to 
dial out 92714756 or another number I received the following message:

*CLI>     -- Executing Dial("SIP/1001-2b93", "Zap/g2/2714756") in new stack
Apr 20 02:27:40 NOTICE[245776]: app_dial.c:536 dial_exec: Unable to create 
channel of type 'Zap'
  == Everyone is busy at this time
    -- Executing Congestion("SIP/1001-2b93", "") in new stack
  == Spawn extension (from-sip, 92714756, 2) exited non-zero on 
'SIP/1001-2b93'

Zapata.conf is:

[channels]
callwaiting=yes
callwaitingcallerid=yes
threewaycalling=yes
transfer=yes
cancallforward=yes

echocancel=yes
echocancelwhenbridged=no

rxgain=0.0

extensions.conf
;
; Static extension configuration file, used by ; the pbx_config module. This 
is where you configure all your ; inbound and outbound calls in Asterisk.
;

;
; The "General" category is for certain variables.
;
[general]
;
; If static is set to no, or omitted, then the pbx_config will rewrite ; 
this file when extensions are modified.  Remember that all comments ; made 
in the file will be lost when that happens.

; XXX Not yet implemented XXX
;
static=yes
;
; if static=yes and writeprotect=no, you can save dialplan by ; CLI command 
'save dialplan' too ; writeprotect=no

; You can include other config files, use the #include command (without the
';')
; Note that this is different from the "include" command that includes 
contexts within ; other contexts. The #include command works in all asterisk 
configuration files.
;#include "filename.conf"

; The "Globals" category contains global variables that can be referenced ; 
in the dialplan with ${VARIABLE} or ${ENV(VARIABLE)} for Environmental 
variable ; ${${VARIABLE}} or ${text${VARIABLE}} or any hybrid ; [globals]
CONSOLE=Console/dsp                             ; Console interface for demo

;TRUNK=IAX2/user:pass at provider
;
; Any category other than "General" and "Globals" represent ; extension 
contexts, which are collections of extensions.
;
; Extension names may be numbers, letters, or combinations ; thereof. If an 
extension name is prefixed by a '_'
; character, it is interpreted as a pattern rather than a ; literal.  In 
patterns, some characters have special meanings:
;
;   X - any digit from 0-9
;   Z - any digit from 1-9
;   N - any digit from 2-9
;   [1235-9] - any digit in the brackets (in this example, 1,2,3,5,6,7,8,9)
;   . - wildcard, matches anything remaining (e.g. _9011. matches
;       anything starting with 9011 excluding 9011 itself)
;
; For example the extension _NXXXXXX would match normal 7 digit dialings, ; 
while _1NXXNXXXXXX would represent an area code plus phone number ; 
preceeded by a one.
;
; Contexts contain several lines, one for each step of each ; extension, 
which can take one of two forms as listed below, ; with the first form being 
preferred.  One may include another ; context in the current one as well, 
optionally with a ; date and time.  Included contexts are included in the 
order ; they are listed.
;
;[context]
;exten => someexten,priority,application(arg1,arg2,...)
;exten => someexten,priority,application,arg1|arg2...
;
; Timing list for includes is
;
;   <time range>|<days of week>|<days of month>|<months>
;
;include => daytime|9:00-17:00|mon-fri|*|* ; ; ignorepat can be used to 
instruct drivers to not cancel dialtone upon ; receipt of a particular 
pattern.  The most commonly used example is ; of course '9' like this:
;
;ignorepat => 9
; so that dialtone remains even after dialing a 9.

ZAPTEL.CONF
loadzone = us
#default = us

fxsks=1

Please, notice that "default=us" is commented since when I run ztcfg -vvv it 
gave me the following error:
root at knoppix:/etc# ztcfg -vvvv
Notice: Configuration file is /etc/zaptel.conf line 2: Unknown keyword 
'default'

1 error(s) detected

I commented the line 2 and run ztcfg again and it worked without errors.
May it has no relationship with the error describe above.


Thanks.
Jaime
