[Asterisk-Users] NOTICE[507921]: app_dial.c:742 dial_exec: Unable to create channel of type 'Zap'

[U. Abdullah Sheikh]

Hi Asterisk-ians!

Need all of your help. I am stuck with this issue for last few days. I have 
one X100P installed in my system. My Asterisk is registered with another 
Asterisk Server/SIP provider as client and the call is successfully received 
by my Asterisk server (named as starwars).

Now, the extentions.conf file states, the incoming INTO * should go out to 
fxo as below:

exten => s,1,Dial(Zap/1/403142142)
exten => s,2,Dial(Zap/1/403132663)
exten => s,3,hangup

whereas other file config is as below:

zapata.conf
[channels]
relaxdtmf=yes
callwaiting=yes
callwaitingcallerid=yes
threewaycalling=yes
transfer=yes
cancallforward=yes
usecallerid=yes
echocancel=yes
echocancelwhenbridged=yes
rxgain=0.0
txgain=0.0
immediate=yes
context=bell
signalling=fxs_ks
callerid=asreceived
channel => 1

zaptel

fxsks=1
loadzone=us
defaultzone=us

sip.conf
register => 7062210:9211:7062210 at 192.168.7.16

[MyService]
type=peer
username=7062210
fromuser=7062210
secret=9211
host=192.168.7.16
context=incoming
fromdomain=sipdom.inf
nat=no
canreinvite=no
dtmfmode=inband


so whenever the call comes in from service provider's asterisk to my 
starwars asterisk, I get the error messages captured below:
