Zap Channel Problem

Hi to all,

Is any body knows how to find whether zap channel is busy or not. I tried out many things. But I don’t get success.

If any body know or previously done that then please tell me in details i.e. about extensions.conf or other files.

My current extensions.conf file is as follows,

[quote][MyContext]
exten => s,1,GotoIf($["${DIALSTATUS}" = “BUSY”]?4:2)
exten => s,2,AGI(Somefile.php)
exten => s,3,Hangup()
exten => s,4,AGI(OnBusy.php)
exten => s,5,Hangup()[/quote]

My current zaptel-channel.conf file as follows,

[quote];;; line="6 WCTDM/0/5 FXSKS"
signalling=fxs_ks
callerid=asreceived
group=0
channel => 5
context=MyContext[/quote]

In above extensions.conf file you see that on second line I used DIALSTATUS Variable but ianplain told me that in past post, variable DIALSTATUS is define when call ended. So, I think above idea that I used is wrong or missing something in that. So, Please suggest me nice solution for how to detect channel busy or not.

Please Share your valuable knowledge.

Regards,
Deepen

you can use dialstatus variable like this

exten => s,1,Dial(${ZAP/1/123456,,T) exten => s,n,Goto(s-${DIALSTATUS},1) exten => s-NOANSWER,1,Hangup exten => s-CONGESTION,1,Congestion exten => s-CANCEL,1,Hangup exten => s-BUSY,1,Busy exten => s-CHANUNAVAIL,1,Hangup

according to this error

your problem is in your zap channel and your zap channel not properly loaded
