Hi All,
Thanks for your suggestions.
I am using DeadAgi application for origination of calls, i have set same
context to Transfer context.
I have also added Tt options in dial options.
When I am receiving calls to grandstream phone,
I am using transfer button to transfer the call, but it is not transfering
with AGI application,
Can anyone provides me suggestions for blind transfer with AGI application.

My Dialplan is given Below. I have used PHPAGI for the origination of calls.
[bt200]
exten => _X.,1,Set(__TRANSFER_CONTEXT=bt200)
exten => _X.,n,DeadAGI(testing_agi/testing.php)
exten=> h,1,NoOp(${DIALSTATUS})


Thanks,
Max Alex
Voip Developer
