hello friends,
atlast i got success with the cpl scripts
but one small problem is coming i.e
we have three numbers 214103,215104,216105
i have written script for the 214103 like this where if any body call s to 214103 it should redirect the call to the 215104 so when 216105 calls to 214103 the call has to goto the 215104 with out disturbing the 214103 but here the call is going to the twol numbers 214103,215104 who ever picks up first the second call is being hanged up.
cpl script is
