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