Thanks all for your inputs.. i tested all the above inuts but still same issue.

after trouble shooting i noticed that when i am calling from mobile or L.L to compnay number which is hittting gateway & the call is routing to operator if operator is not picking up the phone & enduser is disconnecting the call but operator phone is still ringing no disconnection is happing.

To alleviate this problem you should use connection plar opx.

you should also try cadence 500 500

Also note that most of the other commands you have configured, are useless.
