There is no update on this, it has not been looked at as it was closed automatically. Additionally you are using an unsupported version of Asterisk (1.8) you will need to upgrade to the latest Asterisk 11 and if the problem persists then provide information.
By: Ravi Kumar (ravi_448) 2016-02-19 00:41:40.245-0600

Thanks for the response , I will upgrade to version 11 and get back to you if I still face the same problem.
