<div>Hi List,</div>
<div> </div>
<div> I have configured TE121PF card in E1 mode. I am using asterisk 1.6 and freepbx 2.7. My card staus turn in to green and looks like sync with the service provider. My service provider is BSNL - India. I have one toll free number for incoming and one land line number for out going calls. </div>
<div> </div>
<div>Problem :</div>
<div> </div>
<div>If i am calling to the toll free number, i am getting the ring but that call is not reaching to my asterisk box. Both incoming and outgoing are failure. Please reffer the following informations for understand the issue further. </div>
