Hi List,
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.
Problem :
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.
