GSM dongle trunk customization - start and stop the dongle

The module is called DISA? Did you go to module admin in FreePBX and do a check for updates?

Thru GUI
I am getting the following:
Warning: Error retrieving updates from online repository(s) (http://mirror1.freepbx.org,http://mirror2.freepbx.org). Online modules are not available.

Skyking,

i checked your old posts and i fixed the DNS issue and i can install the DISA module now. thank you for the help.

if you don’t mind i have another question.
why i can reverse the call process? meaning, someone overseas will call the SIM number and forward the call to the US sip number?
