My problem is that I cannot make two simultaneous calls through the fxo ports. On my dashboard I can see that I have 1/2 fxo trunks available. When I go to trunks I see that in fxo channel group 0, fxo-2 is not in the selected list. When I add it and reboot I can see that there are 2/2 fxo lines available but I still can only make only 1 call.
