yes, i have the same config for both card 4-FXO
the first 4 port is connected to 4 analog lines (to telecom company) and all call are fine from inside to outside and from outside from inside.
but the seconde card 4-FXO are connected to 4 gateway GSM (to mobile phone company), i can make the call from inside to other number in the world, but i can't receive the call( just ring and han up when i tray to respond.
this command is to solve another problem, but i have testd this command without result.
yes i have tested the port 0/3/X , they work fine with analog line.
And if the port isn't good i can't make calls from inside to outsider vis this ports.

That looks like battery reversal is occurring and the Cisco gateway is disconnecting the call. Is this with "no battery-reversal" applied to the voice port?
