Hello I have a Cisco 881 VGW with 4 fxs ports and 1 fxo port.
I am trying to configure a fxs port so i can plug a ringer into it.
I have tried to configure the port as a loop start and also a pots port
on the loop config i get registartion rejected and on the pots port config i just get unknow.
Any points in the right direction would be greatly appreciated
