Data
Gain, impedance, ring current, and feed
NOTE
If the RBT played for the caller through the FXO port is too loud, the FXO port may fail to detect the busy
tone from the caller; therefore, if the caller hangs up before the call is answered, the called user still hears
the ring tone for a period. This problem can be solved by adjusting the send gain on the FXO interface.
