Call Progress Tones 
Using these settings, user can configure tone frequencies according to user 
preference. By default, the tones are set to North American frequencies. Frequencies 
should be configured with known values to avoid uncomfortable high pitch sounds. 
ONis the period of ringing (ON time in ms) while OFF is the period of silence. In order 
to set a continuous ring, OFF should be zero. Otherwise it will ring ON ms and a pause 
of OFF ms and then repeat the pattern.

Failover to FXO Gateway 
This feature allows users to place an outbound PSTN call in case there is a loss of an 
active registration (SIP server unreachable) of all FXS profiles. If set to “YES”, when 
GXW42XX recognizes a loss of registration, all outgoing calls will be routed to an FXO 
gateway. 
The use of this option presumes a configured GXW410x or another FXO gateway with 
an active PSTN line connection.
