Call Processing
What’s this?
When the call originates on source port, call will be routed on the
destination port through some process. This process for routing the
call on the destination port is called Call Processing.
• When the call originates on a FXS port, it is required to place the
call on the SIP Account.
• When the call originates on the SIP Account, it is required to route
the call on the FXS port.
• Call cannot be placed directly on the destination port because there
are multiple ports, supported by the gateway.
• Thus, some process is required in the Gateway through which it
can decide on which port the call will be placed when the call
originates on the port.
How it works?

FXS to SIP Call:
• Before call processing, the gateway will check ‘Class of Service’
and ‘Supplementary Features’ to allow the feature.
• After you go OFF-Hook, from the Phone connected at FXS port, the
system will first check whether that FXS port is enabled or disabled.
