The VoIP Gateway deals with the calls from FXO ports in two ways, Direct Inward Dial
(DID) mode and non-DID mode. In DID mode, when there is an incoming call from FXO
ports, the VoIP Gateway forwards the call directly to the SIP proxy server.
In non-DID mode, when an incoming call from FXO port is detected, the VoIP Gateway
then presents a dial tone and waits for the caller to dial the destination number before
setting up the call. The VoIP Gateway can register up to 4 phone numbers to the SIP server.
By registering multiple phone numbers, you can assign each FXO port a unique phone
number, so that calls from remote SIP devices are terminated to a specific FXO port ac-
cording the destination phone number the remote device encapsulates in the SIP header.
Alternatively, you can group multiple FXO ports into a single hunt group and assign it a
unique phone number. The VoIP Gateway will terminate calls destined to a hunt group to
the first free FXO port in that hunt group.
