6.1.2 PhoneList
The PhoneList tab lists and configures the local phone parameters. This section configures the SIP
parameter required to build SIP messages for different phones attached to different phone ports of the
gateway to send signaling information to the other party. When a call dials in, it will see if the called
number maps any of the entries in the phone port list. If no entry is matched, the call request is dropped.
The gateway supports two FXS ports for phone service and their two entries, Port No 1 and Port No 2, in
the phone list.
