328 Matrix ETERNITY NE System Manual
You must configure the Trusted IP Address/es table to allow incoming calls from specific IP addresses on this SIP
Trunk.
If you select SIP Trunk Mode as Peer to Peer and you do not configure this table, by default, all incoming calls on
this SIP Trunk will be rejected.
If you select SIP Trunk Mode as Proxy and you do not configure this table, by default, incoming calls will be
allowed only from the Proxy/Registrar Server Address or Outbound Proxy Address configured for this SIP Trunk. All
other calls on this SIP Trunk will be rejected.
• Click Trusted IP Address/es to expand.
If you have selected SIP Trunk mode as Peer to Peer, configure the following.
• Enable Allow from all IP Addresses check box, if you want to allow incoming calls on this SIP Trunk from
all IP Addresses. Default: Disabled.
• Enable Apply Digest Authentication check box, if you want to allow incoming calls from callers only after
the callers authenticate themselves with their User ID and Password. If the caller does not enter valid
credentials in two attempts, the system will reject the call.
If you have enabled Allow from all IP Addresses check box, Apply Digest Authentication check box will be
enabled automatically. You must configure the Digest Authentication table.
To configure the table, click the Settings icon. The Digest Authentication table opens in a new window. For
instructions, see “Digest Authentication”.
• Enable Consider Peer to Peer Table for Trusted IP Address check box, if you also want to allow
incoming calls from the domain names or IP Addresses configured in the Peer to Peer table. Default:
Enabled. To know more about Peer to Peer table, see “Peer-to-Peer Calling”.
If you have selected SIP Trunk mode as Proxy or Peer to Peer, configure the Trusted IP Address/es table.
• The first entry in the table will display the Proxy/Registrar Server Address:Port or Outbound Proxy
Address: Port as configured for this SIP Trunk, when SIP Trunk mode is selected as Proxy.
• For the Index numbers 1 to 10, enter the IP Address and the corresponding Port from which you want to
allow incoming calls.
Do not configure the port, if you want to allow incoming calls from all the ports for a particular IP Address.
• Click Submit to save your entries and close the window.
