Address for Incoming SIP Message — As per Trusted IP Address table, As per Peer-to-Peer table or Any.
• If you select As per Trusted IP Address table option, the system matches the IP Address: Port received
in the INVITE message (Source IP address from the Network layer and Source Port from the Transport

to the desired destination. Else the call will be rejected.
You must configure the Trusted IP Address Table to receive incoming calls on this SIP Trunk. If you do
not configure this table, incoming calls on this SIP Trunk will be rejected.
You can configure maximum 10 entries in the Trusted IP Address table.
