Trust Mode

In Superuser mode, type configure terminal and press Enter.

ORACLE# configure terminal

Type session-router and press Enter to access the system-level configuration elements.

ORACLE(configure)# session-router

Type sip-interface and press Enter. The system prompt changes to let you know that you can begin configuring individual parameters.

ORACLE(session-router)# sip-interface
ORACLE(sip-interface)#

From this point, you can configure SIP interface parameters. To view all sip-interface parameters, enter a ? at the system prompt.

If configuring an existing interface, enter the select command to select the interface.

trust-mode—Select the trust mode for this SIP interface. The default value is all. The valid values are:

all—Trust all previous and next hops except untrusted session agents
agents-only—Trust only trusted session agents
realm-prefix—Trusted only trusted session agents or address matching realm prefix
registered—Trust only trusted session agents or registered endpoints
none—Trust nothing

Save and activate your configuration.

The following example shows the trust-mode set to none. The remaining SIP interface options are omitted for brevity.
