Command Reference Guide Voice SIP Trunk Command Set
reject-external
Use the reject-external command to prevent inbound calls on the trunk from being routed back out of the
same trunk. Use the no form of this command to return to the default setting.
Syntax Description
No subcommands.
Default Values
No default values are necessary for this command.
Command History
Release 9.3 Command was introduced.
Functional Notes
In general, trunks are assigned to the user role, which means they terminate lines from a Telco provider. If
this is the case, reject-external should be enabled so that inbound calls on the trunk cannot be routed
back out of the same trunk. If the configuration is poor, inbound long distance calls could be routed back
out of the same trunk, causing the owner of the unit to be charged for long distance calls without his
knowledge. For network-role trunks and SIP-based trunks, this command should be disabled to allow calls
to be properly routed in the unit.
Usage Examples
The following example activates reject-external:
(config)#voice trunk t01 type sip
(config-t01)#reject-external
