3.6.1 VoIP Authentication Overview
The VoIP Authentication feature on the gateway provides a means for validating SIP devices
requesting services of the gateway (Inbound VoIP) and for the gateway to respond to authentication
requests when the gateway is requesting services from a SIP device (Outbound VoIP). To use this
feature, navigate to the Configuration-->Vo I P-->Authentication link via the Media Gateway’s user
interface.
3.6.1.1 Inbound VoIP (Server)
Inbound VoIP refers to the gateway acting as a SIP server and receiving SIP methods. Inbound
VoIP may be used to prevent unauthenticated SIP agents from routing calls through the gateway.
3.6.1.2 Inbound VoIP Configuration
Figure 13 is a sample screen shot of the Inbound VoIP Configuration Web page:

Inbound Authentication Enabled - Determines if the gateway will challenge a peer upon
receiving a SIP method. If Yes and the appropriate Method to Challenge is selected through the
checkbox, the gateway will challenge the peer upon reception of the method by sending a SIP 401
response along with the Gateway Realm.
Gateway Realm - Defines a protection space of the gateway. Associated with the Gateway Realm
is a series of User Name and Password pairings. The gateway may challenge a peer with the Realm.
The peer must have knowledge of the User Name and Password pairing in order to be authenticated
by the gateway.
