Authentication Select one: 
•Handle authentication — When it receives a 401 
(Unauthorized) response from this SIP peer, the 
Call Server presents its authentication credentials. 
•Pass authentication — When it receives a 401 
response from this SIP peer, the Call Server passes 
it to the source of the request.

an H.323 endpoint (a gateway call). If the Call Server 
can’t provide the required credentials, the call fails.

407 (Proxy Authentication Required) response from

entry is valid and the user name. Click Add to add

listed here. If there is none with the correct realm, it 
looks for an appropriate entry on the Device 
Authentication page.

associated with this SIP peer and lets you add, edit, or
