External SIP Peer Device Management

Table 5-14Add External SIP Peer dialog box

	Field	Description
	Authentication	On this tab, you can configure SIP digest
		authentication, as specified in RFC 3261, for this SIP
		peer and add or edit authentication credentials.
		SIP authentication must be enabled and configured on
		the Device Authentication page.
		Note: The digest authentication settings for this peer
		are used only in conjunction with a dial rule specifying
		the Resolve to external SIP peer action. If another dial
		rule action, such as Resolve to external address, is
		applied to the call, there is no association to this peer
		and its authentication settings aren’t used.
	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.
		Note: SIP authentication requests are never passed to
		an H.323 endpoint (a gateway call). If the Call Server
		can’t provide the required credentials, the call fails.
	Proxy authentication	Select one:
		•	Handle proxy authentication — When it receives a
			407 (Proxy Authentication Required) response from
			this SIP peer, the Call Server presents its
			authentication credentials.
		•	Pass proxy authentication — When it receives a 407
			response from this SIP peer, the Call Server passes
			it to the source of the request.
		Note: Authentication requests are never passed to an
		H.323 endpoint (a gateway call). If the Call Server can’t
		provide the required credentials, the call fails.
	(table of authentication	Lists the authentication credential entries defined for
	entries)	use with this SIP peer, showing the realm in which the
		entry is valid and the user name. Click Add to add
		authentication credentials.
		When choosing authentication credentials to present to
		this SIP peer, the Call Server looks first at the entries
		listed here. If there is none with the correct realm, it
		looks for an appropriate entry on the Device
		Authentication page.
	External Registration	Lists any outbound registration configurations
		associated with this SIP peer and lets you add, edit, or
		delete registrations. Multiple registrations may be
		associated with a SIP peer.
