Field	Description
Enable H.323 device	Check the box to turn on H.323 device authentication.
authentication	Click Device authentication settings to go to the Device Authentication
	page and add authentication credentials (see Device Authentication).
SIP Settings
Enable SIP signaling	Enables the system to receive Session Initiation Protocol (SIP) calls.
	Caution: Disabling SIP terminates any existing SIP calls. When you click
	Update, the system prompts you to confirm.
Enable ANAT support	Configures the system to pass through Alternative Network Address Types
	(ANAT) signaling (RFC 4091 and RFC 4092) in the Session Description
	Protocol (SDP) for the purpose of negotiating IP version in a dual-stack (IPv4
	+ IPv6) environment.
Authorized ports
Unencrypted SIP port	To permit unencrypted SIP connections, select either TCP or UDP/TCP from
	the list. Select None to disallow unencrypted SIP connections.
	We recommend using the default port number (5060), but you can use any
	value from 1024 to 65535 that’s not already in use and is different from the
	TLS port and from any “unauthorized” or “guest” ports that your SBC(s) may
	be configured to use for calls to the system.
Enable authentication	Check the box to turn on SIP device authentication for unencrypted SIP.
	Click the Device authentication settings link to go to the Device
	Authentication page to configure SIP device authentication and add device
	authentication credentials (see Device Authentication). The settings on that
	page determine:
	• The realm used for authentication.
	• Whether the Call Server responds to unauthenticated requests with 401
	(Unauthorized) or 407 (Proxy Authentication Required).
TLS port	Specifies the port number the system uses for TLS.
	We recommend using the default port number (5061), but you can use any
	value from 1024 to 65535 that’s not already in use and is different from the
	UDP/TCP port and from any “unauthorized” or “guest” ports that your SBC(s)
	may be configured to use for calls to the system.
	If SIP signaling is enabled, TLS is automatically supported. Unless
	unencrypted SIP connections are specifically permitted, TLS must be used.
Enable authentication	Check the box to turn on SIP device authentication for encrypted SIP.
	Click the Device authentication settings link to go to the Device
	Authentication page to configure SIP device authentication and add device
	authentication credentials (see Device Authentication). The settings on that
	page determine:
	• The realm used for authentication.
	• Whether the Call Server responds to unauthenticated requests with 401
	(Unauthorized) or 407 (Proxy Authentication Required).
