Table 1-6: New SBC Parameters for Release 6.2

Parameter	Description
SBC No Answer Timeout	Defines the timeout (in seconds) to SBC outgoing (outbound
[SBCAlertTimeout]	IP routing) SIP INVITE messages. If the called IP party does
	not answer the call within this user-defined interval, the
	device disconnects the session. The device starts the
	timeout count upon receipt of a SIP 180 Ringing response
	from the called party. If no other SIP response (for example,
	200 OK) is received thereafter within this timeout, the call is
	released.
	The valid range is 0 to 3600 seconds. the default is 600.
SBC GRUU Mode	Determines the Globally Routable User Agent (UA) URI
[SBCGruuMode]	(GRUU) support (according to RFC 5627).
	[0] None = No GRUU is supplied to users.
	[1] As Proxy = The device provides same GRUU types as
	the proxy provided the device’s GRUU clients. (default)
	[2] Temporary only = Supply only temporary GRUU to
	users. (Currently not supported.)
	[3] Public only = The device provides only public GRUU to
	users.
	[4] Both = The device provides temporary and public
	GRUU to users. (Currently not supported.)
SBC Max Forwards Limit	Defines the value of the Max-Forwards SIP header.
[SBCMaxForwardsLimit]	The valid value range is 1-70. The default is 10.
	This parameter affects the Max-Forwards header in the
	received message, as follows:
	If the received header’s original value is 0, the message is
	not passed on and is rejected.
	If the received header’s original value is less than the
	user-defined parameter, the header’s value is
	decremented before being sent on.
	If the received header’s original value is greater than the
	user-defined parameter, the header’s value is replaced by
	the user-defined parameter’s value
Minimum Session-Expires	Defines the minimum amount of time (in seconds) between
[SBCMinSE]	session refresh requests in a dialog before the session is
	considered timed out. This value is conveyed in the SIP Min-
	SE header.
	The valid range is 0 (default) to 1,000,000 (where 0 means
	that the device does not limit Session-Expires).
