1.11.4 PSTN New Parameters

The table below describes the new PSTN parameters for Release 6.2.

Notes: These parameters are applicable only to the Gateway application.

Table 1-8: New PSTN Parameters for Release 6.2
Parameter	Description
[ISDNNSBehaviour2]	Bit-field to determine several behavior options, which influences
	the behavior of the Q.931 protocol. When this bit is set to
	NS_BEHAVIOUR2_ANY_UUI (0x0008), any User to User
	Information Element (UUIE) is accepted for any protocol
	discriminator. This feature is useful for interoperability with non-
	standard switches.
Tel2IP Default Redirect Reason	Default redirect reason for Tel-to-IP calls when no redirect
[Tel2IPDefaultRedirectReason]	reason (or “unknown”) exists in the received Q931 ISDN Setup
	message. The device includes this default redirect reason in the
	SIP History-Info header of the outgoing INVITE.
	If a redirect reason exists in the received Setup message, this
	parameter is ignored and the device sends the INVITE message
	with the reason according to the received Setup message. If this
	parameter is not configured (-1), the outgoing INVITE is sent
	with the redirect reason as received in the Setup message (if
	none or “unknown” reason, then without a reason).
	[-1]Not Configured (default) = Received redirect reason is
	not changed
	[1] Busy = Call forwarding busy
	[2] No Reply = Call forwarding no reply
	[9] DTE Out of Order = Call forwarding DTE out of order
	[10] Deflection = Call deflection
	[15] Systematic/Unconditional = Call forward unconditional

BRI-to-SIP Supplementary Services Codes for Call Forward Note: Upon receipt of an ISDN Facility message for call forward from the BRI phone, the device sends a SIP INVITE to the softswitch with a user-defined code in the SIP To header, representing the reason for the call forward.

Call Forward Unconditional	Prefix code for activating Call Forward Unconditional sent to the
[SuppServCodeCFU]	softswitch.
	The valid value is a string. The default is an empty string.
	Note: The string must be enclosed in single apostrophe (e.g.,
	‘*72’).
Call Forward Unconditional	Prefix code for deactivating Call Forward Unconditional
Deactivation	Deactivation sent to the softswitch.
[SuppServCodeCFUDeact]	The valid value is a string. The default is an empty string.
	Note: The string must be enclosed in single apostrophe (e.g.,
	‘*72’).
