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
[Tel2IPDefaultRedirectReason]
Default redirect reason for Tel-to-IP calls when no redirect
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.

softswitch.
