ISDN Flexible Behavior Parameters

ISDN protocol is implemented in different Switches / PBXs by different vendors. Several implementations vary a little from the specification. Therefore, to provide a flexible interface that supports these ISDN variants, the ISDN behavior parameters are used.

ISDNInCallsBehavior	2048 = Sends Channel ID in the first response to an incoming Q.931 Call Setup
[Incoming Calls Behavior]	message. Otherwise, the Channel ID is sent only if the gateway requires to change
	the proposed Channel ID (default).
	8192 = Sends Channel ID in a Q.931 Call Proceeding message.
	65536 = Includes Progress Indicator (PI=8) in Setup ACK message, if an empty
	called number is received in an incoming Setup message. Applicable to overlap
	dialing mode. The parameter also directs the gateway to play a dial tone (for
	‘DialToneDuration’), until the next called number digits are received.
	262144 = NI-2 second redirect number – Users can select and use (in Invite
	messages) the NI-2 second redirect number, if two redirect numbers are received in
	Q.931 Setup for incoming Tel IP calls.
	Note: To configure the gateway to support several ‘ISDNInCallsBehavior’ features,
	summarize the individual feature values. For example to support both ‘2048’ and
	‘65536’ features, set ‘ISDNInCallsBehavior = 67584.
ISDNIBehavior	1 = Q.931 Status message isn’t sent if Q.931 received message contains an
[Q.931 Layer Response	unknown/unrecognized IE(s). By default the Status message is sent. This parameter
Behavior]	applies only to PRI variants in which sending of Status message is optional.
	2 = Q.931 Status message isn’t sent if an optional IE with invalid content is received.
	By default the Status message is sent. This parameter applies only to PRI variants in
	which sending of Status message is optional.
	4 = Accepts unknown/unrecognized Facility IE. Otherwise, (default) the Q.931
	message that contains the unknown Facility IE is rejected. This parameter applies to
	PRI variants where a complete ASN1 decoding is performed on Facility IE.
	128 = Connect ACK message is sent in response to received Q.931 Connect.
	Applicable only to Euro ISDN User side outgoing calls. Otherwise, the Connect ACK
	is not sent (default).
	512 = Enables to configure T1 NFAS Interface ID (refer to the parameter
	‘ISDNNFASInterfaceID_x’). Applicable to 4/5ESS, DMS, NI-2 and HKT variants.
	2048 = Always set the Channel Identification IE to explicit Interface ID, even if the B-
	channel is on the same trunk as the D-channel. Applicable to 4/5ESS, DMS and NI-2
	variants.
	65536 = Applicable to ETSI, NI-2 and 5ESS. The calling party number (octet 3a) is
	always present even when presentation and screening are at their default.
	131072 = Clears the call on reception of Q.931 Status with incompatible state.
	Otherwise, (default) no action is taken.
	Note: To configure the gateway to support several ‘ISDNIBehavior’ features,
	summarize the individual feature values. For example to support both ‘512’ and
	‘2048’ features, set ‘ISDNIBehavior = 2560’.
