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.
ISDNIBehavior
[Q.931 Layer Response
Behavior]
 1 = Q.931 Status message isn’t sent if Q.931 received message contains
an unknown/unrecognized IE(s). By default the Status message is sent.
This parameter 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’.
ISDNOutCallsBehavior
[Outgoing Calls Behavior]
1024 = Numbering plan / type for T1 IPÆTel calling number are defined
according to the manipulation tables or according to RPID header (default).
Otherwise, the Plan / type for T1 calls are set according to the length of the
calling number
ISDNInCallsBehavior
[Incoming Calls Behavior]
2048 = Sends Channel ID in the first response to an incoming Q.931 Call
Setup message. Otherwise, the Channel ID is sent only if the gateway requires
changing 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 ‘TimeForDialTone'), 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 TelÆIP 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.
