ISDN DivertingLegInformation2 Facility
SmartWare is now able to extract the redirecting information from the DiverstingLegInformation2 Facility and
to provide them to the call control. In the other direction, the redirecting information can be sent as
DiverstingLegInformation2 Facility in addition to the Redirecting Number Information Element.
Transmit Direction
Mode: interface isdn <interface>
Receive Direction
Mode: interface isdn <interface>
T1 Caller-Name Support
The ISDN implementation now supports reception and transmission of the caller-name on T1 links as it is
used in NI2 networks according to Bellcore GR-1367-CORE. Transmission of the caller-name is part of the
Calling Name Delivery (CNAM) service.
In previous build series (R3.20), the caller-name was already supported for DSS-1 networks using User-User
information elements and for Q.SIG (PSS-1) networks using FACILITY messages. Now the caller-name is also
supported for NI2 networks following the Bellcore standard.
As a prerequisite, the caller-name feature must be enabled on each ISDN interface in the CS context separately.
This command now has additional arguments to configure the SETUP retention as follows:
In NI2 networks an incoming ISDN SETUP message may contain a NameInfomationFollowing indication
instead of the name. This means that the calling-party name is not available yet, but will be sent later, for exam-
ple, after the dictionary database lookup in progress succeeded. If such an incoming ISDN call is internally
routed to another network (e.g. to a SIP network or to a ISDN DSS-1 network), we must know the name
before sending the initial INVITE or SETUP message towards the destination network. Therefore we must
retain the SETUP message of the incoming ISDN call until the name is present. The caller-name command
now allows you to configure the behaviour of this SETUP retention mechanism. There are three possible
options:
• caller-name ignore-absence <timeout>: This configuration command specifies the behaviour for incoming
ISDN calls. When a NameInformationFollowing indication is received with the SETUP message, the call-
initiation is retained until the name is received or until this timeout elapses. After that, the call is forwarded
to the configured destination interface. When forwarding a call without a caller-name to a SIP network,
please note that there is no chance to send the caller-name later over SIP.
