This feature provides support for interworking date and time between SIP and Euro-
ISDN:
• SIP-to-ISDN interworking: The date and time from the received SIP 200 OK
message is included in the ISDN Connect message by the addition of the
Date/Time Information Element (IE).
• ISDN-to-SIP interworking: The date and time in the Date/Time IE received from
the ISDN Connect message is interworked to the SIP Date header and sent to the
IP network.
This feature is essential for synchronization between the PSTN (for example, PBX)
and the IP network.
Note: The Date/Time IE can only be sent by an ISDN network-side trunk.

Management Protocol

This feature provides support for interworking the ISDN Setup message with an
offhook indicator IE to SIP INVITE’s Request-URI header (in addition to the existing
support for the Contact header). Upon receipt of an ISDN offhook indicator IE from the
PSTN side, the device sends a SIP INVITE to the IP side with the parameters
“tgrp=hotline” or “tgrp=hotline-ccdata” included in the Request-URI and Contact
headers.
This feature is configured using the new option, “Hotline Extended” (4) of the existing
UseSIPTgrp parameter.
Note: This feature is applicable to Department of Defense (DoD) applications,
according to the UCR 2008 Change 1 specification.
