Table 69-59: ISDN and CAS Interworking Parameters
Parameter Description
ISDN Parameters
Send Local Time To ISDN
Connect
[SendLocalTimeToISDNCon
nect]
Determines the device's
handling of the date and time sent in the ISDN
Connect message (Date / Time IE) upon receipt of SIP 200 OK
messages.
 [0] Disable = (Default) If the SIP 200 OK includes the Date header,
the device sends its value in the ISDN Connect Date / Time IE. If
the 200 OK does not include this header, it does not add the Date /
Time IE to the sent ISDN Connect message.
 [1] Enable = If the SIP 200 OK includes the Date header, the
device sends its value (i.e. date and time) in the ISDN Connect
Date / Time IE. If the 200 OK does not include this header, the
device uses its internal, local date and time for the Date / Time IE,
which it adds to the sent ISDN Connect message.
 [2] Always Send Local Date and Time = The device always sends
its local date and time (obtained from its internal clock) to PBXs in
