User's Manual 986 Document #: LTRT-89730
Mediant 3000
Parameter Description
the SIP 200 OK includes the Date header, the device ignores its
value.
Notes:
 This feature is applicable only to Tel-to-IP calls.
 For IP-to-Tel calls, the parameter is not applicable. Only if the
incoming ISDN Connect message contains the Date / Time IE does
the device add the Date header to the sent SIP 200 OK message.
Min Routing Overlap
Digits
[MinOverlapDigitsForRout
ing]
Defines the minimum number of overlap digits to collect (for ISDN overlap
dialing) before sending the first SIP message for routing Tel-to-IP calls.
The valid value range is 0 to 49. The default is 1.
Note: The parameter is applicable when the ISDNRxOverlap parameter
is set to [2] or [3].
ISDN Overlap IP to Tel
Dialing
[ISDNTxOverlap]
Enables ISDN overlap dialing for IP-to-Tel calls. This feature is part of
ISDN-to-SIP overlap dialing according to RFC 3578.
 [1] Through SIP = The device sends the first received digits from the
initial INVITE to the Tel side in an ISDN Setup message. For each
subsequently received re-INVITE message of the same dialog
session, the device sends the collected digits to the Tel side in ISDN
Info Q.931 messages. For each received re-INVITE, the device sends
a SIP 484 Address Incomplete response to maintain the current dialog
session and to receive additional digits from subsequent re-INVITEs.
 [2] Through SIP INFO = The device
sends the first received digits from
the initial INVITE to the Tel side in an ISDN Setup message and then
responds to the IP side with a SIP 183. For each subsequently
received SIP INFO message with additional digits of the same dialog
session, the device sends the collected digits to the Tel side in ISDN
Info Q.931 messages. For each received SIP INFO, the device sends
a SIP 200 OK response to maintain the current dialog session and to
receive additional digits from subsequent INFOs.
Note: When IP-to-Tel overlap dialing is enabled, to send ISDN Setup
messages without the Sending Complete IE, the ISDNOutCallsBehavior
parameter must be set to USER SENDING COMPLETE (2).
Enable Receiving of
Overlap Dialing
[ISDNRxOverlap_x]
Determines the receiving (Rx) type of ISDN overlap dialing for Tel-to-IP
calls, per trunk.
 [0] None = (Default) Disabled.
 [1] Local receiving = ISDN Overlap Dialing - the complete number is
sent in the INVITE Request-URI user part. The device receives ISDN
called number that is sent in the 'Overlap' mode. The ISDN Setup
message is sent to IP only after the number (including the Sending
Complete IE) is fully received (via Setup and/or subsequent Info Q.931
messages). In other words, the device
waits until it has received all the
ISDN signaling messages containing parts of the called number, and
only then it sends a SIP INVITE with the entire called number in the
Request-URI.
 [2] Through SIP = Interworking of ISDN Overlap Dialing to SIP
according to RFC 3578. The device
sends the first received digits from
the ISDN Setup message to the IP side in the initial INVITE message.
For each subsequently received ISDN Info Q.931 message, the device
sends the collected digits to the IP side in re-INVITE messages.
 [3] Through SIP INFO =Interworking of ISDN Overlap Dialing to SIP
according to RFC 3578. The device
sends the first received digits from
the ISDN Setup message to the IP side in the initial INVITE message.
