Mediant 3000
Parameter Description
Q.931 messages) to the IP, using subsequent SIP INVITE
messages.
Notes:

When option [2] is configured, you can define the minimum number
of overlap digits to collect before sending the first SIP message for
routing the call, using the MinOverlapDigitsForRouting parameter.

When option [2] is configured, even if SIP 4xx responses are
received during this ISDN overlap receiving, the device does not
release the call.

The MaxDigits parameter can be used to limit the length of the
collected number for ISDN overlap dialing (if Sending Complete is
not received).

If a digit map pattern is defined (using the DigitMapping or
DialPlanIndex parameters), the device collects digits until a match is
found (e.g., for closed numbering schemes) or until a timer expires
(e.g., for open numbering schemes). If a match is found (or the timer
expires), the digit collection process is terminated even if Sending
Complete is not received.

For enabling ISDN overlap dialing for IP-to-Tel calls, use the
ISDNTxOverlap parameter.

The x in the ini file parameter name denotes the trunk number,
where 0 is Trunk 1.

For more information on ISDN overlap dialing, see 'ISDN Overlap
Dialing' on page
316 .
[ISDNRxOverlap]
Same as the description for parameter ISDNRxOverlap_x, but for all
trunks.
Web/EMS: Mute DTMF
In Overlap
[MuteDTMFInOverlap]
Enables the muting of in-band DTMF detection until the device receives
the complete destination number from the ISDN (for Tel-to-IP calls). In
other words, the device does not accept DTMF digits received in the
voice stream from the PSTN, but only accepts digits from ISDN Info
messages.

[0] Don't Mute (default).

[1] Mute DTMF in Overlap Dialing = The device ignores in-band
DTMF digits received during ISDN overlap dialing (disables the
DTMF in-band detector).
Note: This parameter is applicable to ISDN Overlap mode only when
dialed numbers are sent using Q.931 Information messages.
[ConnectedNumberTyp
e] Defines the Numbering Type of the ISDN Q.931 Connected Number IE
that the device sends in the Connect message to the ISDN (for Tel-to-IP
calls). This is interworked from the P-Asserted-Identity header in SIP
200 OK.
The default is [0] (i.e., unknown).
[ConnectedNumberPla
n] Defines the Numbering Plan of the ISDN Q.931 Connected Number IE
that the device sends in the Connect message to the ISDN (for Tel-to-IP
calls). This is interworked from the P-Asserted-Identity header in SIP
200 OK.
The default is [0] (i.e., unknown).
Web/EMS: Enable ISDN
Tunneling Tel to IP
[EnableISDNTunneling
Tel2IP]
Enables ISDN Tunneling.

[0] Disable (default).

[1] Using Header = Enable ISDN Tunneling from ISDN PRI to SIP
using a proprietary SIP header.
