Mediant 1000B Gateway & E-SBC
Parameter Description

When option [2] or [3] 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] or [3] 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 498.

[ISDNRxOverlap]
Same as the description for parameter ISDNRxOverlap_x, but for all
trunks.

[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: The parameter is applicable to ISDN Overlap mode only when
dialed numbers are sent using Q.931 Information messages.
[ConnectedNumberType] 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).

[ConnectedNumberPlan]
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).

isdn-tnl-tel2ip
[EnableISDNTunnelingTel2IP

Enables ISDN Tunneling.
 [0] Disable (default).
 [1] Using Header = Enable ISDN Tunneling from ISDN to SIP
using a proprietary SIP header.
