User's Manual
INVITE message. For each subsequently received ISDN Info
Q.931 message, the device sends the collected digits to the IP
side in INFO messages.
Notes:

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 348.
Same as the description for parameter ISDNRxOverlap_x, but for
all trunks.
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.
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).
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).
Enables ISDN Tunneling.

[0] Disable (default).
