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,
based on RFC 3578. The device interworks ISDN to SIP by sending
digits each time they are received (from Setup and subsequent Info
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 275.
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
