[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).
Enable ISDN Tunneling
Tel to IP
isdn-tnl-tel2ip
[EnableISDNTunnelingT
el2IP]
Enables ISDN Tunneling.

[0] Disable (default).

[1] Using Header = Enable ISDN Tunneling from ISDN to SIP using
a proprietary SIP header.

[2] Using Body = Enable ISDN Tunneling from ISDN to SIP using a
dedicated message body.
When ISDN Tunneling is enabled, the device sends all ISDN messages
using the correlated SIP messages. The ISDN Setup message is
tunneled using SIP INVITE, all mid-call messages are tunneled using
SIP INFO, and ISDN Disconnect/Release message is tunneled using
SIP BYE messages. The raw data from the ISDN is inserted into a
proprietary SIP header (X-ISDNTunnelingInfo) or a dedicated message
body (application/isdn) in the SIP messages.
Note:

For this feature to function, you must set the parameter
ISDNDuplicateQ931BuffMode to 128 (i.e., duplicate all messages).

ISDN tunneling is applicable for all ISDN variants as well as QSIG.
Enable ISDN Tunneling
IP to Tel
isdn-tnl-ip2tel
[EnableISDNTunnelingIP
2Tel]
Enables ISDN Tunneling for IP-to-Tel calls.

[0] Disable (default)

[1] Enable ISDN Tunneling from IP to ISDN
When ISDN Tunneling is enabled, the device extracts raw data received
in the proprietary SIP header, x-isdntunnelinginfo, or a dedicated
message body (application/isdn) in the SIP message and then sends
the data in an ISDN message to the PSTN.
If the raw data in this SIP header is suffixed with the string "ADDE",
then the raw data is extracted and added as Informational Elements (IE)
in the outgoing Q.931 message. The tunneling of the x-isdntunnelinginfo
SIP header with IEs is converted from INVITE, 180, and 200 OK SIP
messages to Q.931 SETUP, ALERT, and CONNECT respectively.
