Version 7.2 1169 Mediant 500L Gateway & E-SBC
User's Manual 69. Configuration Parameters Reference
Parameter Description
according to RFC 3578. The device sends the first received digits
from the ISDN Setup message to the IP side in the initial INVITE
message. For each subsequently received ISDN Info Q.931
message, the device sends the collected digits to the IP side in re-
INVITE messages.
 [3]
Through SIP INFO =Interworking of ISDN Overlap Dialing to SIP
according to RFC 3578. The device sends the first received digits
from the ISDN Setup message to the IP side in the initial INVITE
message. For each subsequently received ISDN Info Q.931
message, the device sends the collected digits to the IP side in
INFO messages.
Note:
 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 496.

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 o
ther 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 C
onnected 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.
