11.3 ISDN Overlap Dialing
Overlap dialing is a dialing scheme used by several ISDN variants to send and/or receive
called number digits one after the other (or several at a time). This is in contrast to en-bloc
dialing in which a complete number is sent.
The device can optionally support ISDN overlap dialing for incoming ISDN calls for the
entire device by setting the ini file parameter ISDNRxOverlap to 1, or per E1/T1 span by
setting ISDNRxOverlap_x to 1 (where x represents the number of the trunk). For
configuring ISDN overlap dialing using the Web interface, refer to ''Configuring the Trunk
Settings'' on page 73.
To play a Dial tone to the ISDN user side when an empty called number is received, set
ISDNINCallsBehavior = 65536 (bit #16). This results in the Progress Indicator to be
included in the SetupAck ISDN message.
The device stops collecting digits (for ISDN-to-IP calls) when:
The sending device transmits a ‘sending complete’ IE in the ISDN Setup or the
following INFO messages to signal that no more digits are going to be sent.
The inter-digit timeout (configured by the parameter TimeBetweenDigits) expires. The
default for this timeout is 4 seconds.
The maximum allowed number of digits (configured by the parameter MaxDigits) is
reached. The default is 30 digits.
A match is found with the defined digit map (configured by the parameter,
DigitMapping).
Relevant parameters (described in ''PSTN Parameters'' on page 311):

ISDNRxOverlap_x
