0 = Lock the trunk; stops trunk traffic to configure the trunk protocol type
2 = Unlock the trunk (default); enables trunk traffic

hold Re- INVITE) message is received before the timer expires, the call is
renewed. If this timer expires, the call is released.

0 - 2400 =Time to wait in seconds.
Currently applicable only to MFC R2 CAS variants.
ISDN Flexible Behavior Parameters
ISDN protocol is implemented in different Switches / PBXs by different vendors. Several implementations
vary a little from the specification. Therefore, to provide a flexible interface that supports these ISDN
variants, the ISDN behavior parameters are used.
ISDNInCallsBehavior
[Incoming Calls Behavior]
2048
= Sends Channel ID in the first response to an incoming Q.931 Call
Setup message. Otherwise, the Channel ID is sent only if the gateway
requires changing the proposed Channel ID (default).
8192
= Sends Channel ID in a Q.931 Call Proceeding message.
65536 = Includes Progress Indicator (PI=8) in Setup ACK message, if an
empty called number is received in an incoming Setup message. Applicable
to overlap dialing mode. The parameter also directs the gateway to play a
dial tone (for ‘TimeForDialTone ’), until the next called number digits are
received.
262144 = NI-2 second redirect number – Users can select and use (in
INVITE messages) the NI-2 second redirect number, if two redirect numbers
are received in Q.931 Setup for incoming Tel
Æ
IP calls.
To configure the gateway to support several
‘ISDNInCallsBehavior’ features, summarize the individual
feature values. For example to support both ‘2048’ and ‘65536’
features, set ‘ISDNInCallsBehavior = 67584.
