General Call Control Behavior

SIP User's Manual
Table 5-43: E1/T1/J1 Configuration Parameters
Bit-field used to determine several general CC behavior options. To
select the options, click the arrow button, and then for each required
option, select 1 to enable. The default is 0 (i.e., disable).
[2] = data calls with interworking indication use 64 kbps B-
channels (physical only).
[8] REVERSE CHAN ALLOC ALGO = Channel ID allocation
algorithm.
[16] = The gateway clears down the call if it receives a NOTIFY
message specifying 'User-Suspended'. A NOTIFY (User-
Suspended) message is used by some networks (e.g., in Italy or
Denmark) to indicate that the remote user has cleared the call,
especially in the case of a long distance voice call.
[32] CHAN ID 16 ALLOWED = Applies only to ETSI E1 lines
(30B+D). Enables handling the differences between the newer
QSIG standard (ETS 300-172) and other ETSI-based standards
(ETS 300-102 and ETS 300-403) in the conversion of B-channel
ID values into timeslot values:
1) In 'regular ETSI' standards, the timeslot is identical to the B-
channel ID value, and the range for both is 1 to 15 and 17 to 31.
The D-channel is identified as channel-id #16 and carried into the
timeslot #16.
2) In newer QSIG standards, the channel-id range is 1 to 30, but
the timeslot range is still 1 to 15 and 17 to 31. The D-channel is
not identified as channel-id #16, but is still carried into the timeslot
#16.
When this bit is set, the channel ID #16 is considered as a valid B-
channel ID, but timeslot values are converted to reflect the range
1 to 15 and 17 to 31. This is the new QSIG mode of operation.
When this bit is not set (default), the channel_id #16 is not
allowed, as for all ETSI-like standards.
[64] USE T1 PRI = PRI interface type is forced to T1.
[128] USE E1 PRI = PRI interface type is forced to E1.
[256] START WITH B CHAN OOS = B-channels start in the Out-
Of-Service state (OOS).
[512] CHAN ALLOC LOWEST = CC allocates B-channels starting
from the lowest available B-channel id.
[1024] CHAN ALLOC HIGHEST = CC allocates B-channels
starting from the highest available B-channel id.
Note: When using the ini file to configure the gateway to support
several ISDNGeneralCCBehavior features, add the individual feature
values. For example, to support both [16] and [32] features, set
ISDNGeneralCCBehavior = 48 (i.e., 16 + 32).
