Gateway-Serial)
Use default service bit

services defined to use
'auto' bit rate
Description
Select to instruct the LifeSize Gateway to attempt to
reconnect video calls as voice calls after a video call has
failed at call setup. The LifeSize Gateway uses the
auto-redial mechanism for outgoing video calls when any of
the ISDN disconnect reasons listed below occur.
When selected, the LifeSize Gateway first tries to redial the
call as a restricted video call at 56 Kbps. If the call fails for
any of the reasons listed below, the LifeSize Gateway tries
to redial the call as a voice call.
When deselected, the call disconnects.
The LifeSize Gateway log indicates both the disconnect
reason and the LifeSize Gateway attempt at redialing.
Note The auto-redial mechanism operates independently
of the downspeeding functionality.
The ISDN disconnect reasons are:
0x12—No user responding.
0x39—Bearer capacity not authorized.
0x3a—Bearer capacity not presently available.
0x3f—Reports a "service or option not available"
event only when no other cause in the "service or
option not available" class applies.
0x4f—Reports a "service or option not
implemented" event only when no other cause in
the "service or option not implemented" class
applies.
0x41—Bearer capability not implemented.
0x45—Requested facility not implemented.
0x58—Incompatible destination.
Choose the default bit rate. When using a service with the bit
rate set to Auto, the LifeSize Gateway uses the default bit
rate if the received bearer rate is not one of the supported bit
rates.
