Bug Fixes from Prior Versions
This chapter outlines problems that have been fixed from prior
versions of the router software.
Fixes to NauticaRS since Release 4.128R
The following are corrections that have been made to the router
software:
• Corrections to the Call Waiting feature now allow full
operation in areas where this facility is supported.
• It is now possible to download firmware to BRI-ST and
BRI-U ISDN TA modules in a Nautica 4000 using the
Nautica Wizard NDEVLOAD utility.
• If a retry is required for a ‘bandwidth’ ISDN call (additional
data channel), the router code now correctly marks this as a
demand call. Previously, retried calls were always marked as
automatic calls, which could prevent the correct operation of
incoming and outgoing call bumping.
• Incoming voice calls now reliably bump data calls. In the
previous release, the data channel was occasionally not fully
disconnected, resulting in spurious noise at one or both ends
of the voice call.
