Issue 13.0
Enhancements
When upgrading to Version 8000 (8.01) or higher software, four IP Terminal Advanced (5111)
licenses are provided. If a system with Version 3000 (3.01 or lower) is upgraded to Version 8000
(8.01) or higher software, the system gains four IP Terminal Advanced (5111) licenses as soon as it is
upgraded.
With Version 9000 or higher software, the NAPT feature is enhanced. Previously, when the DT700
connected to the system via NAPT, the intermediate router/firewall could possibly close the port due to
inactivity for a period of time. The solution for this was to lower the Registration and Subscribe expiry
timers. However, these timers were system wide and would affect all terminals (not just NAPT
terminals), causing an increased network and CPU load. To correct for this issue, Version 9000 or
higher added these timers on a per station basis. This way the NAPT terminals can lower the timers
and not affect all of the Non NAPT terminals. No new licensing is required for this feature; all existing
licenses are still required.
Description
The UNIVERGE SV8100 system supports IP extensions using a variety of multiline terminals. These
telephones have the same look and functionality of typical multiline telephones, but they are connected
to the CCPU via IP rather than by a hardwired connection to a DLC port.
The following DT700 IP multiline telephones (ITL) support IP extensions:
