v5.4.1 and later.
NOTES:
1. As of VOS 5.4.1 and above, it is mandatory to upgrade the firmware on Cisco 7912 /
7905 / ATA-186 to the recommended versions. Otherwise, calls will not complete
correctly.
2. Cisco 7960 / 7940 running the v6.0 firmware is still compatible with VOS 5.4.1 and
above, if you are not using the Flexible SIP Routing's Transparent mode functionality. If
you are using Transparent mode, it is mandatory to upgrade to the 7.3 firmware on
these phones.

VLAN Configuration (4300 Series)
1. Upon enabling VLANs, only LAN Port 4 will be added to the default VLAN. If your
browser PC is connected to a different port you will lose access to the GUI
(until moving to Port 4).
2. Upon enabling VLANs, The default VLAN’s IP address will become 192.168.1.1
(regardless of the LAN IP address prior to enabling VLANs). If your LAN and browser
had been reconfigured to a different subnet you will lose access to
the GUI (until changing to 192.168.1.x).
3. The VoIP ALG page must be reconfigured to associate the ALG with an appropriate
VLAN. Prior to this the ALG will keep restarting.
4. The DHCP Server page must be configured, it does not default to the values used
prior to VLANs
5. Upon deleting a VLAN the DHCP Server must be re-enabled for the remaining VLANs.
•
LAN link up/down SNMP traps for 4200 and 4300 are supported for LAN port 1 only.
•
Dial-plan download limitation with multiple levels of cascaded EPs and EMs. Dial-plan
download is a Survivability feature where, using Broadsoft switches, the V
2
IU will
automatically download the subscriber dial-plan when a phone registers with the softswitch.
This dial-plan is then used during Local survivability mode. This download feature will only
work for the “WAN-most” EM in a cascade of EPs and EMs.
•
It is not possible to manually set an MTU size on the 4200 and 4300 platforms.
•
Windows Messenger support is not available.
•
The web server will log a successful client request/response only when the source IP
address changes from the prior request. This means two requests from the same PC, even if
separated significantly in time, will only have the first request logged. Similarly, requests
from alternating PCs can result in extraneous syslog messages.
Upgrade Instructions
This version of software is available on the Polycom Support FTP site: ftp.support.polycom.com
It is recommended you reboot the V
2
IU appliance prior to doing the upgrade. This is to make sure
there is enough dynamic memory available to handle the upgrade process.
When you update your software telephone services will be unavailable for several minutes. It is
therefore advised that upgrades be performed during a maintenance window when telephone traffic
can be interrupted.
