Before You Upgrade; Please Read Before Upgrading Your Phone - Aastra 9143i Series Release Notes

SIP IP Phone Models 9143i, 9480i, 9480i CT, and 67xxi Series Phones

Before you upgrade

Please read before upgrading your phone

If you have a firmware version on your phone prior to 2.3, please read the following
IMPORTANT information before upgrading the phones:
• LLDP is enabled by default
If LLDP is enabled on your network, the phones may come up with different net-
work settings. For more information about LLDP, see the Aastra SIP IP Phone
Administrator Guide.
• Support for DHCP Options 159 and 160
If the DHCP server supplies Options 159 and 160, the phones will attempt to con-
tact the configuration server given in these options. For more information about
Options 159 and 160, see the Aastra SIP IP Phone Administrator Guide.
• HTTPS validation
If you are using HTTPS and the certificates are not valid or are not signed by Veri-
sign, Thawte, or GeoTrust, the phones fail to download configuration files. For more
information about HTTPS validation, see the Aastra SIP IP Phone Administrator
Guide.
• Watchdog task feature
If the phone detects a failure (for example, a crash), the phone automatically
reboots. For more information about the Watchdog feature, see the Aastra SIP IP
Phone Administrator Guide.
Note:
If you factory default a phone with Release 2.3 and above software, when the phone
reboots, it attempts to connect to rcs.aastra.com. There is no personal information
transmitted from the phone and the phone continues to boot up as normal.
Warning:
Applicable to IP Phone Models 6730i and 6731i only:
The default negotiation setting for the Ethernet ports on the phones is "auto-
negotiation" . If you have changed this default setting to another value (i.e.,
Half Duplex or Full Duplex), you MUST set the negotiation value back to the
default value of "auto-negotiation" before upgrading to Release 2.6. Failure
to do so may cause the phone to fail to connect to the network. In addition,
downgrade will not be possible.
