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 Models 9000i and
6700i Series SIP IP Phones 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 Models 9000i and 6700i Series SIP IP Phones
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 Models 9000i and 6700i Series
SIP IP Phones 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 Models
9000i and 6700i Series SIP IP Phones Administrator Guide.
Note:
The following information applies to all IP phones EXCEPT the 6739i.
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-nego-
tiation”. 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 3.2. Failure to do so may cause the phone
to fail to connect to the network. In addition, downgrade will not be possible.
