Downgrade of 16xx H.323 phones to firmware 1.3.2 from 1.3.3 or 1.3.4B results in duplicate/default MAC and
Serial Number
1603, 1603-I, 1603-I-SW,1608,1608-I, 1616,1616-I
Downgrading 16xx IP Deskphones from firmware version 1.3.3 or 1.3.4.B to 1.3.2 will cause the unique MAC address and Serial
Number as shown on the manufacture label to be converted to default values in the phone firmware (MAC = 00:1B:4F:13:70:08, SN =
123456789012). All phones downgraded from 1.3.3 or 1.3.4.B to 1.3.2 will be affected, resulting in phones having the same MAC
(duplicated) address, and once this happens these phones cannot be recovered in the field. After implementation, phones downgraded
from 1.3.3 or 1.3.4.B to 1.3.2 may not be allowed on the customer network as the phone MAC address will be the default value and be
viewed as a duplicate MAC address in presentation to the network.
Firmware version 1.3.4.D, available since March 2014 does not cause this issue. Avaya recommends that Customers should upgrade
their file server(s) and all 1600 Series phones to 1.3.4.D or newer immediately. As of this PSN update, the current 1600 Series
firmware that is GA is 1.3.5.
Note that once 1600 Series IP Deskphones are upgraded to 1.3.4.D (non-factory image), they can be downgraded to earlier
firmware loads without causing the duplicate MAC / Serial Number issue.
Replace 1.3.2 with 1.3.4D (GA - March 14
th
, 2014) or newer (Firmware 1.3.5 went GA on - April 7
th
, 2014) and upgrade unaffected
phones immediately. Upgrading unaffected phones to one of these releases will prevent the duplicate MAC condition if downgraded
to 1.3.2
Affected 1600 Series IP Deskphones downgraded from 1.3.3 or 1.3.4.B to 1.3.2 resulting in the defaulted/duplicated MAC address
condition cannot be recovered in the field, and should be returned to Avaya under warranty, ideally within the first 90 days under the
DOA process, for a free of charge replacement.
Note: As of May 22
nd
, 2014 all newly manufactured 1600 Series IP Deskphones will be pre-loaded with Firmware version 1.3.4.D and
will prevent downgrade to any version of earlier firmware. Customers will be able to attach these units to their systems seamlessly,
since they will reject any firmware download from the file server. It is still recommended that customers upgrade file server(s) to
have the most current firmware release on them. At the time of publication of this PSN update, it is recommended that customers
upgrade their file server(s) and all 1600 Series phones to 1.3.5, available on the Avaya Support site, at their earliest opportunity.
Workaround or alternative remediation
None – once the phone is in this condition it cannot be recovered in the field.
Do Not plug phones into a network serving 16XX software version 1.3 Maintenance Release 2 (1.3.2) or older. Connecting phones
with 1.3.3 from the factory or phones in the field previously upgraded to 1.3 Maintenance Release 4B (1.3.4B) to a 1.3 Maintenance
Release 2 (1.3.2) will cause the phone to downgrade and get into the default/duplicate MAC condition.
