1616-I duplicate MAC address

[semihbayraktar]

Hi all,

Other registered 1616 IP phones are running same FW (ha1616ua1_3100.bin) version with the brand new phones. When this problem appeared, I applied the version 1.3.5 and/or 1.3.6
referring the PSN #PSN004134u. But, it didn’t help we are still getting the same MAC address from all new added phones not for the already registered phoned.

thanks in advance

Here's a quote that might be relevant to the issue you're having, it seems that firmware updates on already affected phones will not fix the issue.

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.
