VPN phones - IKE version 2

[halj]

Hello guys,

I am using 96xx series phones to connect a VPN concentrator.
Issue is that newer VPN concentrators dont accept IKE version 1 anymore.
The 9608 firmware that I have here is 6.8202 and it has as options just Sha-1 for encryption.

Does anyone knows if there is any other Avaya phone that Accepts IKE version 2?

I have also tried with version 6.85 (96x1-IPT-H323-R6_8_5_02-110720) but unfortunately doesn't work.
