IP Phones failing after 17.1.1 upgrade from 17.0, thoughts?

Hello,

We upgraded an XG 230 HA pair from 17.0 to 17.1.1 last night.

Today all of the FUZE ip phones are failing on a regular basis. We saw the same behavior when we upgraded from 17.0 to 17.0.5.

I was hoping the issue had been fixed in 17.1.1 but it hasn't. We ended up reverting to 17.0 when we ran into the issue with 17.0.5.

I am hoping I can stay with 17.1.1 this time.

It seems like a connection track or UDP timeout issue to me. Current UDP timeout is 370 but the phones are cycling around every 18-20 minutes. I don't know what process in 17.1.1 would happen every 18 minutes though that would kick out all of the phones. 

Any thoughts?

 

Thanks,

Brent
