BLF Settings causing our phones to Lockup

[henry_jtek]

Hi all,

After enabling a custom speed dial on one of the BLF settings of our Polycom IP560 (namely BLF Setting 3), our phones lockup every single night and we have to power-cycle them when we come in for the day. When we revert our changes, the phones experience no issues at all. I found an older thread complaining about this but it was locked without a resolution so here I am, wondering if people are still having this problem and if there is a resolution for it yet.

Running v15.5 .. Polycom Firmware 4

Thank you.
henry
