T28P dropping config randomly
Issue: 2 of my Yealink T28 phones randomly drop their config (as in factory reset). This has been happening for over 12 months. This does not happen to any of the other 20 x T28's in use. These 2 phones are located at the reception desk and are part of a call queue.
All the phones are setup as POE. The firmware is v2.71.1.1 (latest 3CX supported). This happened on v11 of 3CX (upgrading to v12.5 made no difference). We have also tried moving the phones to different ports on the POE switch (no difference - still dropped its config).

Setup: 3CX v12.5 system with Yealink T28's working across 3 sites. There is a VPN from each site back to a Data Centre where the 3CX server is located.

Any ideas why this is happening. We had a power out today at this site and the 2 reception phones dropped their config again.
