RE: T27G - Fall Back issues - Successive setting [Still an issue]
This issue returned a few days later - highly unusual

Since then have done a lot more testing and diagnosis (however but of the issue is that the system in question is in full production use, in a remote location, so normal range of diagnostics is a little restricted.

As I did before the work, all of this mechanism was tested and tested again, before this was put into production.

Since then, we have implemented a full test replica again in a lab setup. It works perfectly...with both systems online - Phone only registers to the Production PBX. Shutdown the production PBX, and the phone registers to the Backup PBX. Bring the Production back online, within a minute or two, the phone unregisters from the Backup PBX and registers back to the Production system

Have confirmed that the T27G Phones on both the Production system and the Replica that we setup are identical. FIrmwares identical, configurations identical (except for registration details) - using diff against exported configurations.

In case I have not mentioned it, it is using Asterisk based system - same versions.

Now to be fair, this does not look like a Yealink issue entirely, however it is only the Yealink with the failover capability. Anybody seen this issue before???
