Consultative transfers have stopped working - Poly desk phones

[Muffler]

Hi 

We migrated to Zoom Phone in Sept, and have had very few problems - generally very impressed.

However, this last couple of weeks we're having intermittent issues transferring inbound external calls to other users when using our Poly desk phones (VVX601).

They were all on the latest firmware 6.4.1.2361, but suspecting a recent update was to blame I've tried downgrading to 6.4.0.11527 but we're still having the same issue.  Blind transfer works, consultative/warm is hit and miss, when it fails there's a simple message on the sending phone of Transfer Failed.

It appears to all work well on iOS/MacOS/Win10 apps, so I do suspect the Polys are to blame, but it wasn't an issue for the first three months.  No other changes have gone through on setup.

Any help gratefully received.
