Yealink VPN doesn't automatically reconnect?

I’ve got a bunch of Yealink T26P handsets distributed for testing and am having one last issue.
My remote units connect to our gateway via OpenVPN. The connection works fine, but if/when the VPN disconnects for any reason, it doesn’t seem to make any attempt to reconnect until you force a reboot.

Anyone know of a way to force the VPN to test itself for connectivity and reconnect automatically?

Still no solution. Anyone make any progress on this?!

I suggest contacting Yealink.
