I have yet to mount it, but I am fully confident it will work as intended.
remember to turn the handset latch around for wall mounted mode. (see pictures)
this will prevent the handset from falling off, very nice feature.
Thank you GreenAlienGeek you have saved me hours and like $40.00!
Hopefully we can help others too! :D
EDIT
went to mount this thing… and guess what its really hard to get it to mount when you have to work with a wall…
changed the screw holes to keyholes. now you can mount the bracket and then put it on the wall! – much easier!
The author remixed this model.
I slimmed it up, changed the mounting holes to take flush head type concrete screws,
and added a shoretel115 badge.
