Rated 5 out of 5 by Powerful Signal from Works GreatWorks well with our Mitel phones. Now we don't have to use the awkward handset lifter.

Rated 4 out of 5 by Frankybones from Works with OpenStage 40This does work with the OS 40 and is much better than using the lifter. The only reason I only gave it 4 stars is because it is so darn expensive!
