Mitel Networks 6873I SIP PHONE 50006790

I set one of these up for one of our remote offices the other day. I didn't buy it, so I can't complain too much about the high price, though I've seen similar 7" touchscreen phones from Yealink for quite a bit less.The phone was fairly easy to setup, and works well with our voiSip cloud phone system. I like that is has plenty of programmable virtual buttons. I wonder if it is actually a rebranded Yealink. Hard to say.The person using it says the audio quality is great, and they sounds great to me. I didn't get to put my hands on the phone, since it was remote. But user says it has a high quality feel to it, as much as all the other plastic phones these days.My only gripe is that it seems geared a bit too much towards Mitel phone system, rather than more generalized. Mitel website was a bit hard to find help documents too. If this is your only phone, you probably won't mind. But I work with dozens of different phones, so I'm probably a bit picky.Hope that helps.
