This thread is crazy. I also found this through google trying to support our users. The fact that this thread alone is 2 years old and this is still being requested shows that your feature request list is a joke.
The first page has been viewed almost 2,500 times. The fact that you have to register, get a confirmation email, and then continue your signup is the reason you dont have more people commenting on this. My corporate email through Office365 rejected your DONOTREPLY@polycom.com address as spam right out, didnt even send it to junk mail. I had to resort to signing up through Gmail to get your registration to process. I would not devote this much time and effort into this if it wasnt for the amount of BS canned responses to these request.
You want numbers? Fine. We have over 150 across multiple offices in the US, Ukrain, and India. We spend the majority of our day doing conference calls. We run Polycom SoundPoint IP 331, 650, 670, 5000, 7000, VX 500 and VX 500. We are not the largest company by any means using your products. But that also means a transition to a different vendor isnt too difficult.
This is a basic feature every phone should have for speed dial. Your users are requesting it. Get it together Polycom. You're disappointing.
