Voice was used in my old comapny and I thought it worked well with how we were situated. Our team were reliant on hot desking and we all had our own Voice logins which made it easy to access any phone and use it as if it were our normal desk.

We introduced the Openscape solution for Corporate VOIP and (partially) presence awareness. Many functionalities have not been enabled as not stable. For example chat and messaging, desktop sharing solutions. I was not primarily involved in the selection of the vendor and in the first trial, but I took part in the rollout and user testing phase. I had experience with other VOIP solutions and I found the solution adopted not good in general for voice quality and portfolio of functionalities offered.
