“Solution adopted as a corporate voice communication but I would not recommend it”

3.0
Feb 7, 2019
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.

Performance of OpenScape Voice Across Market Features

OpenScape Voice Likes & Dislikes

Like

This product has a very interesting feature. This is the ability to answer a call on your smartphone and to be able to send this call to your desk phone without hanging up.

Like

We had a solution with a physical phone that replaced the previous PBX system. The integration with the network system was mainly flawless and the physical phone provides a good set of functionality for conferencing and redirecting users

Like

Simple logins and easy procedure to reset pins

Dislike

I have no complaints for the purpose of the tool.

Dislike

Audio Quality is extremely poor if compared e.g. Lync / Skype for business or the old PBX system that we had in place

Dislike

sometimes would randomly reboot my phone but not often

    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.

    Very stable OSV and with basic training the solution becomes administration.

    OpenScape Voice has been deployed as an overlay solution on our existing HiPath 4000 telephony system to provide centralized SIP session management. This simplifies administration, reduces toll costs, and makes it easier to migrate to software-based IP communications.
