Grandstream UCM series IP PBXs vs. Zisson Interact

For small businesses (or a school in our case), the Grandstream UCM series IP PBXs system is super impressive as far as what features it offers as well as it's price. It's very simple to deploy and manage allowing one person to get it up and running and then forget about it as it just works. Grandstream offers a lot of PBX control and the product is very scalable as your needs grow. Sound and picture quality is superb as is the reliability of the system. Ours runs 24/7 with no issues. For larger businesses that have 1000's of users, the UCM PBX systems might not be the right fit. However, the largest model can handle 3000 users and 450 phone calls which should be sufficient for most companies I would think!

• The GDS software is built on old technology and somewhat limited in my opinion
• Centralized management of GDS devices has limited functionality in my opinion.
• Grandstream firmware updates aren't very frequent.

We are very happy with our UCB 6308 pair. We have some issues that we would like to see improved, but the UCM 6308 does more than cover the main functionality it is intended for and has given us the needed solution for our remote workers.

Although we are very happy with our pair of UCM 6308, we still think there are some things that can be improved to make this a prefect product! Have mentioned the main points we think that should be improved on other parts of the review.

Grandstream almost always have a first response on any ticket within 24 hours, which is impressive. They do care to listen about customer problems and needs and are open suggestions / feature reuests, as long as there is a potential for the suggested change to benefit a big enough number of customers.

The implementation was concluded very fast, with minimal downtime.

We were considering a solution from Alcatel at first. Very stable implementation for sure, as there are no frequent updates and no new features. Also no conferencing solution was included. A separate solution was offered for extra cost. So the choice was between a very stable PBX which would be pretty much unchanged for ever and a dynamic solution that would constantly grow. Without any doubt we opted for the ever growing / changing solution, knowing this would cost us in minor problems / instabilities. We did NOT regret this decision. So having opted for a growing and constantly developed solution we also look into the solution provided by Yeastar. By comparing the 2 solutions it was obvious that the Grandstream UCM 6308 was the best solution for us.
