Grandstream presents the UCM series of IP PBX appliances as powerful yet easy to manage voice, video, data, and mobility communications platform, whichoffer an extensive set of unified communication features in an easy to manage on premise solution with no licensing fees, upgrade fees or costs per features. The Grandstream UCMs range from small and medium business deployments to small and medium enterprise solutions.
Cisco IP Phones allow you to use built-in features as well as additional functionality in combination with other Cisco products (CUCM, CMS, Webex, Expressway).
We have found so many use cases for Cisco IP Phones and have not come across too many situations where they were not well suited, other than being mobile. We have moved to another Cisco Solution for Mobile communications. We have phones all over the place, in offices, in clinical areas, in lobby or public areas, and even in all of our conferencing and meeting spaces.
As a PBX the UCM PBX can be cover the needs of all companies without exception. We think it is really a great and flexible solution that covers all the IP telephone needs a company may have. When we were researching the market to buy our pair of UCM 6308, we had also hoped to use it as a replacement for our Skype for Business installation, so to say to use it as our main solution for video conferencing. After trying to do this for a couple of years we would say that you can use Wave for video conferencing and I personally like it, but it is not well suited for bigger companies for using it as the main video conferencing solution. On the other hand, there are very few PBXs even offering a video conferencing solution and their solutions are not better that the UCM's solution!
So while the 6800 range may not offer slick features, it still provides all the core functionality that businesses have come to expect from their VoIP handsets.
Most of the handsets that make up the 6800 series do come with a greyscale display, which may be disappointing if employees are used to working with color VoIP solutions.
The cluster implementation does not work on all network modes. Would be great if this was improved.
Wave on mobile phones works in a different way than on desktops and this makes it hard to set it up for use on the firewalls, as it requires different and more permissions than the desktop app. For example is one receives an invitation per email on the mobile phone and wants to participate in a Wave meeting as a guest, the still need access to the network ports needed to login the extension (while they only need / want to join the meeting as anonymous users). On the desktop app this is not needed.
There is a limit on the number of 1 device per connection type. We have an extension used in the maintenance department and is shared by 6 users. We were able to install it on 1 PC, 1 Wi-Fi phone and 1 Android shared mobile phone. We would like to install it on a second shared mobile phone, but this is not allowed by the UCM policy. We could use anther extension to do this, but the maintenance department does not want this. They want to accept calls with problem reports only on one extension. Would be great to be able to install the same extension on more than 1 Android devices.
i think it's profitable and a good return on investment as a person who make an architecture based on VOIP with IP phones i really enjoyed the process of configuration of the router , the switch and everything and then when i had to test the communication between two phones I've configured it was a joy. Also it's a good phone to receive and give calls to our clients.
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.
Easy to use Functions are self-explanatory Light Efficient I generally have no complaints about them as they get the job done. Just a few employments on maybe graphics or so otherwise they are really great 👍 no complaints... Maybe it is just because is just a user and doesn't implement them or something.
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.
Cisco IP Phones support have met our business time to resolution, leading us to very low downtime, and allowed us to interact with our customers quicker and better and provide us with an adequate ROI. Cisco support has been within established SLA and the quality of support has been high leading to a high % of first touch resolutions.
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 8800 series phone is lighter and has a better build quality with all except the flagship phones from Yealink, Mitel, and Avaya. The Yealink S59 and Avaya Vantage have a touch screen interface the make them more akin to the old DX650 which is more high-end than the 8800 currently.
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.
I set up the desk for new hires in our group - it is super easy to plug in this phone and have them up and running.
Having the ability to pre-program speed dial numbers ensures that new hires are able to reach help without having to search for a number.
The ability to program ring tones is great, so if we are in the shared space meeting and we hear a phone ring, we know who's phone is ringing - the meeting can go on without everyone leaving to check.
