About Momentum

Alteva is a provider of telecommunications services that offers a cloud-based business phone system called Alteva Hosted VoIP. Alteva also offers SIP trunking (a service that connects calls between VoIP systems and the traditional phone network) for organizations that want a single-vendor communications system.

Since Alteva also provides Internet service, it can offer customers a fully managed connection to its SIP trunking service and hosted PBX applications. T1, fiber and MPLS connections are available from Alteva.

Alteva Hosted VoIP offers a number of standard PBX features, such as call forwarding and call transferring. Users can receive voicemails as emails and have calls forwarded to mobile devices when they’re out of the office. Employees can manage call routing settings via a Web portal, and a Web-based call manager is also available for transferring calls with a Web browser.

Alteva Mobility is a client that extends unified communications features to desktops and smartphones. Users can access communications services and display a single identity from all of their devices.

    The Steakhouse of TelCom - Hidden Gem

    5

    Our previous provider COULD NOT keep up with our UCaaS growth potential. Their system was OLD and antiquated. They wanted us to keep the partnership and move us to the "New" cloud PBX. They weren't there yet. There wasn't any redundancy, no flexibility to manage users quickly and NO e911 services. We're NOT a beta company. We NEEDED a solid UCaaS system which was cloud based that we could use for administration and have e911 capability. We seriously vetted through 5 company's and after checking all the boxes they all talked and seemed the same. I was actually numb from hearing the same thing over and over again. I was introduced to G-12 actually as a final resource. "YOU MUST Hear this guy [SENSITIVE CONTENT] tell their story of G-12 and what they have." Got on a conference call and let [SENSITIVE CONTENT] start his Demo and I asked him specifically. "[SENSITIVE CONTENT], why should I go with G-12 over all the others that I've had demo's with?". As soon as I saw the conviction in his face and him talk about how his team was i.e. provisioning, porting, support. This dude was passionate. I gave him top seat in my vetting process. I asked him to prove it. I was quickly introduced to his teams and listening to each one of them through out this process solidified my decision. With their provisioning team, porting team and support I'm now 1350+ users, 1200+ UC phones, 30+ Softphones, Teams Connections. I got EXACTLY what I asked [SENSITIVE CONTENT] team for NO FLUFF..

    Pros:
    As a TelCom engineer and system administrator, it's EXTREMLY important to have a plan. That plan revolves around my office staff's needs and the flexibility of the system to help make business decisions which makes my team and callers experience the best that can be. G-12 admin portal that sync's to Cloud PBX makes it SO SIMPLE to view, plan and strategize for growth and visualize call routing, make adjustments on the fly and most importantly have the provisioning team give me guidance and a REAL support and engineering team to be there when needed.
    Cons:
    We as Tech people wish that we had an out of the box, turn-key solution that works 100% to our favor. This is a GREAT wish list for all IT teams. There are a couple of items that I wish I could change, but these items are so insignificant and do not hinder performance to any degree. More of a cosmetic thing. For the sake of this portion of my review, I'll note - The admin portal is also cloud based. The admin panel has MANY pages and options to choose from like Users, Auto Attendants, Queues, Inventory, etc. A few of these pages I wish that we could change sorting features. I know, it's petty but sometimes, this gets annoying. Other than that, I don't have access to softphone users and management area of that just yet. It's coming but not just there yet.

    Never Use Momentum Telecom

    1

    On 4/18, my dad emailed Momentum Telecom that his firm was closing. He attempted to shut down the service. He is 73 years old. Momentum would not help.He sent formal notice via email on 5/14 that I was authorized. I called [sensitive content hidden] on 5/14. No one answered. I sent an email and called on 5/15. No one answered. I called the main line for Momentum. My father authorized me on the phone. They said only my account manager, [sensitive content hidden] , could help. They said she would call. No one called.After two days, I called [sensitive content hidden] and the main line again on 5/17. I made a formal complaint. I was transferred to someone who assured me someone would call. No one called. On 5/19, [sensitive content hidden] emailed that we owed an early termination fee of 3,143.87. I called and asked for an explanation of the bill. They told me someone would call. No one called.On Monday, 5/22, [sensitive content hidden] emailed that I was not authorized on the account. Dad reiterated that I was authorized. We asked for the original contract. [sensitive content hidden] emailed it to us. The contract was signed by a former employee who didn't have authorization to enter the firm into financial contracts.On 5/23, [sensitive content hidden] said she had had a full schedule, clarifying why she didn’t call. Then stated she could not answer questions about the final bill until 7/1.They called on 5/26. Dad promptly handed the phone to me. I asked why we were being charged 3200 when our monthly bill was 160. They were confused and said we owed them 1600 without explaining why.

    Pros:
    Everything!! Having used and been the administrator for a Mitel system - G12 is like turning in your old beater car that consistently would breakdown for a slick new ride! Easy to use, program, train, so many options for call handling. As the administrator - it's easy to assist employees with personalizing their set-up and assist with options. Fast and not complicated at all - I am able to bounce in/out of the manager portal in seconds.
    Cons:
    wrap-up mode - needs the ability to know when someone is in wrap-up mode. This is for those that are not in the call center group. There is no indicator that shows the person is busy when in wrap-up mode - just on the phone (red) or available (green). Maybe a nice blue color would indicate the person is in wrap-up mode.

    Reasons for choosing Momentum

    overall - met our needs... we knew what we wanted and they could provide it. Seriously, we really vetted all the companies we looked at and took them to task. G12 hands-down was easy overall. We had such a bad experience with Mitel we knew exactly what we didn't want and what we wanted.

    Reasons for switching to Momentum

    Mitel gave up and sold to RingCentral. We vetted 3 companies including RingCentral and found G12 to meet all our needs - and was by far the best system for all the different scenarios our company requires.

    Setup was confusing. They provide you with an initial Excel workbook and your project manager walks through it with you. The PM is not able to answer all the questions and the workbook doesn't have great instructions.

    Pros:
    G12 was a very easy integration of CloudPBX and our Microsoft Teams integration of voice services. Very easy to handle adds, moves, deletes in management while the end user experience is virtual, so not tied to any location, just available Internet anywhere in the world.
    Cons:
    They do not currently provide IVR services within their platform, so Call Centers users need alternate options.

    Reasons for choosing Momentum

    We have used G12 Communications for many years for SIP trunking services. Our existing relationship make this transition very easy. Also G12 is based in our geographical area and peers on our regional Fiber network provider.
