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

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..

Never Use Momentum Telecom

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.

Bye-Bye Mitel - Hello G12!
5
So far we are delighted!!
Ratings Breakdown
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.
