Momentum Reviews for Indian Users

The Steakhouse of TelCom - Hidden Gem
Comments: 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.
Excellent support
Comments: It is overall very easy to use and if there are issues, you submit a ticket or call and you are able to get the issues or answers to questions quickly. If it is a process, then you are kept in the loop of who is working on it and what stage the ticket is in.
Pros:
User Friendly and the feature of seeing names of those calling in and if there isn't a name associated then over 90% of the time there is a number associated that I can research where it came from.
Cons:
I just wish that we could delete VM from our email and that it would delete from the desktop phone as well. We work remotely part of the time and so I come into the office with a lot of emails to check.
Never Use Momentum Telecom
Comments: 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:
Not much. I trust that as customers start submitting reviews, the firm will go out of business.
Cons:
Poor customer service, poor communication, unethical, unprofessional
G12, Becoming Best in Class
Comments: G12 does an excellent job at retaining customers. What I appreciate is their willingness to work with me in setting up SIP services on an older PBX. They have a keen sense of this technology which I belileve gives them an edge.
Pros:
G12's process from initial inquiry, to creating scope of work, implentation, and follow up is exceptional. G12 has experienced engineers which I have utilized to turn up services as well as trouble shoot issues that come up.
Cons:
So far I can't say that I have any Cons to report. G12 is a very good company. Their pricing is very amenable compared to the ILEC and other CLECs.
Great technology and Good customer service
Comments: In my experience, G12 Communications has proven itself to be a remarkable platform. Its integration of Microsoft Teams with VOIP has transformed our communication processes and heightened productivity within our team.G12 Communications not only offers technologically advanced solutions, but also excels in the sphere of customer support. As a veteran, I have high standards for professionalism and efficiency, and I can attest that G12's customer service meets these standards effortlessly. Their team is always responsive, kind, and ready to assist, which speaks volumes about their commitment to customer satisfaction.What stood out to me was a meeting with their [sensitive content hidden], where the emphasis on professionalism in staff training was highlighted. This focus is evident in their exceptional service - in the few instances where I needed to submit a support ticket, each issue was addressed and resolved in a timely manner.
Pros:
I am absolutely thrilled with my experience using G12 Communications. The aspect I admire the most is how effortlessly it integrates Microsoft Teams with VOIP, creating a unified communication platform that is both efficient and effective. This seamless integration has greatly enhanced our team's ability to collaborate and communicate, which has in turn boosted our productivity.
Cons:
However, like any innovative solution, there's always room for improvement. One area that falls a bit short of expectations is their SMS functionality. Currently, it doesn't operate as fluidly as I would like, leading to it being underutilized by our staff. Nevertheless, I have been informed that their dedicated team of engineers is working on enhancing this feature, and I am eagerly awaiting the upgraded version.
Great customer service
Pros:
When there is an issue, communication with team to find a solution is very quick
Cons:
No big issues have been left unresolved. Sometimes the issue is found to be internal, but G12 is still willing to assist.
G12 provides excellent VOIP and support
Comments: Very good experience. Using their services for several years now.
Pros:
Ease of use and flexibility for my small business
Cons:
The user portal a bit confusing for people on my team
Took too long to remediate
Comments: Overall, good; right now, I'm upset that it took 4-5 calls to get assistance and resolution.
Pros:
Historically, the service response, and call quality.
Cons:
The service response, and lack of speed to get this issue resolved.
Would not recommend.
Comments: Horrible, this has been the worst phone system I've ever used. The customer service and tech support did nothing to help when we showed them the issues we were having and how it was impacting our business, they told us to get over it.
Pros:
Nothing! I was super excited to use the program, but it was a complete let down. Patients could not call in because G12 showed our number as not in service. Call would disconnect if you tried to transfer them, and the texting stopped working all together a month into the program. The support team was not helpful and did not fix any problem when we brought them up.
Cons:
Everything, the system stopped working with in 4 months and customer service did not help with any issues we were having. When we told them it was negatively impacting our business, we were told they could do anything to help. We lost clients because we did not have a reliable phone system.
Big Upgrade and Great Service
Pros:
The phones we have from G12 have lots of features, and customer service is great when I've needed help.
Cons:
Call transfers can be a little tricky sometimes. The speed dial buttons are annoying to program when you have lots of users.
G12 is easy to set up and use - good for IT and for the user!
Comments: Frictionless
Pros:
Great web portal for admin and for users. Good quality phones.Solid call qualityGreat softphone feature, for cases where the physical phone is not present.
Cons:
Don't really have anything I don't like. Especially when comparing to the alternatives
Perfect for our company
Comments: Overall it has been a positive influence for us, I would suggest it over Comcast anyday!
Pros:
G12 has been a very user friendly system for our company. The support has been excellent also.
Cons:
It was a little confusing on the phone tree.
Highly recommend
Pros:
The constant strive to fix the issue and constant contact.
Cons:
nothing, I haven't had any issue with G12.
Best customer support!
Comments: Super friendly, prompt and ready to help!
Pros:
I am just an employee and user of G12 but every time I submit a ticket or ask for help they are quick to respond, support and fix any issues I may have.
Cons:
Nothing! Products are great and customer service is even better
Best Customer Service
Pros:
Very easy to use and understand if there is an issue there easy to get a hold of
Cons:
I've got nothing negative to say about this software
G12 provides superior customer service
Comments: Love working with the G12 team!
Pros:
While the G12 system supports our needs, the main reason we stay with them is their customer service team. They respond quickly, stick with the issue until it is resolved and are excellent when there is an emergency and I need a quick response.
Cons:
I would prefer that the extension be tied to the physical location as opposed to the phone console but it is not a huge hinderance.
Alternatives Considered:
G-12 is a great phone system for businesses
Comments: Absolutely great! Everyone in our office has been VERY pleased with the G-12 phone system!
Pros:
The flexibility of the call routing feature to adapt to the ever-changing variables of our office.
Cons:
Wish there was an easier way to connect a long-range wireless headset to the system. We experimented with a few and did not have the best luck. Wish G-12 offered these devices with the corresponding support.
Great Communication Tool
Comments: The G12 team were friendly, knowledgeable, helpful, and courteous. A great team to work with that assisted through the process of getting everything set up.
Pros:
For our clinic, it's important to be able to have as many details about our callers at our fingertips quickly. With G12 phone services we have the patients' name or phone number on the caller ID which allows us to look up their account as we're picking up the phone. This helps productivity as well as increases the patients' experience. It's also very helpful to receive an email notification when a voicemail is received that allows you to listen to the message from anywhere at any time as long as you have access to your email. And when that's not available, their mobile app that allows you to listen to your voicemails is so convenient.
Cons:
The service required the purchase of new phones. It's important to factor in time for this process. The time it took to have the phone shipped, delivered, and installed was longer than desired.
G12 is good at what it does.
Comments: Good.
Pros:
It works- smoothly and mostly glitch-free. We have only had one major issue, and it was resolved within a day.
Cons:
The major issue we had was when the system decided to, without any warning, shuffle which phones were linked to what number. It was very strange there, and everyone was panicking a bit.
Small Law Firm Switching from PBX to VOIP
Comments: The firm was very responsive during a hectic setup period arising from a move of our office location and a switch from a T-1 PBX to VOIP. They did a good job at a handling a pretty complex number porting project.
Pros:
Good customer support during the deployment process
Cons:
The user interface takes some getting used to.
G12 Teams Calling
Comments: Good experience and happy with the end product/services.
Pros:
Easy transition from hardware to Teams calling and ported numbers over worked well.
Cons:
There were challenges in getting all the numbers assigned to the right people during implementation that caused a lot of confusion
G12 SIP System.
Pros:
The phone system is easy to use and is very flexible. The support is very good and responsive.
Cons:
I have a "call forward" feature on one button, but it doesn't seem to work at all times I need it to.
Good Value For Growing Businesses
Comments: Good. One of the very best support organizations I've ever interacted with, anywhere.
Pros:
G12 has the ability to scale seamlessly with a small business. As we grow as a business and our needs change, G12 usually has a solution or reasonable workaround. They back it up with World-class support.
Cons:
I would employ a more mobile-first strategy.
Awesome platform
Comments: G12 has been awesome to work with, from the initial sales call, implementing the new system and after support. I highly recommend G12.
Pros:
Everything works perfectly. The system has all the features we need and more.
Cons:
No cons, everything is perfect and works as it should.
Overall Excellent Product
Comments: Anytime we have an issue it seems to be taken care of quickly.
Pros:
The ability to work remotely without losing calls
Cons:
Address book, ext list availability would be nicer to have
