The Steakhouse of TelCom - Hidden Gem

5.0 2 years ago

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.

G12 Teams Phone System

4.0 6 months ago

Comments: The team was easy to work with, friendly, and helpful. Despite some confusion, the overall experience was good.

Pros:

Support was easy to work with and helpful. Implementation costs are included in the monthly user license as is all support.

Cons:

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.

Never Use Momentum Telecom

1.0 last year

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

Great product

5.0 2 years ago

Pros:

G12 uses the same Yealink platform that I have used for other phone providers. Moving over to G12 has been seamless. There was no need to learn a new system.

Cons:

There are a few features that are available on my other Yealink platform that are not present with G12. Text to speech voicemail and forwarding the main line from the phone inventory list. Though there is a way to forward the phone number through the software, it requires a few extra steps.

Great phone system

5.0 last year

Pros:

Phone system has excellent performance for standard functionality. No downtime in the past 5 months. Support team is located in the US which makes them easy to work with.

Cons:

Setting up advanced features has been challenging. G12 has been able to accommodate all our requests but it takes a lot of back-and-forth. Configuring some advanced features on extensions is difficult.

Great technology and Good customer service

5.0 last year

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.

G12, Becoming Best in Class

5.0 10 months ago

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.

Excellent support

5.0 7 months ago

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.

Pros:

Excellent call quality. Zero down-time. Outstanding Tech support.

Cons:

None. I can't think of a single thing I don't like about the software.

G12 is good at what it does.

5.0 2 years ago

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.

G12 provides superior customer service

5.0 2 years ago

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.

Not a headache

5.0 2 years ago

Comments: 100% Positive.

Pros:

The implementation was straightforward and the Go Live day was seamless. However, management of incoming calls required a few adjustments after the initial implementation. After staff identified what the gaps were the G12 Team provided options and implemented the changes for us to try. I appreciate the ease of contacting support, their punctual response and clarification of options. They followed up after changes to make sure all worked well.

Cons:

No option to intercom. Like when there is an intruder to alert others.

Great customer service but questionable web interface

4.0 last year

Pros:

Everyone is always happy to help me when I email their support address! They really go above and beyond.

Cons:

The ability to self-service our phone lines in the online Teams connector is lacking. Everyone we set up a new user, we have to email the support email address to have them do everything on the back end. They confirmed with me that it's not possible for us to perform the integration ourselves, so we must rely on their email support team to perform the work instead of being able to completely self-service. It's a good thing their email support is so friendly and helpful!
