We’re Committed to Better Voice Solutions

Unsurpassed Professional Support

I'm a CIO and a new customer of Commio. We had a major issue with migrating our numbers from another business to Commio. Basically, the current partner executed the transfer days ahead of the agreed-upon schedule, not ideal. After many many hours of trying to work with the current vendor to restore our numbers unsuccessfully, our team reached Katie Reddick in your support team. It was after hours and on the weekend but Katie acknowledged our situation, leveraged her connections at Inteliquent, and helped complete our number port which saved us from catastrophic revenue and reputational loss. From my perspective, Katie's dedication confirms that we partnered with the right business and I wanted to let you know personally how much we appreciated her help.

Omnichannel Communications Made Easy

Commio's text messaging capability is easy to use and implement into our existing workflows. Very happy with results. Their platform is robust, powerful, and easy to use. My favorite thing is the ability for a front-end user–non-admin, non-techie–to trace a problem call start to finish and fix it.

Highly Recommended

Now that they've combined their inbound and outbound portals and integrated text messaging support from teli, I like them even more. The setup is easy to use, and the documentation is very complete. The support staff is always great when you do need some help.

Helpful & Knowledgeable

The telecom landscape is changing right now. However, they constantly keep their customers updated with what is going on and what is coming in the future. Tech support has been very easy to work with and has helped me with problems even on my end. Just because they saw it was "not their problem" did not stop them from helping. Everyone else was great to work with as well and was very helpful.

Text Messaging Solution

They have very deep understanding of the new 10DLC/A2P texting regulations and they have been a great advocate for us in the whole process. The service is very reliable, with good management tools. Any problems or questions we have are quickly resolved by their support team. Our Account Manager Pete Sweeney is a great advocate for us whenever we need a little extra assistance beyond the scope of a support team.

Better Voice & Great Support

We have had bad experiences in the past with other companies that were more feature-rich but failed the first time they were DDoSed or failed when a data center had issues. Commio is very strong when it comes to the reliability of their services, clear communication on issues and rapid response when it comes to dealing with problems.

Great Support & Portal

We initially went with Commio because of their prices. However, we've found that not only is their cost incredible, but also their service. Every ticket I've ever created gets assigned to an engineer quickly and the only time I've struggled to get a resolution is when the issue is on some carrier who refuses to do any deep dives. Their portal is also easy to understand and manage. So easy that I've been able to train various other employees on how to use it, and in extreme cases been able to simply talk someone through using it without even having it in front of me.

Better API Platform

The interface of the site Commio.io is the easiest by far on all the providers that I have been to... I on average use six providers and my go-to is Commio as the first option always. It's easy and it just works.

Reduce Twilio Costs

The best part from Commio, when integrated with Twilio in our case, is that it intelligently switches outbound phone providers depending on the destination we call. It doesn't seem like much to save at first, but seeing it in a cumulative view is a significant cost savings over Twilio.

Inbound & Outbound Calling

The portal allows me to purchase numbers, control my inbound and outbound call routing. I utilize Commio for outbound dialing on some equipment, and backup dialing on other equipment. I can configure test environments and route traffic instantly to my environments. I also love the control to change the outbound carrier I am using, especially if we are troubleshooting carrier issues. Support has been great too!

Scale Twilio & Save

We’re now completing calls using Commio at an average savings of 46% over Twilio’s rates. I set up a test account, created a unique ID and token, and made one small change to our existing Twilio code. Easy. I couldn’t believe how easy and inexpensive it was to add Commio to take Twilio’s voice capabilities to the next level.

Reliable & Easy to Work With

The Commio team is easy to work with and reliable. Quick to respond to issues. And they're professionals. They do well in phone number porting, and stay on top of it by not letting port orders sit and stagnate. The use of their API for other services like text messaging, LRN lookup, CNAM lookup, have all been very useful. They're a perfect partner.

High-Quality Service

The level of granular flexibility for daily and cost-per-minute termination calls has saved us many thousands of dollars over the years. The reliability of the service and the features made available via Commio.io or direct from live support staff makes providing VoIP services very manageable. Great service.

You Negotiate, We Save

You took 50% off our bill. You guys negotiate with carriers every day. You give me the ability to pick and choose who’s upstream, so I always get the best pricing, flexibility for routing, and redundancy. I don’t need multiple carriers to provide failover, because with Commio it’s built-in. Thank you.

Better Toll-Free Prices & Support

I was having reliability issues where I was routing my inbound and outbound calls before. Commio helped me solve that, and also allowed me to lower my costs for handling toll-free numbers for my clients. It's a tie between their prices, transparency and customer service. Their customer service has been phenomenal. Starting with the sales team and ending with their technical support, I don't know if I've had a better experience with a company in a long while.

Scale Twilio & Save

We're saving 60% on our calls, and saved thousands over Twilio and Plivo's upgrade fees to add capacity. We use Twilio and Plivo through their full API integrations and discovered that they’re very expensive to scale. Convenient, but expensive. That's when we found you. We needed more upstreams and we didn’t want to write another switch or set up another API in full. Your competitive pricing has worked out very well.

Unlimited Call Flexibility & Routing

Commio is the best voice provider I've used. Being able to send calls over multiple routes and dozens of carriers is the best bang for the buck. If a carrier is having issues you can simply block it and then continue throughout your day. Updating carriers takes about five minutes and it works perfectly. Being able to limit how much you spend on each call and how you manage routes is extremely easy. They also have great customer service if you have any issues.

Fraud Protection

The limits and fraud protection that Commio provides is top-notch. They alert us and shut down fraud almost immediately when it happens thus saving us thousands in fraud.

Fraud Protection Built-In

Commio has built-in account protections to lower your VoIP fraud exposure threshold. They’re a huge part of our fraud prevention policies. It's going to happen, but what matters is how quickly you can respond and if your automation shuts it down before it gets out of hand.

Save on Long Distance

I had to reduce my costs for long-distance termination... Commio was the solution. We're saving 48% over our original carrier. The idea of being able to pick carriers and set my prices of what I’m willing to pay across discrete carrier sets was key. Now I can focus on other parts of my business and don’t have to think about our calls getting completed at the best price. It just works.

Disaster Recovery in Action

We had 2 major outages with Level 3 this weekend totaling 20 hours and 9 minutes of downtime. If we had not been able to provision the 175 alternate phone numbers for our major clients as quickly as we did, we would have been completely dead in the water. Pass this on to your support and engineering departments for me!

Phone Number Issues Solved

After I signed up I transferred all of my phone numbers (DIDs) to them. This works very well. I don't have my DID issues anymore as in the previous cases. Their customer service is the best of all VOIP service providers that I am aware of. They not only have a great ticket system but also telephone support as well. This is quite rare in VOIP companies. And our rates are excellent for inbound and outbound calling. Commio is reliable, and gives me tools I couldn't get anywhere else to customize our routing. Excellent.

Better SIP Trunking

We have better provisioning tools and capabilities to maintain our trunks and telephony, plus great customer service. Commio is super-duper easy to use. It's clean SIP trunking with a ton of redundancy built right in.

Commio Solves Telephony Challenges

Our clients are solving service issues by having the flexibility to leverage many different providers through just one service and interface. It's quite powerful having the ability to switch away from a provider having acute issues is critical to a business that cannot afford any telephony service issues. Hard to put a price on customer satisfaction and perception.

Enterprise VoIP Solution

We use Commio for all of our communication needs... We’re saving more than 80%. That’s a massive cost reduction for any small company like ours. Commio addresses all of our carrier pain points. We have a lot more flexibility and control and we just love it.

Reputable Brand & Support

Commio is a reputable brand that stands with its product to give excellent support. They have helped with the implementation of their platform with me and my team. Striving to resolve issues I had previously had each time made the experience that much better and more confident in the knowledge they were and are a company to worked with.

Redundancy Built-In

With Commio you’re always in control of your calls, not the other way around. I switched mainly to have an auto-failover in case our main routing goes down. Their platform is easy-to-use and straight-forward, and we’re saving money on our inbound and outbound calls, too.

Great Canadian Routes

The fact that they have a presence in Canada has opened up a whole new market for our company. Plus, their dashboard allows me to mingle U.S. and Canadian phone numbers on the same request!

No More Call Completion Issues

We used to have continuous trouble with completing calls with other carriers. But when we routed to Commio they solved our issues. I love the ease of use of setting up profiles and route blocks. Now our calls get through, and I have total control. Amazing.

A Pleasure to Work With

Commio's rates are great, especially for international termination. They saved me money on my outbound calls on every route. If you're considering working with them, go for it.

Superb Service

\Since I started my service with Commio everything was a breeze. Starting with API connectivity for my platform to the customer service I have received, was exceptional. Versatile, great rates, and superb customer service.

Fast, Flexible Call Routing

I love the ease-of-use and control I get for inbound and outbound voice from Commio. I can add or remove numbers and control where they are routed. No need to make a call and wait for a change to be made. I'm in control.

SIP Services

They won our business fair and square. Commio provides all our SIP services, which is what our business resells. Excellent support, highly reliable service, with tons of carriers in route.

Always Improving

Great automation, fraud protection, customer service, and competitive prices. The management will work with you to resolve issues quickly. We have other suppliers that will not be flexible. Also their analytical tools are very relevant and always improving.

5-Star Service

We have always gotten 5-star service from Commio, and they have some of the best intelligent call routing (LCR) rates.

Easy & Flexible Cloud Voice

The Commio platform is robust, powerful, and fairly easy to use. Favorite thing is the ability for a front-end user (non-admin, non-techie) to trace a problem call from start to finish and identify the problem. Second favorite is the ability to switch inbound toll-free routes dynamically if there are any carrier issues. That means ZERO downtime. Text messaging capability is easy to use and implement into our existing workflow. Happy with results.

Financial Services Telecom Solution

We were tired of the old ways of telecom, and Commio delivers a fresh take on the space. We are able to get support for our product in minutes, rather than days. You get to have a relationship with your reps, you aren't just another number on a spreadsheet. Their interface on Commio.io is clean and user-friendly, but also gives smart control of your call routing. Commio solved our need for telecom delivery to our on-prem PBX. Only downside is that we didn't switch telecoms sooner.

Contact Center Solution

We provide a SaaS contact center solution for clients. High availability is an absolute requirement and Commio has delivered that. Had FAS issues with some other carriers. Absolutely none with Commio. Problem solved. Best quality routing for contact centers without crazy rate variation. Other carriers there is a choice between quality and least cost routing. Commio is quality with very good intelligent call routing. They deliver good rates without sacrificing quality or using gray routes.

Great Voice Provider

The combined Commio.io portal is more streamlined and on par with other carriers. But even before that Commio was one of my favorite carriers to work with both on the phone number ordering and porting side as well as support when we need to diagnose a customer call report. We get alerts on suspicious activity and a responsive team to work with. I believe Commio is the only provider we work with that we can actually go into the portal and find a full SIP debug on a call or call attempt and follow the segments through to see deep into which carriers were involved and which connections.

Connect Repairmen to Customers

Many of our customers (ServiceTitan story) are in more rural areas where one route wasn’t getting calls to their premise. We handle 20 million minutes of outbound calling each month, and we were using static dial plans. What we needed was a broader set of carriers with the flexibility to set up custom routing to increase call quality, enable intelligent call routing to save money, and install route blocks to take problem carriers out of route. That's where Commio comes in.

Soft Switch Developer

A big part of IPiFony's service mix has always been Commio for a lot of different reasons. The big ones are the ability to choose from your 40 carriers. We use them in every routing setup, and then being able to develop intelligent cost routing profiles using specific carriers with specific users is key. We can use the carrier who’s going to have the lowest price per minute.

Save 50% on Your Twilio Billio

We’re saving 50% per call in voice costs. Commio is a good option, providing a quick and direct way to take what we already built in Twilio and create carrier-grade pricing and scaling options with their add-on.

Origination & Termination Solution

These guys are awesome, I know most of the staff on a first-name basis. They will help you with anything they can, and their service is literally top-notch, especially for their origination and termination rates.

The Q is for Quick Service

Commio is our primary telephone service provider, and it's good enough to resell their service to our customers. Highly reliable and low cost, it doesn't get any better. Easy to use, great pricing, and excellent support. The staff isn't afraid to share technical details, and are transparent about their processes.

Non-Pushy VoIP Provider

I wanted to use rates from several different carriers without having separate accounts. With Commio, I get access to their routes and rates without signing into 12 different accounts and downloading 12 different rate decks. Plus they aren't pushy, which is a big plus in starting a relationship. It just works, and saves us money every month. Perfection.

Great Prices & Support

Commio provides cost savings compared to other providers. Origination prices are about as good as you will find. Unlike other providers in the same category, Commio won’t charge you extra to open tickets or obtain support. Termination functionality allows you to set your preferred carriers and to use intelligent call routing (LCR).

Healthcare VoIP Success

We aggregate services from SMBs, mainly in the medical professions. The ability to interface with their support staff has helped greatly in our porting process to get clients off of absurdly expensive and in some cases unreliable providers and provide reliable, balanced access services to our customers in all facets of the VoIP telecommunications world.

Custom Route Blocking

We use them for intelligent call routing (LCR) and for our inbound numbers. Their custom route blocks that you can enable on their web interface bring them to god-tier since we don’t have to make a ticket with them or the ULC to resolve bad routes. Their support is super-responsive as well. Highly recommended.

Free SIP trunk for Asterisk alternatives don’t make the cut when it comes to the reliability of your communications. Commio does.
