Our Values

To Embrace and Drive Innovation

Embracing and driving innovation means, to us, to look not only to the industry standards when developing our portal and features, but for newer and more innovative solutions which create better experiences for our customers. We strive to set the bar for industry standards.

To Pursue Growth & Learning

As a company we have grown not only in size but also as individuals. We attribute this to our dedication to learning from every mistake, criticism, and success that we have encountered. We will never stop learning and improving and we wouldn't have it any other way.

To Build a Family Spirit

By creating a friendly and caring atmosphere in the office, rewarding loyalty, and promoting a strong work/life balance, we go to great lengths to ensure that as members of this organization, we are not only a team, but actually a family. This synergy is apparent when our customers call in.

To Be Adventurous and Creative

When problems arise, being adventurous and creative often leads to the world's greatest solutions. Although our troubleshooting philosophy is built on proven standardized protocols, our creative culture is built on using our super-complicated portal to solve any difficult problems that can't be done by the book.

To Do More With Less

As an employee-owned company, we will never have the capital and resources of our largest competitors. For us to move mountains, we have to focus purely on what matters the most: customer service. This has kept our customer retention at over 95% since 2008 without contracts!

To Be Passionate & Determined

Every day we wake up we are passionate about making our customers' businesses run more smoothly and effeciently. We are determined to solve any problems we may face throughout the day to provide a truly compromise-free service for every one of our customers.


SoundLine™ Communications, founded in 2008, is a business phone company and cloud phone system innovator based in Woodinville, WA. SoundLine™ provides the best multi-office phone solution for businesses throughout North America by innovating, creating, and personally supporting the most flexible, automated, and simplified cloud phone system. Due to the advanced nature of the technology and services offered, businesses with multiple locations throughout North America and Canada are particularly well suited for our service. We also focus on smaller companies who are looking for the best scalable foundation to expand their operations. SoundLine™’s goal is to be every customer’s final-destination phone company. While there are conniving ways to keep customers in perpetuity, SoundLine™ remains confident and offers only month-to-month services without any binding agreements. We are proud to maintain over 95% customer retention and satisfaction year after year. In 2016, SoundLine™ limited future growth to 3,000 customers with the goal of not expanding operations or the team any further. The driving force was to split future profits between the entire team versus needlessly growing and convoluting the company. Investing in the team has paid off exponentially. We have amazing customer service and have cultivated a family atmosphere within the company as well as with our customers. SoundLine™ is proud to offer a lifetime solution for each team member and every customer.

The features we get with their systems has enabled us to do a better job in staying in touch with our clients immediately. Their system has been a big improvement while lowering our overall communication costs."

~Jim Conway, ASB Seattle

"We couldn't be happier with our decision to purchase SoundLine™'s hosted VoIP service. We received a great deal on hardware, and the team has been extremely attentive to our needs by going to every length to make sure our system is hand-tailored to our rather specific needs. We definitely feel like we're in good hands with SoundLine™."

~Erin Resso, The Stranger

I've used SoundLine™ Commination's service for the last 4 years and am very pleased with their excellent customer service, technology & features advances and the ease of using their phones.

~Michael Roberts, VMS

"The service has been great!!!! Quick responses when we need changes to our account. The call recording feature was something we were missing, now it makes us more efficient and we can see where we need improvement. The addition phone numbers for tracking our marketing is a must have and is very inexpensive. If I could give 10 stars I would!!!!"

~Jason Hunt, Hunt's Plumbing

~Richard Chan, Richard Chan Orthodontics

"As a small business man, I find myself having to occasionally ask favors of my vendors. Never in my 25+ years in business have I come across a company that is so willing to go far beyond my humble, sometimes difficult requests...and each of my requests are always met with a smile from SoundLine™ employees. Barrett, you have something special going on at SoundLine™. Keep do what you're doing! Thank you!! You and your team make my life easier. "

Frequently Asked Questions

Aside from creating our own custom portal which allows us to provide virtually unlimited customization, the greatest differentiator is that SoundLine™ is essentially a co-op. By capping our future sales to only 3,000 customers and splitting all future profits among our eight team members, you will always have the most attentive and personable customer service ever.

A traditional PBX not only requires a large capital investment and a physical server to exist in your office, but also does not have the redundancy provided by our cloud system. When your PBX is hosted in the cloud, it essentially can never go down. No matter what happens at your location, calls will still route to employee cell phones and/or a different location that still has internet. This means you’ll never miss a call!

SoundLine™’s porting department is known throughout the industry for our attention to detail and determination to get your number ported on time, every time. We even set up your phones to work prior to the port so, once the numbers transfer to our network, you won’t even know that it happened.

The wonderful thing about our training is that we only need to train you on how to use your phones, and never on how to program anything; we do all of that for you. After a thorough consultation, we will program and test your entire system before shipping. Once you receive your phones, simply call us and we will go over everything in as much detail as you require. After that we are available 24/7.

Since our inception in 2008, SoundLine™ has always believed in month-to-month service. If you’re not happy, we’re never going to force you to stay with us. This is because we are confident in our exceptional customer service and proud of our 95% customer retention rate.

SoundLine™ offers the most unique pricing in the industry. With each MBXLite, you can be on one phone call per every two phones. With MBXPro, you can have unlimited calls per phone, which is ideal for queues and high call volume applications.

Of course. SoundLine™ can provide support to any SIP-IP enabled device. If you are not sure if your device is SIP-IP enabled, then give us a call to explore your options. We reserve the right to charge up to $50 per device to remotely provision them. When you purchase phones directly from us, we sell them at cost. We also send you plug-and-play phones with a two year direct-replace warranty, guaranteeing the smoothest possible transition.

The reason SoundLine™ created our own portal is to support multiple locations better than any other provider. Our “class” system allows us to designate different 911 addresses and failover settings for every single extension, regardless of their physical location. On top of that, you can transfer with one-touch to anyone, and see the status of their line. This makes managing multiple locations a breeze. Plus, only paying one bill, for obvious reasons, is pretty cool!

SoundLine™’s system architecture was designed in house from the ground up with a focus on security and redundancy with no single point of failure. Our servers run the latest CoreOS Container Linux and our services were designed with a microservices architecture and continuous integration for fast iterations. This produces the world’s most feature rich phone system. Our network architecture has no overlay networks to add latency and complication, which are very common with cloud platforms and container networks. We take security very seriously, which is why we offer TLS and SRTP to any customers who want it at no additional charge.

SoundLine™ offers a 30 day money back guarantee. We have thrived this long without contracts due to overwhelmingly positive customer experiences. When you’re happy, we’re happy, and the last thing we want is for a customer to leave us on bad terms! Thus, we are always happy to provide references and encourage you to research our reputation online.
