We have used Flowroute for several years. All along we have been highly
impressed with their call quality, customer support, and price. They have
scaled with us as our business has grown. We recently discovered their APIs
which has been a godsend for us – because we can now manage our phone
numbers in an automated fashion. Another important factor for us was to have
SMS. Flowroute’s Messaging API solved that gap for us – although you do
need to have some developer skills to implement.

Easy to use online portal, APIs, super helpful customer support, and the reliability far better than other providers I have worked with
I wish there was an interface to send/receive SMS

The Skinny

Flowroute's software product line is based in two main areas: Voice (SIP-based solutions) and SMS. 

For voice, Flowroute helps to effectively route inbound/origination and outbound/termination to make for clear, reliable, and high-quality connections.

In regards to SMS, Flowroute possesses carrier-grade SMS capabilities that allow for toll-free and long code messaging, number provision, and access to SMS records.

They also offer APIs to allow businesses to control and customize select parts of their business phone system. Through Flowroute's Numbers API, developers can build voice capabilities right into the cloud. It also lets developers acquire phone numbers, dynamically route calls, and achieve advanced call control. And with the Messaging API, developers can integrate text messaging capabilities into their communications system, too.

the rub

The Rub

When it comes to voice services and solutions, Flowroute offers carrier-grade SIP trunking for IP-PBX systems on top of their reliable network. Their solution ensures that customers always receive clear inbound and outbound calls. Their inbound SIP trunking/origination comes is served with unlimited concurrent call capacity, which is important for businesses that have high call volume. Additionally, their outbound SIP trunking/termination routes the audio over the shortest path, thus increasing call quality and lowering costs.

Plans and pricing are based on the number of phone numbers, inbound calling, outbound calling, and more that your business desires.

To boot, Flowroute offers businesses four number options: port an existing number, choose a unique vanity phone number, choose a toll-free number, or select a local number.
