Jonathan, Cape Print Extensive Coverage and Reach Flowroute provides one of the most extensive coverage areas for telephone numbers and inbound calling in the United States and Canada. And you can leverage Flowroute s extensive international carrier relationships to place calls to virtually anywhere in the World. Direct Audio Flowroute stays out of the way of your call audio. We deliver the call audio stream as directly as possible to the destination carrier s network, leveraging proprietary technology and our vast list of interconnect partners. This uniquely efficient approach to outbound call delivery reduces latency and improves overall call quality. Fax support via T.38 Even as the most reliable standard for fax over IP, T.38 can run into compatibility issues between endpoints. Flowroute normalizes T.38 signaling in real-time to ensure connections aren t lost, and all faxes are delivered clearly. 3

4 Carrier-level Control We recognize that you require a service you can work with to be responsive. Flowroute delivers maximum control of your voice connection by providing open access to the telephone network and giving you the tools you need to manipulate our SIP trunking service to fit your project Scale instantly The capacity you need, when you need it. Flowroute doesn t limit your capacity to handle inbound interactions or require the purchase of capacity that will only be used at peak traffic times. You can always be ready to handle the inevitable bursts in traffic. Provisioning control Use our account management portal or API to provision local and toll-free phone numbers on demand. Customizable Fraud Controls Toll-fraud is a serious threat. Flowroute provides critical protections to keep your account out of the hands of fraudsters. Maximum rate limit: Set your maximum outbound rate limit just above the toll rate to the most expensive destinations you ll be calling. All calls to more expensive destinations will be blocked. Destination whitelist: Calls to all destination not on your list will be blocked. Automatic Suspicious Call Blocking: Flowroute notices unusual call activity. Traffic recognized as fraudulent is blocked. Unlimited Inbound If you have a high volume of inbound traffic, use Flowroute to build a pool of unmetered inbound channels shared by all of your phone numbers to keep costs predictable. Failsafe routing The Flowroute routing platform recognizes when your PBX is unavailable and automatically sends inbound calls to a preselected alternate destination. Number portability Port local numbers to your Flowroute account from virtually anywhere in the US and Canada. Toll-free numbers port for free. Our advanced, highly-automated number porting process has inspired our customers to tell us that, No one else ports this fast. Billing Plans vpri - You need one vpri for each concurrent call you expect into your business. For one flat monthly fee, inbound minutes are unlimited, so vpri pools are ideal for businesses with predictable number of inbound calls and a high volume of minutes. Per-minute - Using this metered plan, you only pay for minutes you use. With no limit on simultaneous calls, you instantly adapt to occasional or seasonal bursts in traffic. Great for unpredictable, or low, inbound call volumes. 4
