We are a carrier-grade wholesale VoIP provider offering high-quality SIP trunking and DIDs (phone numbers) at the most competitive rates. Our service is very flexible and scales down from the VoIP hobbyist, up to the largest call centers.
We run a prepaid service where you must keep a positive account balance to avoid service interruption. You can purchase services while logged into your Flowroute account and funds will be debited from your account balance. We'll give you $0.25 free test credit when you signup. After you've used it you must make a $35 opening deposit to continue using services. All deposits you make after that must be at least $20.
At the moment we only support SIP.
We currently accept payments through Amazon Payments. We also accept wire transfers for larger payments.
Please visit our DID page for more details on what area codes are currently available.
Yes, we allow ports both ways. Port orders into Flowroute are $25.00 for single-number orders. Port orders with up to 100 contiguous numbers are $25.00 for the first number plus $5.00 for each additional number. Once logged in, customers can submit their port requests using our automated LNP submission form.
We pass Caller-ID, but do not guarantee successful transmission. We are able to transmit Caller-ID to most parts of the USA and Canada as well as to some international destinations.
We transmit Caller-ID based on the presence of one of the following header fields in order of preference: "P-Asserted-Identity", "Remote-Party-ID" or "From:".

The sip.flowroute.com domain uses SRV records to failover between multiple servers for high-availability. Also, with our cutting-edge architecture, only the signaling path is routed through our sip proxies, the media path is optimized and RTP is transmitted point to point between your servers and our media gateways.
