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 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 also have H.323 interconnection available for large carriers. Please use our contact form for such inquiries.
We currently accept payments through Amazon Payments. We also accept wire transfers for larger payments.
You may visit our DID page for more details on what area codes are currently available.
Yes, we allow ports both ways. Port orders to Flowroute are $25 for either a single DID or up to 100 contiguous DIDs. Please send your port order requests through our contact form and we'll have someone contact you to complete them. We will have an automated port order form on our Flowroute Manager interface soon.
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:".
Yes, unlike many other providers we terminate toll free NANPA traffic free of charge.
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.
No, we take our customers' privacy very seriously and do not release customer information unless we are legally required to do so. Please see our Privacy Policy for more details.
You can view in-progress calls, call records, and remaining balance in realtime once you've logged into your account.
No, at this time our services are all strictly prepaid.
We use the E.164 format: "[CountryCode][Number]"
Examples:
NOTE: DO NOT dial NANPA (Country code +1) calls using 10 digit format (NPA-NXX-XXXX). It will be recognized as an international call.
For most international destinations we can handle burst traffic in excess of 1000 simultaneous sessions. Simultaneous sessions may be restricted for accounts with low remaining balances.
