On-Demand Cloud SIP Trunking Service Provider
Low Cost – Self-Service – Flexible – Reliable
Who Are We
SIP.US is a business-class SIP trunk service provider for IP-PBX systems and analog/digital telephone adapters. Our SIP trunks operate on your own broadband Internet connection, and we offer unlimited rate plans. Our easy setup, Tier-1 network, and powerful self-service SIP control panel have made us the leading on-demand SIP provider.
Tier-1 Redundant Network
SIP.US utilizes only Tier-1 upstream providers to route our SIP traffic. We do this to ensure that you get the highest quality voice experience and a redundant network for outstanding reliability and performance.
Powerful Self-Service Controls
SIP.US puts you in control by providing an easy to use interface that lets you manage all aspects of your SIP account including, adding or changing your service and reviewing or exporting real-time call data records.
Bring Your Own Bandwidth
Unlike other SIP providers that require you to get bandwidth from them, we offer you the flexibility to choose the bandwidth supply you prefer. Cable, DSL, T-1 or Metro Ethernet, the choice is yours.
If your company uses automated dialing for telemarketing, unlike most other SIP service providers, SIP.US can connect you with upstream carriers who welcome this type of traffic and help you avoid dialer surcharges.
Simple SIP Pricing – No Contract
Paying for your VoIP trunk is as easy as setting it up. Our SIP service is prepaid with no contract and a rate of $24.95 per month per unlimited channel. Add channels or cancel anytime.
Toll Fraud Protection
With VoIP, international toll fraud can be a significant problem. We protect our VoIP SIP trunks from fraudulent activity by using automated systems that help detect fraud and protect your account even if your on-premises systems are compromised.
We are able to get our Switchvox systems up and running with SIP.US in a matter of minutes using the simple online interface.
Mike Crockett, BITS Technology
I don’t have any experience with SIP trunking, but connecting my Asterisk PBX to SIP.US was fast and easy.
Eddy Pareja, Sangfroid Web Design
The SIP.US Control Panel gives me all the tools I need to add, change and delete phone numbers. I can even order all the DIDs I need and set them up instantly. I love having access to these self-service tools, but I know the support team is also there if I need additional help.
Colin Cook, Thimble River
I wasn’t sure how to configure my Asterisk system to work with SIP.US. The SIP team was able to remotely access my system and set it up for me. I didn’t expect that level of support for such a low price.
