Modern features. Fast set-Up. Flexible control.
SIP.US Platform Features
Now, it’s easier than ever to modernize your communications with SIP.US. Our built-in features provide everything you need in one streamlined platform to give you control, reduce costs, and support today’s diverse workforce.
Powerful Control Panel
Use our robust, easy-to-use control panel to manage all aspects of your account. In minutes, you can purchase and manage phone numbers; add, change or discontinue service; review and export real-time call data records, and modify your billing preferences.
Most SIP trunking providers avoid dialer and telemarketing traffic. We have special arrangements with upstream carriers who welcome this traffic. Simply identify this in your trunk settings to avoid surcharges for dialer traffic on our regular service.
Real-Time Call Data Records
Call Data Records (CDRs) bring visibility into your usage and true communication needs. View your CDRs in the Control Panel in near real-time. View today’s records or the past year. You can also download the records as a .CSV file.
Widespread DID Coverage
SIP.US offers a large database of numbers across the US and internationally. Easily search our database and order numbers. Most DID numbers can be provisioned instantly. We can even backorder numbers if they are unavailable in your area.
Choose your own broadband Internet provider, from cable, DSL, T-1, or Metro Ethernet. Each G.711 IP phone call will consume approximately 85kbps up/down across your network. We also allow the G.729 compressed codec when bandwidth is at a premium.
International Toll Fraud Protection
Our system watches in real-time for international call fraud, taking immediate action to kill unauthorized calls in progress, shut off international calling on your trunk, and alert you and our Network Operations Center of suspicious activity.
Simple SIP Trunk Pricing
Paying for your SIP VoIP trunk is as easy as setting it up. Our service is prepaid with no setup fee or contract. Pay monthly or annually per unlimited SIP trunk channel. Add, cancel or upgrade channels quickly straight from your Control Panel.
Apply nomadic e911 to any US DID number we carry, applying any valid USPS address to any phone number in the US so when 911 is dialed from that number, it will display the associated address to the emergency services operator. Update the address at any time.
We support any SIP-enabled PBX system from popular carriers such as Asterisk, Elastix, FreeSwitch, Cisco, and Avaya. We integrate with any open source telephony application and will help you configure the trunks so you can be up and running in minutes.
Tier-1 Redundant Network
SIP.US uses only Tier-1 upstream providers to route your traffic. You get the best voice quality on a redundant platform to ensure optimal performance and reliability. We also employ multiple gateways across the US to eliminate any single point of failure.
Fault-Tolerant DID Routing
We can route an inbound DID calls to a primary and secondary IP-PBX in case the primary PBX fails or is busy. We also offer the ability to forward the call to a backup PSTN number in the event of a routing failure, all seamlessly configured in your Control Panel.
No Obligation Free Trial
We’re so confident you’ll love our service, we offer free trial accounts that include 60 minutes of outbound calling to anywhere in the US48 to test our service. Once we confirm your email, we automatically create a SIP trunk for you to you start making calls immediately.

Low cost and good!
It’s easy to be low cost, but it’s a lot harder to be low cost AND good! In my opinion, SIP.US should be on anyone’s short list of primary providers.
All the tools I need.
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.
Up and running in minutes.
We are able to get our Switchvox systems up and running with SIP.US in a matter of minutes using the simple online interface.
Quality support, low price.
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.
The Galvin Law Group
Fast and easy set-up.
I don’t have any experience with SIP trunking, but connecting my Asterisk PBX to SIP.US was fast and easy.
