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.

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.

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.

Excellent support.
The reason we moved most of our VOIP to you is because of your excellent support. We moved from another provider but your support makes the extra money well worth it.
