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
