I have been using Re:source-sip for a few months now and I am really impressed. They have an excellent customer service team that is always willing to help with any issues or questions that I have. The SIP trunking service is very reliable and the call quality is great. I would highly recommend Re:source-sip to anyone looking for a reliable and affordable SIP trunking provider.
