Who do you recommend for SIP trunking in asterisk? I have a small office with only maybe 3 concurrent calls and need unlimited domestic US minutes. My office is in North Carolina, US. I am concerned about the quality and reliability many SIP trunk providers I find online. Obviously price is important to me but I also need good quality and want a company that's been around for a while. My main concern is reliability. I am hesitant to do away with my POTS lines for that reason. By the way, I have a 3 megabit DSL line. Thanks for the help!
