I have a client wanting SIP trunks as a fallback for their PRI. We will to connect over their existing Comcast Internet connection.
We have talked to a couple of providers, but need to know how well they work (or don't work). Which U.S. SIP providers have you had the best experience with?
Thanks,
Frank
