I’ve been using Les.Net for many years as I found it to be a reasonably priced SIP provider with decent customer service.
I was shopping around a couple of months ago and realized that now they are pretty expensive compared to others so I started checking out other SIP providers, specifically any providers that would also have good API’s and/or integration into my other systems (like my CRM) and found Twilio. Their plans are about 1/2 that of Les.Net and I’ve been running a test account with them tied into my PBX now for a couple of months and it seems to be going well. All of our outbound calls have been on Twilio and we’ve been pretty happy with their SIP service.
I’m curious what others think between these two providers or if they think Twilio is not a good SIP provider.
