  Cool!, but that doesn't include ABCD. https://pbxbook.com/other/dtmftone.html https://pbxbook.com/other/dtmftone.html does. I'll try a company I know takes at least 40 minutes usually : Also, something that annoys me about VOIP is that they don't take into account the different tones in different regions. Here in the Netherlands we use 425Hz fo dial tone etc. It always feels very emulated because it's a different tone.
