Hello, So, I love the 3CX phone. It works great...mostly. I'm using the 3CXPhone on my EVO to register with my FreeSWITCH server. I can place calls and everything works great, except when I'm using an IVR (i.e. Voicemail, Front end Menu, etc.). When I am in a call and need to press a number to respond, it double taps my key and the menu doesn't understand my response. I've tried the echo cancellation feature, but it didn't help. Does anyone have any experience with this? Or more importantly know how to fix it?
