hi all, I'm using Elastix 1.6-12. When I make a call with IP phones and hear the IVR: "please push 1 to XXX, 2 to YYY", and then I push the 1 to talk to XXX, but it is not detected the digit. So, I can't interact with the IVR of called side. The dtmf mode of the ip phone is set to rfc2833 and the extension's dtmfmode is set o rfc2833 too. How can I fix it?.
