Hello All, I've a small lua script which is just an IVR. Calls are landing on Asterisk and then they are relayed over to FS. The problem is that the IVR don't always detects what user pressed. What I've observed is that the DTMF threshold is very high and some people just press slowly/quickly and the tone duration gets low and FS don't detect anything. I've rfc2833 set for the sip trunk between asterisk and freeswitch. I've also liberal-dtmf set in my sofia external.xml profile file which somewhat got me better results but still DTMFs miss sometimes. Please note that the asterisk on which the calls are landing have never faced this issue before. Asterisk has PRI from which it receives the calls and then relay to desired FS server. Regards. Sammy
