Hello, I setup my 3cx v15 system a while back and all has been working correctly since. I have the Digital Assistant and when the caller dials 1 this usually takes them to call by name which use to work. My last name is "Sa" so I was looking in the forums for how to make it so that the minimum letters someone needs to press to find me is 2 instead of the default 3. I found a thread which led me to change the setting "CALLBYNAME_MINLEN" to 2, however after I did that, when a call the main line and press option 1 for "Dial by name" the line drops. I even reverted the setting back to 3 and this continues to happen. Any assistance would be appreciated.
