Hi is there any one who can help me solve this very appreciate. I use fanvil x5 desk phone to make an external call if the person is busy the fanvil phone will keep ringing without any statement. I capture from the fanvil phone only saw 3cx tell 180 ringing Then when I use 3cx app to call that person again I can hear the statement of that call is busy please try later. I capture from 3cx system and also there is a 183 session. I am wonder if there is a setting in 3cx or fanvil phone I can change to let me hear the statement? Thanks a lot.
