Some terminals will dispatch an acceptance message in reply to the sent notification and others will not. This means an acceptance message will only show up in your screen for terminals that dispatch said message. An overview of terminals which do and do not send an acceptance message is available here.
In this overview, you can determine for each terminal whether it supports an acceptance message (also known as a return message). You can find this information in the line ‘MID return message possible?’ Yes/no
You can change your permissions via 'customise preferences'.
