Leaving a Zoom voicemail message

[KLEA]

I left a voicemail message using Zoom phone to another Zoom phone user.  I did not press a number on the dial pad after recording the message, I just hung up the call. 

The person I called told me afterward that the voicemail message was "...45 seconds of nothing".  

Do I need to 'press a number on the number pad' after recording a voicemail?
