PJSIP and MWI for mailbox (FreePBX 12 and Asterisk 13)

thank for posting the screen shot but where is this setting buried in FreePBX? I’m really unable to find this section anywhere. Can you please post something like:

Applications->Extensions->click on extension->click on tab “VoiceMail”

I’m definitly looking somehwere else the you people who know it. Or does this not exist for chan_sip devices?
