How to configure automatic addition of voicemailbox for extensions in asterisk?

Question

Asterisk

is it possible to add automatic voicemailbox for extension to asterisk in voicemail.conf? I have 20 numbers for the operator, all redirected to voicemail and not to prescribe each time if the numbers have changed. Recording everything in one voicemailbox is not suitable (exten => _X.,2,Voicemail([email protected],s)), the mailboxuser needs to be the number that is being called. Thank you!

The extension.conf itself looks like this, it sends all incoming messages to

ectension.conf
exten => _X.,1,PlayBack(hello)
exten => _X.,2,Voicemail(${EXTEN},s)

voicemail.conf
[default]
46765125360 => 12345,

Me_X. => 12345,Me - Is that not possible?
