I have seen this error a few times but have had no success at fixing it.
Asterisk 20, FreePBX 17.
asterisk-voicemail-20.15.2-1.el8.x86_64
asterisk-voicemail-imap-20.15.2-1.el8.x86_64
asterisk-voicemail-odbc-20.15.2-1.el8.x86_64
We have a single mailbox that is at the end of a RingAll group and that all can access. On our earlier version (FreePBX 15/16 & Asterisk 13) it worked very well.
module show like voice

Wen we dial the mail box with *98 we can see this error:
[2026-06-15 18:19:32] WARNING[186727][C-00000008]: pbx.c:2943 pbx_extension_helper: No application ‘VoiceMailMain’ for extension (from-internal, dvm9999, 7)
asterisk*CLI> module reload app_voicemail.so
Module ‘app_voicemail.so’ reloaded successfully.
core show application VoiceMailMain
Your application(s) is (are) not registered
Command ‘core show application VoiceMailMain’ failed.
Doesn’t appear to be any obvious reason the app won’t load and I can’t see any other errors to point me in the right direction.
Any thoughts on where this is failing would be appreciated.
