So I can dial *120 and I do hit comedian mail so that does work.
If i run /usr/local/fop2/autoconfig-buttons.sh the relevent line for 120 is shown as
extenvoicemail=*120@from-internal
fop2 manager has "*120@from-internal" in "Extension to Voicemail" section
So that all appears correct, what would be the next step to get troubleshoot this?
Edit: all good, got it sorted
