[Freeswitch-dev] Force voicemail number in the standard voicemail greeting

[Mikael A. Bjerkeland]

Is there a way to alter the number spelled out in the standard voicemail
greeting? Instead of saying polycom501 which is the mailbox I'd like it
to say 21650994 by setting a variable before calling voicemail.

I found the voicemail_greeting_number variable, but setting it does not
have the desired effect.
