[Asterisk-Users] Enhanced voicemail Externnotify

[Kevin]

Has anyone implemented the externnotify feature that is mentioned on the
wiki with the enhanced voicemail?

I have tried to invoke the command both in the general section as well
as a part of the user mailbox definition with no luck.

The explanation of the feature is as follows:

Externnotify

Want to run an external program whenever a caller leaves a voice mail
message for a user? This is where the externnotify command comes in
handy. Externnotify takes a string value which is the command line you
want to execute when the caller finishes leaving a message.

Does anyone know the proper usage of the feature and can it be defined
for individual mailboxes ?

In this example:

4069 => 6522,Matt
