How to make a change in the VoiceMail Asterisk 11

Question

New to asterisk, and have to support an old installation. If I need to change the voicemail options, is the only way to change the./usr/local/src/asterisk/apps/app_voicemail.c file?

After changing it, how would I go about it?

This is what I gathered from my research:

You need to run:

./configure

make menuconfig (and adjust the settings to match your current system)

make

make install

all as root

I am also horrible at Linux, so can someone enlighten me on the process to change VoiceMail config?

Answer 1

app_voicemail have no settings for changing options.

You can rewrite it using AGI or can rewrite source code. Both will be offtopic here(not one page).

Here is all options you can control without coding:

pro-sip*CLI> core show application VoiceMail
