[asterisk-users] bare minimum /etc/asterisk for sip based *

[Eric Fort]

What files at a bare minimum need to be in /etc/asterisk for an
asterisk server that does sip only and voicemail.  I'm setting up an
asterisk server to provide service for a single SIP softphone
extension with SIP origination and termination.  The main purpose of
using * is for voicemail and future expansion ability.

I know I need

sip.conf
extensions.conf
voicemail.conf

but what else?

do I need:

asterisk.conf
codecs.conf
rtp.conf
indications.conf
say.conf
modules.conf
dnsmgr.conf
logger.conf
dnsmgr.conf

if so which of these as well?

Thanks,

Eric
