Asterisk Voicemail - Quick Exim4 notes

After installing asterisk I set up the voicemail configuration. First un apt-get install exim4 and then run pkg-reconfigure exim4-config and follow the instructions.

After the configuration exim4 should restart itself but if not use /etc/init.d/exim4 restart.

Configure the voicemail.conf file as follows:

[general]
format=wav
serveremail=asterisk
attach=yes
skipms=3000
maxsilence=10
silencethreshold=128
maxlogins=3
pbxskip=yes
fromstring=Voicemail
emailbody=Dear ${VM_NAME}:\n\n\tjust wanted to let you know you were just left a ${VM_DUR} long message (number ${VM_MSGNUM})\nin mailbox ${VM_MAILBOX} from ${VM_CALLERID}, on ${VM_DATE}. The message is attached. Thanks!\n\n\t\t\t\t\n
emaildateformat=%A, %B %d, %Y at %r
sendvoicemail=no
delete=yes

[zonemessages]
eastern=America/New_York|'vm-received' Q 'digits/at' IMp
central=America/Chicago|'vm-received' Q 'digits/at' IMp
central24=America/Chicago|'vm-received' q 'digits/at' H N 'hours'
military=Zulu|'vm-received' q 'digits/at' H N 'hours' 'phonetic/z_p'
european=Europe/Copenhagen|'vm-received' a d b 'digits/at' HM

[default]
89300 => 89300,User1,user1@mailserver.com



Now on Sip.con add the mailbox line (mailbox account and context of voicemail.conf)

[89300]
type=friend
regexten=89300
context=default
mailbox=89300@default
secret=89300
username=89300
callerid="User1" <89300>
host=dynamic
nat=yes
canreinvite=no
disallow=all
allow=alaw
allow=ulaw
dtmfmode=inband


Finally on extensions.conf set each SIP extensions (will use macros later) to wait for 20 seconds and go to Voicemails as follows:

[default]
exten => 89300,1,Dial(SIP/89300,20)
exten => 89300,2,VoiceMail(89300@default)
exten => 89300,3,PlayBack(vm-goodbye)
exten => 89300,4,HangUp()
