  Still there are few things i dont understand, i am not
using asterisk
 just as a voicemail server since they are actually handling also the
 calls passing first from kamailio and being load balanced to those
 asterisk boxes. May i still use call forwarding as you are using it?
 (Both asterisk have a shared storage with a clustered filesystem, so
 both will be able to see voice messages) 
Yes I think so. I use a seperate machine for voicemail but I see no
problem with other uses (I used to use it for playback of messages and
transcoding ebtween incompatible endpoints).

By using the prefixes in kamailio to the username in $ru I have in the
extensions.conf:

exten => _tovm-.,1,NoOp(leave voicemail)
exten => _tovm-.,n,Answer()
exten => _tovm-.,n,Set(CHANNEL(language)=nl)
exten => _tovm-.,n,Voicemail(${EXTEN:5},us)
exten => _tovm-.,n,Playback(Goodbye)
exten => _tovm-.,n,Hangup()

exten => _getvm-.,1,NoOp(read voicemail)
exten => _getvm-.,n,Set(CHANNEL(language)=nl)
exten => _getvm-.,n,VoicemailMain(${EXTEN:6})
exten => _getvm-.,n,Hangup()

...
  The other question is that i actually though that you
need asterisk to
 have users configured in sipusers realtime table to associate their
 mailboxes, which i dont have since those users are stored in the
 subscriber table of kamailio. So am i still able to configure
 voicemail like you are doing it by syncing with the voicemail table?,
 i really hope so haha 
I forgot that fact. So yes I have a realtime sip users list (with
host=dynamic,type=friend,insecure=port,invite, name/mailbox the kamailio
username, no password (this machine is not directly accessible from
outside))

You might not be able to have endpoints able to subscribe to
notifications due to this. I baked something inspired by:

that appears to work for me.
