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: http://saevolgo.blogspot.nl/2012/07/asterisk-behind-kamailio-voicemail-mwi.h... that appears to work for me.
