asterisk users - Jul 2006 - Message waiting question...

Hi

I have the following setup:

SPA3000 (at home) --> Asterisk1 server (at home) ---> Asterisk2 server
(at work).

The reason the SPA3000 isn't connected directly to Asterisk server 2
is because the SPA3000 can't register to more than one SIP account at
a time, plus it was more fun that way :)

Anyhow, Asterisk1 and Asterisk2 are connected using IAX2.
What I would like is to have the SPA3000 Message Waiting indicator
based on the voicemail message hosted on the Asterisk2 server.

Is this possible?
Thanks
JY

Anything is possible, it's just to what extreme do you want to go to make it
happen. Right now we have no way of transporting arbitrary information (like MWI
status) between servers. In the future however I'm hoping we'll have
something. For now there's two er I mean three ways off the top of my head
you could approach this.

1. Using ODBC storage to store your voicemail in a database and have each server
setup against that database. The MWI will just query the database to see if
there are messages, and since there will be... MWI will be sent to the phone.

2. Using the ability to execute an outside application that exists right now and
using your own method to communicate back to turn on MWI (maybe generating a SIP
NOTIFY to poke the phone with?).

3. Share the voicemail directory over something like NFS.

There is this old patch that does remote MWI over IAX (among other
things). I used it on earlier versions and it worked quite nicely.
This was before 1.2 so it may no longer work at all. At the very least
it will likely required some updating. Doable, just depends how much
time you want to put into it :).
