[Serusers] SER proxy and SER+SEMS media server

[Teemu Harju]

Hi,

I'm implementing following kind of system. I have two separate machines 
where I've installed SER on. The other machine has also SEMS installed. Like 
you probably already figured out other is used as a plain proxy/registrar 
and the other as a sort of UAS serving voicemail, conference etc with the 
help of SEMS.

Now my question is, what is the best way to forward messages from 
proxy/registrar to the media server? I've done the forwarding according to 
the examples I've found and it uses rewritehostport() to forward messages to 
voicemail. Voicemail needs to get the email address from mysql database 
located in proxy. This is no problem connecting to the database, but isn't 
it so that when I've rewritten the Request-URI that the voicemail cannot 
find the email from database beacause it's rewritten and has the media 
servers host part in the URI.

How have you guys implemented this? I would also need other SEMS plug-ins 
like conference, so I would also need to differentiate those requests also. 
Could I rewerite the Request-URI like voicemail at mediaserver? Can the 
voicemail still find out who was I actually trying to call to since the URI 
is rewritten?

Is there difference in implementing the media server with asterisk? Wouldn't 
I need then two different databases? One in asterisk and one in SER.

Thanks...
