To forward calls to an Asterisk Server is not a big deal. However, when you have two or three Asterisk servers processing voicemails it becomes hard to manage users in several different servers. The realtime Asterisk integration allows you to run Asterisk Real Time using directly the serMyAdmin database.  So it doesn't matter how many voicemail servers do you have, you are going to use a single database.  Another important aspect is, all messages coming from your server to Asterisk will be authenticated, so you have an additional layer of security too.

For the release 1.2.x we’ve planned the integration of Asterisk in our solution. Very small modifications were done to the system. The basic idea is to integrate the voicemail users, the voicemail database, sip users and peers. The views should be ready in your system, but for some reason they were not exported in serMyAdmin.sql file of the version 1.2.1. So you will have the follow this procedure to integrate Asterisk to your serMyAdmin installation.

The only modification made to serMyAdmin interface was the insertion of the field "Voice Mail Password" in the user definition.
