asterisk - mysql

Hello, I'm using Asterisk 1.2.X I would like to link it to a MySQL server <b>that is installed on a separate server</b> and to use the external database for 2 purposes: 1. Set all the extensions that are currently listed in [login to view URL], the hosts/servers that are listed in [login to view URL] and the [login to view URL] , mailboxes that are listed in [login to view URL] in tables in the database. Any change in the database would need to be applied immediately on the running Asterisk, and voicemail password changes would need to be updated in the database, in case a user changes them through the IVR. Thanks for all Jorge
