External Recordings Server

Configuration

External Recordings Server allows to convert and store Recordings in external server thus increasing storage space on switch server (Asterisk). It will also reduce load on switch server because wav to mp3 convertion is executed in external server.

NOTE: Configuration applies ONLY for fresh CentOS 6 server.

Configuration in GUI

External Recordings Server can be configured in ADDONS -> Recordings -> Settings

Check 'User external Server' checkbox, enter external server IP, SSH port and login username.

NOTE: make sure that servers are configured with SSH keys! Login by password will not work for External Recordings Server.

In SETTINGS -> Billing -> Servers add new server, where

"Hostname for SIP" and "Server IP for SIP" are External Recordings Server IP,

"Type" is "Other",

"GUI" and "DB" are disables (red cross).

Configuration in Database server

In Database Server create MySQL user for External Recordings Server:

 CREATE USER 'mor'@'IP_OF_RECORDINGS_SERVER' IDENTIFIED BY 'mor';
 GRANT ALL PRIVILEGES ON `mor`.* TO 'mor'@'IP_OF_RECORDINGS_SERVER' WITH GRANT OPTION ;
