A2billing, Openvz & Asterisk Skills

Up for Grabs is a quick Project to rectify an existing installation of A2billing 1.4 stable and Asterisk sitting in an openVZ container. The Environment is in Production and is currently working. The Issues to rectify or do are as follows: 1) The Container would need to be expanded to become a large primary taking 90% of Memory and HDD resource with minimal disturbance. The Server Hosting the containers would ultimately have 2 instances and the Host. The production should eventually take up 90% of the resource leaving the second one as a backup container only. Would require someone with Skills on Ruby and/or openVz on this. 2) The A2billing currently hosted has issues that need to be rectified- Has stopped sending Notifications (suspect sendmail or some service issue). Asterisk Realtime has issues and may need to be either reinstalled or rectified Skills required would be A2billing, Centos admin and Asterisk 3)Callback has problems, The Daemon is running correctly but calls do not get bridged but are dropped. Something in either AGI is missing or is missing because Asterisk has not been installed correctly Requires Skills : A2billing AGI configuration. 4) Payment through paypal works fine but refills do not get automatically updated. maybe something small lacking in global config. Folks this is a Production enviornment, so need someone experienced to touch this. For someone experienced all this may take is a days work.
