iSymphony 3.0.3 serves as a patch release to resolve several bugs and includes client side push efficiency improvements.

Improvements

• The push system has been modified to restrict the amount of push events that can be sent from the server to the browser, within in a specified amount of time. This provides a large increase in UI update efficiency when handling several UI updates at once, as the overall overhead for handling push events is decreased. This modification also significantly reduces Javascript processing time, and resource consumption, in the browser.
• Modified the automated upgrade mechanism to display links to the upgrade notes, release notes, and change log, for the available upgrade version,  under the upgrade button.
• Added a warning to the administrator interface to inform administrators if their maintenance expiration date has expired, or that it is about to expire.
• Added a warning to the automated update area to inform administrators if their license does not support the upgrade due to maintenance expiration.
• Added a Tenant Identifier field to the top level Core Server configuration that is utilized to specify which recordings belong to the core server's tenant.
• Added a new recording filename mask variable ${Tenant} that can be used to identify which tenant a recording belongs to.
• Added the auto answer header "Alert-Info: ring-answer" in order to support older Digium phones.
