This is a list of new features in Enswitch 3.11. It is not exhaustive; some enhancements are too minor to list. A full list of features is also available.

• The Enswitch client for Android has a new user interface, and an integrated SIP softphone which automatically provisions from the server.
• The AJAX control panel shows all PBX features in the customer. Calls can be dragged and dropped onto them to route calls to them.
• A plain English description of a call's flow can be produced from the call history.
• Bulk dialer destinations can be retried up to four weeks later.
• Bulk dialer calls can be billed at a different rate then normal calls.
• The Enswitch voicemail can play either oldest or newest message first. This can be set per mailbox.
• The Enswitch voicemail can toggle the temporary greeting on or off.
• Faxes sent from the web interface can include a cover page.
• Telephone lines can have separate internal and external caller names.
• Individual telephone lines can have their daily spending limited.
• The number of concurrent calls to each peer can be limited.
• Alerts can be created for any number of concurrent calls in a customer.

• The system owner can record sounds and make them available to all customers on the system.
• System owner and reseller users can switch between customers faster.
• The call routing and peer pricing tables can be loaded from an external web URL rather than the system's own database.
• Asterisk's ConfBridge() can optionally be used for conferencing rather than Meetme(), removing the need for kernel modules to be loaded.
• Asterisk 11 is used by default for new installations.
• Kamailio 4 is used by default for new installations.
• Kamailio automatically rejects SIP packets from known scanners.
• Outbound SIP calls can include the In-Reply-To header, making it easier to audit and debug call flows using external tools such as VoIPmonitor.
• The enswitch_routed daemon can be restarted without dropping calls in progress.
• The Asterisk Manager Interface (AMI) events produced by enswitch_routed are more logical and consistent.
• Enswitch daemons can use multiple database servers, with automatic failover between them.
