In 3CX’s  latest update, aptly named “5” , 3CX has added a new host of features and made numerous improvements to their most successful version to date – v15.5.


Below a small outtake of the biggest changes :-

New Trunk/DID report
The new trunk/DID report allows you to quickly see the number of inbound calls to a trunk and to DIDs associated with it.
You can filter out calls that are less than X amount of seconds. These calls would skew call statistics. The filter is available on all reports.

Generate reports on multiple queues
​
Update 5 has the ability to generate reports on multiple queues and merge the data into a single report.

Call recording features
​
The call recording abilities allow the administrator to get more control over call recording:-

• Enforce call recording – control whether the user is able to stop/pause recording or not.
• Ability to record external calls only (i.e. avoid internal calls being recorded).
• Save recordings in ADPCM format, which saves disk space.

Corporate Chat
​

Administrators can now switch off chat for all users system-wide.
Emergency dialing (911)
15.5 supports emergency dialing, extra improvements from 3CX include:-

• Configuration per group – or range of extensions – Examining emergency number used in the outbound rule.
  This greatly simplifies configuration.
• Emergency calls no longer go against the license limit – they can always be made (providing your SIP trunk has the capacity).

Forgot password

Many administrators forget their password to the management console.
A forgotten password feature now allows a password to be sent to the administrator’s email address.

Replace License Key
​
This feature is a big time saver for users wanting to upgrade from a trial to a commercially licensed system.
Previously one would need to do a re-install if the key was not upgraded.
Now you can simply replace the current key with the purchased key and retain all user settings.

​Blacklisting Improvements
​
For security purposes 3CX will blacklist IP addresses that are repeatedly entering wrong user/password combinations.
However, in previous versions it was not easy to figure out which device or who was the culprit.
Better notifications now allow the administrator to quickly find the guilty party and block the IP or fix the issue.

Other improvements include:-

• Backup to Google Drive – we have updated to the latest Google API (1.32) which improves performance and reliability
• Updated to .NET Core to 2.0.7 – this fixes issues with processors that do not support AVX extensions like Intel NUC, Celeron processors and anything not in this list
• Improved Email Notifications to admins to be clearer and explain what to do.
• Increased number of available internal parking slots to 250
• Default configuration now allows up to 1024 calls
• Fixed an issue in the reporting of the attended transfer duration
• Improved voice mail delivery
• Improved “P-Asserted-Identity” support
• TLS 1.2 support – 3CX is fully PCI compliant with TLS 1.2 support. Note that provisioning of some older legacy devices and clients will fail. It is therefore possible to revert to TLS 1.0
• Backup to FTP now supports EPSV
• Yealink T4X template can now provision more than one EXP40 sidecar
• Improved PUSH functionality (much bigger improvements to follow in update 6)
