Introducing 3CX v16 Alpha and Updated 3CX WebMeeting

Review of the new version of 3CX v16 Alpha

Before the beginning of the New Year holidays, we are working hard on the newest version of our PBX 3CX v16. In it we will present both new interesting opportunities and improvements of the old ones. And now we offer an overview of the new system and the Alpha-version for testing!

New features of 3CX v16 Alpha

New features introduced in the Alpha-version of 3CX v16:
')

• Enhanced integration with Office 365. One-sided (Office 365> 3CX) synchronization of Office365 users and extension numbers (users) of 3CX, synchronization of personal contacts, and setting the status of a 3CX user depending on Office 365 calendar events. Maintain only one user directory!
  
• New strategies for the distribution of calls in the queue on the skill level of operators. Operators can be divided into qualifying groups and set a call distribution strategy for groups.
  
• Enhanced IVR features: script support, various actions on DTMF input, additional integration capabilities with third-party systems.
  
• Revised Call Queue module. Laid the foundation for supporting large call centers with a large number of Queues and an intensive flow of calls.
  
• The report module has been revised and optimized to meet the standards of the call center analytics.
  

Improvements in 3CX v16

In 3CX v16, improvements were made to mobile clients (now called 3CX applications), Web client and WebMeeting web conferencing:

• Android and iOS apps:
  
• Web Client:
  
• WebMeeting:
  

Security enhancements

The architecture of the PBX, designed to work in the cloud, imposes maximum security requirements. We added new security features to the v16 kernel to make the life of the system administrator a little calmer:

• Automatic daily update of the black list of IP addresses from the global online directory supported by 3CX.
  
• Export / import IP Block List. You can import it into another PBX or your firewall (for example, Mikrotik).
  
• The ability to limit access to the PBX management interface for specified IP addresses. To do this, added a new tab Restrictions (Restrictions).
  
• In the server interface, you can now choose which particular password or user PIN should be reset.
  
• To enhance security, 3CX v16 before passing SIP authentication now no longer sends the User Agent header.
  
• Improved notifications for extensions with security issues.
  

Platform Component Updates

3CX v16 consists of separate software modules. Some modules are open, and some are designed by us from scratch. Due to this approach, high resiliency of the platform is achieved - an error in one module will not affect the operation of the system as a whole. In addition, this architecture allows modules to be updated independently as new technologies become available. In 3CX v16, all platform modules have been updated to the latest releases:

• The latest version of Postgres DB is a reliable, productive database.
  
• The latest release of OpenSSL v1.0.2o with security fixes.
  
• Compiling kernel on VS2017 ensures the relevance and portability of 3CX code.
  
• Updated .NET Core framework improves performance and security.
  
• GCC 6 - optimized code and improved security.
  
• Debian 8 is finally being decommissioned. We recommend upgrading your installation to Debian 9 Stretch or using the new ISO image of Debian for 3CX.
  

Known issues in 3CX v16 Alpha

1. All scheduled reports in PDF format will be converted to HTML.
   
2. Before connecting to the updated web client, you must clear the browser cache.
   
3. The function of running scripts in IVR requires the installation of an English set of system voice messages. Sets in other languages ​​will be added later.
   
4. 3CX installations on Linux can be updated directly from 3CX v15.5 Update 6 to v16. Be sure to make a backup before upgrading!
   
5. When accessing the SIP Event Log, an exception may occur. Install Visual C ++ Redistributable 2015.
   
6. WebRTC-softphone is already enabled by default.
   
7. When setting the user temporary status, the selected status may not be updated.
   
8. User status via Bridge 3CX may not display correctly.
   
9. If the call center operator uses the call forwarding rule to a mobile number, the Queue name is not added to the Caller ID.
   

Install Alpha Version

You can download the Alpha version of 3CX for Windows and Linux (on Linux, select Beta on the 3CX Update screen). You can also install 3CX directly in the cloud using the PBX express wizard. In this case, you will immediately receive a cloud PBX that is configured and ready for operation!

Do not install the Alpha version in a working environment. Use it only to test new features. Backups made on Alpha versions will not work. In addition, it does not apply technical support regulations.

Participate in a WebMeeting conference from a regular phone

The new version of WebMeeting has the opportunity to simply call the conference from a regular phone! We called this feature 3CX WebMeeting Dial-In. It should be noted that this function has long been requested by our clients who actively use conferences.

At your PBX, you allocate a phone number for calls to the conference. Participants who are out of the office - on the road, at home or simply do not have a smartphone or PC at hand, can connect to the conference simply by calling this number. For this, a special WebRTC gateway has been added to 3CX v16, connecting your PBX 3CX and WebMeeting cloud.

When a user calls the conference, but nobody has connected to it yet, the call is held on your PBX. As soon as regular users connect to WebMeeting, the gateway connects you to the conference. Connections are managed by the conference creator through the 3CX web client.



Calling DID (a) and conference ID / PIN (b) numbers are now added to the conference invitation. A quick copy button for the conference link © is also added, as shown above.

User interface improvements

In the new version of WebMeeting, the participant and chat windows have become a bit bigger. Also, each participant has a volume control - a very convenient feature during the conference.

Adaptive video quality

Previously, if you had problems with a network connection, often you were simply “thrown away” from the conference. However, in the new version we added the adaptive video setting (Video Adaptiveness parameter). When the connection is unstable, the system automatically lowers the quality of the video, but does not turn you off. By reducing video quality, WebMeeting can support a conference even with 20% packet loss.

The conference organizer has three presets: Stability, Balance (default) and Quality. Video quality is maintained at 25%, 60% and 80% of the original. Thus, you yourself determine how you can reduce quality for the sake of connection stability.

Basic and extended conference statistics

Administrators are often interested in the traffic consumption of a WebMeeting conference. For analysis, use the new network statistics panel (section "Parameters"> "Statistics").
For advanced users, extended statistics with detailed information has also been added: video resolution, bit rate, information on incoming and outgoing traffic, connection to the cloud server, etc.

Limitations of 3CX WebMeeting

• Participants who called by phone do not have extended rights to the conference (installation of roles, chat, etc.).
  
• The audio quality for the “telephone” participant is reduced as the codec switches from HD Opus to G722.
  
• At the moment, WebMeeting on-demand (ad-hoc) conferences do not provide for connecting participants by phone for security purposes.
