3CX Phone System v6 - Beta 1 Version verfügbar

We are pleased to announce a new version of 3CX Phone System v6!

3CX Phone System v6 should prove a major improvement in performance, stability and interoperability. We have also paid special attention to improving the backup and restore and upgrade process.


3CX Phone System v6 - To upgrade your installation:

1. De-install v5.1. For safety purposes, we suggest taking a backup of your configuration first. (this is the last time you will need to do this, next installations will be able to do this automatically)
2. Run v6 set-up. It will automatically convert an existing v5 configuration database to a v6 configuration database. Note that the de-install will remove the program files but leave the old configuration database, this is why it can upgrade it.

Alternatively you can do a clean install and restore a backup. The restore process has been vastly improved – what took hours now takes minutes. Note that upgrades from v3.1 are not supported. Note: Backup and restore requires .NET framework v2.0 or higher.

3CX Phone System v6 What’s new in 3Cx Phone System V6?

All versions

• Improved IVR - Its no longer necessary to specify extension number when you are picking up your voice mail from your extension. It is also possible to listen to own voice mail greeting from the personal voice mail menu.

3CX Phone for Windows System - Build version 5.1.4393 - 2 April 2008

IMPORTANT - THIS SERVER REQUIRES LATEST 3CX VOIP CLIENT. Other wise presence of extensions will not be displayed!

This build includes some new fixes and is also a roll up of previously released fixes.

• Upgrading your old installation
• Upgrading from Build 4128 - Do a backup from the Admin console.
• Save the file.
• Uninstall 3CX Phone System.
• Do a clean install and then after install perform a restore.
  
  Please download the latest version here
• 3CX Phone System SIP Server Version 5.1 (Build 4393)
  
  
  
• Added: Setup file is now MSI instead of Exe. This will facilitate download and installation of future patches.
• Added: Improved Presence functionality using SIP dialog-info
• Added: Support for Aastra 5X series phones
• Added: Support for Linksys phones
• Added: Support for provisioning Aastra phones (support for linksys to be provided over the next few days via internet updates)
• Added: ECM FAX option is enabled by default, reducing the number of truncated faxes.
• Added: maxNoAnswerTimout in general section of ini file - 180 seconds. Overrides Continue ringing option for extensions (included in patch 4287)
• Fix: route for out of Dialog MWI notifications through tunnel. (included in patch 4287)
• Fix: VOIP line re-registration procedure correctly track line status in case of voip provider inaccessible (included in patch 4287)
• Fix: update of voip lines configuration and updating registration status after changing line configuration (included in patch 4287)
• Fix: PBX now drops a call if server leg (UAS on PBX) does not receive ACK from remote party (call hung issue) (included in patch 4287)
• Fix: memory leak in Media Server (included in patch 4287)
• Fix: Fax header declarations (fax being caught as virus by antivirus software) (included in patch 4287)
• Fix: Memory leak in IVR (included in patch 4287)
• Fix: Forked ID presence issues. If 1 contact from a forked ID is busy, all extension is market as busy. Same for away status.
• Fix: Now PBX uses media server SDP if destination of blind(attendant) transfers is bound to Media Server. Old behavior - always use "invite without SDP". This new behavior is
  controlled by "allowNoSDPIfBoundToMS" ini file option. Default value is 0 (new behavior). To revert to previous behavior set this option as [General] allowNoSDPIfBoundToMS=1
• Fix: For ring group. Now RTP mode corresponds to extension settings (PBX delivers audio, support re-INVITEs). Previously proxy/bypass mode was used for all extension even if they are bound to Media server.
• Fix: Media server doesn't "spam" trace log with "Can't receive RTP packet" message.
  
  
  General notes
• If you are using a VOIP provider, your router must be configured with STATIC PORT MAPPING for 5060. Incorrectly configured routers that are doing port translation rather then port forwarding are a cause of failing inbound calls, one way audio and so on. To check whether your router is doing port address translation run the firewall checker.
• If the PBX machine has multiple interfaces, and the fax service is being used, you must specify the IP in the 3cxphonesystem.ini file for the fax service.
  Interop notes
• We have added support for the Aastra 5X series phones
• We have improved support for Linksys phones
• Latest Grandstream firmware resolves all BLF issues and BLF now works well.
  
  Upgrading your old installation
• Upgrading from 4128 - Do a backup from the Admin console. Save the file.
• Uninstall 3CX Phone System.
• Do a clean install and then after install perform a restore.

• Added a tunnel, which allows all SIP and RTP traffic to be tunneled via a single, configurable TCP port (by default 5090) Currently this tunnel can be used for bridges between phone systems and by hard phones on remote networks (which have to use the tunnel as an outbound proxy). The tunnel will also be included in the next version of the VOIP client, due out soon.

• Fixed: Bug where a call could potentially remain stuck in the system and be displayed as active in the interface, even though the line would have been disconnected
• Fixed: Improved the patton 4554 template
• Fixed: Caller ID is now correctly passed to Patton devices
• Known issue: Affects calls via tunnel only: Call Transfer from a phone behind a tunnel, back through the tunnel will not work

General notes

• If you are using a VOIP provider, you router must be configured with STATIC PORT MAPPING for 5060. Incorrectly configured routers that are doing port translation rather then port fowarding are a cause of failing inbound calls, one way audio and so on. To check whether your router is doing port address translation run the firewall checker.
• If the PBX machine has multiple interfaces, and the fax service is being used, you must specify the IP in the 3cxphonesystem.ini file for the fax service.
  

  If your machine has multiple network interfaces, you must specify which IP the fax service must bind to. To do this:

  1. Open the 3CX PhoneSystem.ini file, located in the 3CX Program Files directory.

  2. Create this entry:

     [Fax]

     serverHost = 10.172.0.2

      where the IP must match the IP to which the fax service must bind.

      This IP must be on the same subnet as the VOIP gateway!
  
  Interop notes

• The following interop issues are known to exist and are not issues that 3CX can resolve:
• Grandstream GXP2000 1.1.5.15 - Music on hold does not work well, Grandstream firmware issue
• Grandstream GXP2000 1.1.4.18 - BLF does not work well, Grandstream firmware issue
• Polycom 550 2.1.2.0078 - Music on hold does not work well, Polycom issue
• Aastra phones continue to have numerous problems - do not use!
• Grandstream GXW4104 gateway - must be switched to PBX delivers audio for forwarding of calls to outbound numbers to work. This is an issue relating to Grandstream. This is not compatible with the fax feature unfortunately.

Upgrading your old installation

Backup and restore has been greatly improved in cases where customers wish to backup Call History. However, to benefit from these improvements, you need to update your old installation first and perform the backup using the new backup and restore functions.

To do this, download the updated PHP filesand extract the file here C:\Program Files\3CX PhoneSystem\.

This should replace the following files:

• C:\Program Files\3CX PhoneSystem\Data\Http\backup.php
• C:\Program Files\3CX PhoneSystem\Data\Http\support.php
• C:\Program Files\3CX PhoneSystem\Data\Http\functions\BackupParser.php
• C:\Program Files\3CX PhoneSystem\Data\Http\functions\BackupManager.php

Then perform the backup as usual and restore after you have installed 3CX Phone System v5.1

Note: if you want to avoid downloading and installing the files, you can simply backup and restore WITHOUT CALL HISTORY. In this case the update is not required.3CX VOIP Phone Client  Build version 5.0.4034 - 1 Februar 2008 (BETA 6)
