With SP4, 3CX Phone System is ‘Microsoft Ready’ and works with Windows Server 2012.

New Features and Changes

  • 3CX Phone System is now a Microsoft Ready Platform and works with Windows Server 2012
  • We’ve increased the amount of call logs in 3CX Web Reports to 500000 records
  • A Portuguese language file has been added for 3CX Reports.
  • Fix in extension scheduling and toggling between Profiles and status.
  • We removed the ability to edit phone provisioning templates in the Web Management Console – phone templates can only be edited via Winforms management console.
  • IVR Pin protect extension is now set to 77,777,7777 and 77777 on all installations.
  • You now have the ability to rename an extension group and to rename the management group.

  • 3CX Phone System will now check Windows Event log Service to make sure it is running. This will avoid spamming of email notifications sent in the past.

  • It’s now simple to create a VoIP Provider Trunk Mode as only the external number is needed.

  • We’ve fixed a bug in how missed, transferred and ring group calls are represented in 3CX MyPhone.
  • We’ve added the ability to control Snom Phonebooks to either erase and re-provision the phonebook, or update existing entries.
  • We fixed a bug where the Update Extension provisioning file wasn’t always being updated whenever a PNP request was sent.

    Still had to use processexplorer to find 3cxeventlog.dll under a svchost and kill it during upgrade, failure to do this means the upgrade fails arnd rolls back.

    • @Brian – Can you see the path of the process? From there you should be able to see which component was running in svchost. Since you can have multiple svchost processes (same name) it is going to be difficult to find which process was running in that svchost instance at that time. Something external from 3CX is loading 3CXEventlog.dll (this could be something else that READS from the global windows event viewer). It can also be a HyPer V Management console. We are checking for processes mmc.exe but there are other applications. Clearly something that is happening on your machine so it has to be investigated on a per machine basis.

    One of our larger clients had resisted upgrading from Ver. 10 to Ver. 11. Yesterday afternoon at 4:00 PM we started the upgrade to Ver. 11 SP4. All went extremely smooth with this 128SC customer that has over 200 on site handsets and another 30 remote phones. He was very happy that the separate backup of voicemails and recordings allowed for a few hours of upgrade time vs. the six or seven that he experienced with other PBX’s over the years.

    We have now updated all of our managed clients to Ver. 11 – SP4. Great job 3CX team!

    In Sysinternals proccessexplorer I can Find all processes using a particular file. Searching shows me that 3cxeventlog.dll is used by a svchost, 3CXPhoneSystem.exe and 3CXCallHistoryService.exe

    Examining the svchost shows that this particular svchost is providing AudioSvc, Dhcp, eventlog and lmhosts. There is nothing else in the properties of this svchost which gives any clue what is using your dll. I am not certain but I think this has only happened after the first install of version 11, could it be linked tothe music on hold service?

    So I can do the upgrades since SP1 by setting the upgrade running and killing the svchost which has the dll in use.

    I am not complaining about this issue here but I recall seeing quite a few people in the forum were stuck on rolling back when trying to go to SP2 and 3 and after examining the logs I found that the 3cxeventlog.dll could not be (deleted or written to, cannot recall) during the upgrade so I started looking at what was using it. Maybe this will be useful, maybe not!

  5. Upgrade to sp4 went fine except for three things, shared parking and extension queues would not register and ended calls remain in myphone. Otherwise nice work as usual!

    • @John – did they register after a while but?
      Are you sure your license is valid? Seems like the pbx went to free mode…

    Any word on when a Windows Phone client will be made available?

  7. I would have to agree with John on SP4 we have had a few issues after the upgrade with call transfer from the phone, Parking and also ended calls remaining on the MyPhone screen.

    Internally we are using Yealink, Aastra and Snom handsets. I have seen the issues first hand on a Yealink T38G running Firmware as this is the phone I use most of the time when in the office.

    Has anyone else had these sorts of issues after upgrading to SP4?

    Glad to have support for Outlook 2013 now :-)

    • @Stuart – Absolutely nothing was changed in that area. Can you restart the server. We did very little changes to the core. Maybe you have some stale cache in the myphone and calls are showed stuck.
      We have no reports on this.
