    It’s exciting to see it getting closer and we’re looking forward to testing soon.

    In version 11, if people use hot desking or SIP clients, 3CX can get confused about where the user is working and sometimes calls don’t complete or get lost during transfers. With the new SIP client functionality / hot desking, will 3CX know to follow the user around properly so calls don’t get lost?

    Is there any way to improve the hot desking so that 3CX automatically logs users off an extension when they log on somewhere else?

    Teh version works good, presence information loads realy fast. But the dutch translation for the 3cx phone is not what it should be. For line 1 , line 2 it is regel 1 , regel 2 etc. this should be lijn 1, lijn 2 etc…

    We will have many users that will have the Windows 3CXPhone and there is still now way to have the call ring on the computer speakers and use the headset for the call. This used to be a feature in Version 11 under Preferences. This is an important feature for us. Will this be added in at some point??? I certainly hope so.

    September 3, 2013 at 10:26 pm
    • @ russ yea of course. This is coming next. If i cannot use the 3cx phone for windows at the moment because of this no problem… Keep the old one for now.

  5. Hi,

    in this version you can join a user into different groups. I think it is a nice feature.
    BUT… You can only see groups if you belong to a group (user or manager). In my company we have different groups. I’m only member of 1 group, but I need to contact the users from other groups.
    A solution: 1 list –> default… But if you have 100 users…
    In MyPhone from version 11 you see the different groups (even if you aren’t a member). This is what we want :-)
    Is it still possible to look for a solution for this?


    September 4, 2013 at 12:10 pm
    • @Filip – Then if you want to see othr groups, all you need to do is get your extension and set it as a MANAGER in the DEFAULT group.
      Then you can do what you like. The default group is a group that contains all extensions.

      September 4, 2013 at 12:38 pm
  6. @Nick,
    but then they are a member of the group? I guess they will appear on the reports for this group?

    September 4, 2013 at 3:07 pm
    • @ Filip – of course they are a member of the group… This is simple Filip – it is designed that you look at the interface and you understand it immediately.

    Back in V12 RC1 you guys had said you were going to look into possibly getting the 3CX Phone Client working on windows XP again.
    Was there a decision made as to weather or not you were going to do this and if it will stay in the final release? I just tested it on RC2 client and it appears to have installed and is working correctly on windows XP.

    We have a fair number of companies who still have XP machines out there and it would be nice to see that work again. Hard upgrade sell when we need to tell them to upgrade there computers as well :)

    September 4, 2013 at 6:39 pm
    • @Tucker – Well we mentioned in the release that it now works on XP. We made a workaround to get it working. But so you know, XP testing is not being made. So if there are bugs, they will be put in very low priority. If you have XP (which is old) then you need to use 3CXPhone (the old one). You cannot expect to use latest technology with old hardware. If you have customers with XP, then they need to use applciations designed for XP.

    @Tucker – Microsoft are ending support for XP in April. Perhaps these users will need to upgrade after all….

    I’ve played around with your tips. But I’m still not able to see the group with users, with being member of that group.
    I understand that I can see the users in the default group. But I loose the “structure”. I’ve divided my extensions in 4 groups, and I want to see the users in these groups.
    Maybe a new option on the extension details (“3CXPhone” or “rights”): “extension can see all different groups”.

    September 5, 2013 at 12:35 am
    • @Filip – Contact me via email, we make a teamviewer session and i will show you. The rights and groups are perfect as they are. We have closed all user requests in this release completely.
      Each group has roles and rights. You can configure and even overrids different users to have user or manager rights and also different rights for the group. If you want contact me via email and I will show you.
      1 thing you need to keep in mind – This divisionis strictly by groups. So if you want to have a person in all groups, (just like you do in windows or in sharing, ) then you need to add that person to all the groups.

    dose anyone know if 3CX Phone System 12 RC 2 is strong enough to go into a live production environment?

    September 6, 2013 at 12:15 am
    • @sam – Release candidate
      A release candidate (RC) is a version with potential to be a final product, which is ready to release unless significant bugs emerge. In this stage of product stabilization, all product features have been designed, coded and tested through one or more beta cycles with no known showstopper-class bug.

      SO Yes – you should go ahead and put it in your production environment.

    Just wondering if a 3CX Mac OSX Client Software is available yet?

    September 9, 2013 at 4:57 am
    • @Clayton – MAC client coming soon.

      September 9, 2013 at 9:22 am
  12. Following comments from a previous thread, can you confirm whether Video capability will be added to the 3CXPhone software before the final release? Do you have a roadmap/change log available for the software to show what changes are planned and what changes have been made?

    I don’t think i’ll be upgrading our system to version 12 as it seems that our 50 mac users will no longer have access to the replacement for 3CX MyPhone as it seems that it’s only a windows native application in version 12. We also have a growing number of Chromebook users who don’t have access to the functionality included in the desktop application. It seems that the way to go for the future would be an HTML5 web application that can run on all platforms. It’s no longer a Windows / Exchange only world out there.

      Hi Joseph,

      We are taking the matter into consideration and we are working on it. If you have any further inquiries please feel free to let us know
