The provisioning port has changed to port 5000. This means that you must change the provisioning links for the phones to “http://IPADDRESSSERVER:5000/provisioning”. You can do this via DHCP option 66 or by configuring the phones from their web interface. See the configuration guides for more information. Reboot the phones after you have made this change.

3CX Desktop Components has been also updated. Click to watch Installing Desktop Components on YouTube.

  1. Upgrading 3CX Phone System RC on the server, will also include the latest 3CX Desktop Components instalation file.
  2. If you have 3CX MyPhone Installed locally on the client machines simply double-click them. You will see a silverlight message popup notification informing you that the application has been updated and needs a restart. Proceed with the restart of the 3CX MyPhone Silverlight application. Upon restart 3CX MyPhone will be updated from Beta to RC.
  3. Log in, navigate to Settings tab and click on Preferences
  4. Click on the INSTALL Button. The latest version of 3CX Desktop components will be installed locally. Double click on the installer and follow the installation instructions.
  5. Once the 3CX Desktop components have been installed, double click on 3CX MyPhone Application on your desktop. Your 3CX MyPhone application is fully updated.

    Nice job 3CX Developers. We are loading Ver. 10 RC and running with it effective immediately. Hopefully Ver. 10 will be released before the end of the month. Happy Easter to all who celebrate!

    Always apply the HTTP API of version 9?
    In Version 9 when Abyss web server is used, the links should look like the example below

  8. @Claudio – No the port has changed to 5000 now. All 3CX Websites in both IIS and ABYSS webserver installations have all their websites on port 5000. So simply change 5481 to 5000 and it will work. Thanks

    I cannot get this to work, I have a GXP 2100 with phone provisioning enable, it gets it ssettings OK from the tftp server but I get:
    SIP request (REGISTER) from was rejected. Reason: Block WAN requests is ON.
    .in the server event log and also:
    Authentication failed for SipReq: REGISTER tid=1260901722 cseq=REGISTER contact=103@ / 2017 from(wire); Reason: Credentials don’t match, check that authorization-ID and password match the ones in extension settings
    … in the server activitylog.

    Actually this is fixed by turning OFF the option in Extension > Other > Disallow use of extensuion outside the LAN. But the 3CX and the grandstream are on the same lan and subnet?

    April 26, 2011 at 4:17 pm
  11. @Brian – the 3CX and the grandstream seem to be on the same lan and subnet yes but this happens to not be a LAN. It is a WAN. From what I see it is trying to register from external location. “Block WAN requests is ON.” This happens because from what I see 89.0.9.X is not a local ip address scope. Can you confirm this pls?

    Change from Ver 9 to 10 went smoothly. Removed 9 and attempted to install 10 without a reboot. It didn’t like that as load failed saying that port 5000 was already in use. A PC reboot solved that issue. So far so good.

  14. @lee
    Did you see a message from the installer prompting you to reboot?

    May 8, 2011 at 1:23 pm
  15. Running on 10 RC2 now.
    Tested on Cisco / Polycom / GrandStream.
    Love the new email alert feature! Merci 3CX!
