3CX SBC (Session Border Controller) New Update Available

New update to the 3CX Session Border Controller available for downloadFollowing the recent release of 3CX Version 15 it was only natural that an update of the 3CX SBC (Session Border Controller) would follow. The 3CX SBC is a tunnel included in 3CX Phone System which makes the bridging of remote offices and extensions much easier. This new update includes a major improvement to the audio quality of your remote extensions.

We’ve also added a new multi threading feature that will not only improve the performance of phones connected to the SBC but it will also allow a larger number of phones to be connected.

The 3CX SBC is available for Windows only at this point. This release also includes the following

  • Major improvement to audio quality
  • Added multi threading feature
  • RTP via UDP to reduce jitter
  • When public IP of SBC changes, the SBC is automatically updated
  • Improved encryption
  • Fixed automatic re-connection bug
  • Installation UI update

    Is the new SBC only compatible with v15 (seems like an obvious question, but I don’t see it addressed anywhere)? If backwards compatible, how far back?

    • @Scott Yes of course – 3CXSBC15 works best with PBX15. It is also backward compatible with V14 but some fixes related to Audio improvement will not be present because they are made server side inside v15.

    It was discussed in the v15 launch that details about the Windows micro PCs would be posted. Under $100, including the windows license. When can we expect details on this?

    • @Ryan We are working on it. Give us some time please – we announced this just last week.
      In the meantime, if you really cannot wait, use Google and try and get as much information as you can on your own.
