3CX V15 SP3: Unlocks G729 Codec for Server & Clients

3CX V15 SP3: Unlocks G729 Codec for Server & ClientsThis service pack is a minor service pack that unlocks the G729 codec on the server and soon the clients (it requires a server update first). Basically, from now onward you will be able to use the G729 codec on all channels. In addition, we will soon be making updates available for the 3CX clients that will have the G729 codec built in as well. Please note that SP3 is available on Windows only at this point. A Linux update will follow soon.

Download Links and Documentation

Note: When logging into the Management Console/Settings/License, you will notice that the Number of G729 Channels will still show half, however, this does not affect the functionality. Linux update will follow soon.

    • We are working on it, we need more time. A few more months but can not give exact time frame. We can say its going to be much better though with more integration and integrated into queue

    That’s it? There’s so much more that could have been added to an update like this.

  7. Hmm, I can’t see a link to the full patch notes. Is it just the new codec?
    Also is there an update to the SBC to go with the service pack?

    November 1, 2016 at 12:03 am Reply
    • No update to SBC required. Its just the codec, which we unlocked now its was available and we didnt want to keep customers waiting until the next service pack.

  8. Good news, customer will good to know that Client could have G.729. By the way, will 3CX Client need license fee for G.729 for customer?

    • Thanks for the heads up Joe, Hannes. Re client – no, paid editions will have the license automatically included for clients as well!

  10. Does anyone know when the WebRTC and PTSN confrences will be the same item? It can really be a PITA when wanting to use web meetings but not everyone has a webcam.

    • We are working on just that. Its not a trivial thing though, but hopefully within the next few months this will be a reality

  11. Here is the link to the change log that support gave me but it doesn’t give any more details other than the codec update. But I had an issue after upgrading to SP2 where outbound calls had audio issues. Shortly after opening a ticket I was given a patch which fixed my issue. I also verified that the patch was added to SP3 by redeploying SP1, upgrading SP2, replicating the issue for outbound calls and then upgrading to SP3. The issue was resolved in SP3. Thank God for labs…. I hope you guys find this helpful

    • I realize that our service packs normally have more changes, but we are slowly trying to move to “Updates” rather than service packs. Maybe we need to change our naming. The media server was indeed updated in this “update”. In reply to your labs comment – thats an interesting concept we are indeed considering allowing users to pre test updates (i.e. release them as labs first) and roll back if necessary.

    There’s still a number of options that are missing for Generic Gateway Devices such as changing the type from Analog to any other lines such as T1, custom, etc. that was available in V14. Will this be brought back?

    November 2, 2016 at 5:37 pm Reply
    • Hi Steven, We will check this, seems to be an oversight. However i recommend against using generic devices?

    It would be nice to have ability to add extensions to queue comma separated.

  15. Hi Nick,

    Do you perhaps have an approximate date for the hotdesking functionality to be released on V15?
    I do want to update some current customers, but am unable to beacause of this missing feauture.
    Kind regards

    • Hi Maarten – We dont have a date yet but we are working on it. We are integrating it into the product – so it will not be an add on script but integrated. Realistically we need another two months or so…

    I’m trying to download SP3 (for windows) but i constantly end up with version v15.0.59381 instead of V15.0.59950 (and I have to login as a new user if i follow the links)

    • Hi Chris,
      Please note that there is no separate installer for SP3. SP3 is only available through the updates section of SP2.

    When is the Hotel module being made available..?

    • We are working on it. We could easily give you a separate install that allows integration with Fidelio / PMS systems – this works already with V15. We also have a wakeup IVR nearly ready. Both these will be available very soon, probably by end of year if not before.

      November 7, 2016 at 9:26 am
    • In the next update – before end of 2016 for sure.
