    Hi all,

    We've got an issue with our Snom 760/765 phones not creating conference calls. The Snom 820/821s all seem to have no problem with this.
    The provisioning templates are virtually identical for the phones.

    I tested swapping a phone from one type to the other on my line and the issue was persistent - only the 76Xs are having the problem.

    We are using 3CX server version 12.5.44178.1002.


    Here are the log outputs from each phone type for the conference calls made:

    76Xs:
    14-Jul-2016 10:05:54.049 [CM503020]: Call(C:3067): Normal call termination. Call originator: Extn:210. Reason: Not found
    14-Jul-2016 10:05:54.049 [CM503016]: Call(C:3067): Attempt to reach <sip:mad:700**210:5060> from Extn:210 has failed. Reason: Not Found
    14-Jul-2016 10:05:54.049 [CM503014]: Call(C:3067): No known route from Extn:210 to target: <sip:mad:700**210:5060>
    14-Jul-2016 10:05:54.049 Call(C:3067): from Extn:210 to doesn't match any outbound rule. No outbound rule could be selected.

    82Xs:

    19-Jul-2016 10:53:13.752 [CM503004]: Call(C:38): Route 1: from L:38.1[Extn] to T:Conf:700@[Dev:sip:700@127.0.0.1:40300;rinstance=ee184db384047465]
    19-Jul-2016 10:53:13.751 [CM503001]: Call(C:38): Incoming call from Extn:228 to <sip:700**228@10.1.1.19:5060>


    Just hoping this is a simple fix someone might be able to clue me in on.

    Thank you in advance for any assistance!

    Just an update to this. The issue don't seem to be SNOM phone model related, but a firmware issue.

    Further testing confirms the conference function works with firmware up to 8.7.3.25 on all 800 and 700 SNOM models, but is broken for all phones running 8.7.5.x versions.

    It appears from the 3CX log the firmware 8.7.5.x is generating a different/incorrect route to the conference extension
    8.7.3.25 connects to the conference extension via <sip:700**228@10.1.1.19:5060>
    8.7.5.35 attempts to connect to the conference extension via <sip:mad:700**228:5060> giving "Not Found" on the deskphone.


    Any assistance with this is appreciated.
