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.

Thank you in advance for any assistance!
