Hallo,
habe diesen Threat noch nicht rückwärts gelesen, wir haben noch 15.5.15502 (mit windows 10)
und auch ALL-IP SIP Trunk Telekom aber kein Brief bekommen.
Soweit ich weiß kann deshalb aktuell nichts schlimmes passieren.
Im aktuellen 3cx Newsletter stand dieser Beitrag hinsichtlich "3cx Zertifikat"
Scheint mir nur wichtig zu sein, wenn man 3cx Webclient oder Smartphone-App von ausserhalb/innerhalb verwendet.
Auszug: In case you missed it the first time round, here is an important reminder:
3CX will be updating the SSL certificates which are required to activate the PBX, and allow secure connections between your installation and our cloud services. These certificates expire every 2 years and are due to be replaced on the 15th September.
In order to ensure uninterrupted use of your 3CX, an update (v15.5.6a) is available for install. Apply this update before the 15th September to ensure you are able to (re-)activate and refresh license key(s) information.
V15.5 has reached end of life: As of 1st July 2020, this version is now unsupported, meaning there will no longer be updates available. By upgrading to
v16 Update 6 you ensure ongoing maintenance of the product going forward.
