Hi Guys

Suddenly all phones behind SBC are randomly having audio problems. I have installed another SBC to test but same issues.

SBC: Debian
3CX: 15.5 SP6 Debain


Any help? Thanks

OK, I have found the issues. I disabled Time Sync on Hyper-V and it instantly stopped all my issues with calls and it's been running fine now. Thanks

Thanks for the update. Next time providing more information on the environment for which the SBC was installed on would get you better/faster answers.
