  2. SBC Update from Debian 12 to 13 Not Detecting Current OS Version

    EDIT: I shut down the VM, took another VM snapshot, and booted up again. After boot up I ran it from my own bash env with just "sudo ./sbcdebian12to13.sh" rather than "sudo bash sbcdebian12to13.sh" and hey presto - it worked! I can't say if it was the reboot or calling the script directly but...

    Scenario: We have a customer that rents temporary space a week at a time to multiple tenants. Can we use 1 SBC across all the tenants or does each tenant have to have it's own SBC? We are looking to switch our current multi-tenant system to 3CX for this project.

  8. On prem to 3cx cloud migration- V20 and SBC woes

    As title says- I am prepping an on prem instance to move to the 3cx hosted cloud. In previous software versions, you could update the local IP to the FQDN, the provisioning method, and you could set the SBC, and push a restart. I moved several systems to the cloud this way without issue. In...

  10. 3CX SBC - Set DSCP with nftables

    I noticed in the v20 Update 7 release notes that it says, "marked RTP traffic as high priority (TOS 46) ". When I upgraded to v20 about a year ago, I was surprised that the latest SBC software doesn't set industry standard QoS markings. I got to work in nftables to mark packets with correct...

    We want some SBCs for companies with many phones, but looking at the requirements guide (https://www.3cx.com/docs/recommended-hardware-specifications-for-3cx/), I see that certain processors are recommended for 100 connected extensions. The issue is that it says “Up to 100 (10 BLFs per device)”...

    I would like to change the IP Address on eth0 of my Raspberry Pi SBC. Can I simply go into the sudo nmtui utility and make the change? Will I need to do any other configuration changes at my Hosted 3CX SBC profile screen, or any other place on the Raspberry Pi?

  15. FEATURE REQUEST - Simplifying multicast for phones behind SBC

    First off, I am aware that Multicast Paging behind an SBC is not possible without extra hardware. We have insurance mandates at our primary location that require a proper alerting system in case of an emergency. We have been using multicast with everything (200+ phones in 4 buildings)...
