I’m having a crazy issue with VLANs in the latest version of FreePBX.
We’re using Grandstream GXP 2130 phones with FreePBX 14. It’s running on a Dell R710.
When the phones are on the VLAN (eth0.20) they don’t hang up after a call completes. There are also strange issues like some calls going straight to voicemail instead of ringing the destination phone.
When the phones are NOT on the VLAN they hang up properly - all is well.
Could these issues be because I’m running on old hardware with a newer CentOS release?
The Dell has Broadcom NICs and the kernel module being used is BNX2.
I’m going back to FreePBX 13 and testing the exact same setup to confirm my suspicions but I have a strong feeling there’s something wrong with VLANs in the newest kernel with the BNX2 driver. I’ll report back with some findings tomorrow.
