GSM5212 voice VLAN killing LAN access for Yealink T42S phones
Objective - I'm trying to set up 3 T42S phones for a 3cx pbx installation on an OVH vps in STUN configuration behind a Netgear M4100-D12G switch using the Auto-Voice VLAN. The router is a Netgear R8000P configured with reserved IPs for each phone. The Problem - When any of the phones are reset for provisioning, network availability is permanently lost and can be recovered only by a hard factory reset. I isolated the problem by removing the ports used by the phones from the Auto-Voice vlan and network connectivity for the phones was restored after provisioning. I would really appreciate suggestions that would allow me to reinstate the Auto-Voice vlan feature.
