I'm trying to set up 3 new Yealink T42S phones with the latest firmware in an office using stun with 3cx/PIAF on an OVH vps.
The WAN has a static IP from Spectrum Business;
The router is a NetGear R8000P providing phones and switches with static IPs;
The switch is a NetGear M4100-D12G where I've tried the built-in Auto-Voice vLAN and manually built a voice vLAN with no joy from either approach.
SIP ALG is disabled;
SIP ports (incremented) are forwarded;
RTP port ranges are forwarded
Prior to setting up the phones in 3cx, IPs are assigned exactly as expected for everything in the office, including the phones.
However, when the phone is reset and tries to provision, the network connection is lost.
I've eliminated the phone, the cabling, the physical ports on the switch.
Any suggestions would be most appreciated.
