  4. Yealink T54W No audio on LAN between other IP Phones

    I'm fairly sure this has nothing specifically to do with the yealink phones, rather how 3cx handles IP phones in general (speculating at this point). I recently have implemented hairpin NAT for our 3cx server to avoid split-dns for LAN and WAN clients. This is working as expected so far...
