Question about Yealink Telephone VoIP 16 continued SIP SIP-T57W
Hi, I'm trying to install the phone in our office - but it doesn't turn on. I can't seem to see what I'm doing wrong. there was no power supply unit included so I tried via the ethernet cable. Would so appreciate any help
The phone can either be operated with a power supply unit or via the network with a PoE-capable switch. This is probably the problem.
Either connect to the PoE switch with an optional power supply unit PSU-5V 2A5V, 2A. or LAN cable.
