@Marvin_S can it be set indirectly via telnet and the CLI ?

@leonjackee6 can you post a screenshot of that? I am unable to find this on the emulator.

@Marvin_S the Nova isp from Greece gives the following info for VOIP to work DHCP Option 61 --> 30210χχχχχχχ_somedomain Registrar/SIP server/Sip Proxy ---> somedomain SIP number ---> 30210χχχχχχχ SIP...

@Marvin_S what about other ISPs from other countries which use dhcp option 61. Can we somehow manually enter the client id from the web interface?

Can someone from tp-link answer the question how can we declare the client Id for option 61 in TP-Link Archer VR2100v Is it possible?Can you provide a screenshot of the setting inside the web...

Can you please explain how to enable DHCP client identifier option 61 on TP-Link Archer VR2100v ? Can you please show me on the emulator? https://emulator.tp-link.com/vr2100-v1/index.htm
