Dear all Unifi expert,
Finally, I have just installed Unifi.
However, I want to connect another telephone line to the Unifi but it will be in another room.
From what I see on the current connection, my telephone line is connected to the VoIP port on the VDSL modem.
Can I connect another modem or another VDSL modem in the other room to this current TM given VDSL modem model ZTE ZXDSL931DII in the Living Hall so that I can connect another telephone to the VoIP port in the other mentioned above modem or another VDSL modem in the other room so that I can use normal telephone to make free calls???
By the way, I plan to connect both modem in different room using HomePlug. Which HomePlug in the market is the BEST?
Is there any modem available in the market with VoIP port and LAN port in a same device?
Can I setup like the one below or any recommendation?

Looking forward to your reply.
Thanks.
Your second phone also cannot. Just get a twin cordless phone set.
