CISCO DPQ3925 Modem/Router has a phone port RJ11 on the back. It has two but you can only access "Tel 1" - I plugged my phone in and there is no signal. I have broadband/phone bunder - My landline works on standard wall jacks, but I was just curios if there is a way to turn this on so I can have a phone on my desk.
Yes I know this is old technology with the NBN on the way, but I am just curios if anyone uses this phone port

Hi @robdido, sorry for the late reply and thanks for reaching out to us. The telephone line socket at the back of the modem is only applicable to VOIP service. NBN provides landline as VOIP which is when customers use this socket. Some Cable services have this option as well. If you have an ADSL connection then you cannot use this socket as your service is not VOIP.
Im on the HFC cable network. Will a voip phone work on that? I thought voip phones plugged in via rj45. This socket is an rj11 standatd phone socket
I understand. We have 2 types of phone technologies over our HFC network. We used to offer a landline technology that works off the CAU, which is connected to the side of your house and the telephone copper cables running from that, to the wall sockets in your home. This also runs without mains power, so if there's a power outage your telephone line will still work. As of, I think 6 years ago we switched to the VOIP that runs directly from the modem; however if there's a power outage the telephone line will not work. Depending on when you were connected to our HFC network, determines the way we have your telephone line connected to our network. Pete
