Not sure where to put this but I guess it most people here would have known about this but not me.

My "Landline" is connected to the UFB (ie not via copper) when with upgraded to Spark UFB.

When I rang my landline today not knowing that the phone was not connected, I got a dial tone and it rang for about 20-30 seconds.

After doing that a few times and had no-one answer I discovered the landline phone was disconnected (cordless phone, base power off).

Thought I'd inform the public as an FYI!

VoIP is similar to as a wireless router. You can connect to it if its powered up. But that doesn't mean the WAN is active/it has anywhere for your devices to go.

If your router is online, its registered against the VoIP system and tells it it is ready to accept calls. It doesn't actually care whats plugged in (or not) behind it.

Copper was the same, the only time it really gave a respondant signal, was when the device was plugged in and completed the circuit - busy, or offhook.

Similarly, if you de-register the VoIP. But pickup the handset.. that's not a good test for 'is the phone working', Most times the router is generating false local dialtone and isn't a good indicator.

So my landline is essentially voip but straight from the ufb console and the ufb console is completing the circuit.

Yeah. It's rather complex. But goes a little something like this... (I think.. Hio77 will be more clued up)

Chrous run/are building the CCN network. And offers inbound connection points from ISPs/VoIP Providers.

Much the same way as they run the fibre to your door. Consider them, the middle man holder of records.

From there, the ISP/provider you are with creates a local configuration on their STUN server that you authenticate to.

Your router holds those details (like how ISP logins use to work), registers and the sever then has a P2P live connection to say.. here I am, ready to accept/make calls

Someone picks up their device, calls your allocated number. It queries the centralised CCN to find out if your number is analogue, or registered as VoIP. Knows who the hosting provider is of that registered number. And routes it to their external facing side of the STUN server accordingly.

Gets to ISP, hey.. we have a call for this number.

ISP goes sweet, know what connection that is registered on at present. I'll patch you through to the router.

From there, your router makes the device ringy ringy. Or if its not plugged in, not tell you at all as you have found :D

Its called an ONT (Optical Network Terminal)

Hi, the ATA is where ever, it does not care a phone is actually connected to that ATA it will still appear to ring, this is no different to analog POTS as the line interface of what ever ATA is only aware if the line is looped or not, if not it will ring it if instructed.

Also, and please someone correct me if I am wrong, when you use the ONT for voice their is no true VOIP ATA in the ONT instead a PCM time slot is extended via a voice GEM to the ONT's "line interface", that PCM time slot can be derived from some VOIP infrastructure back in the network or direct from a NEAX or other PCM switch, ie the ONT is not a full VOIP ata, as I said others may correct that understanding.

Bascially this is the same for analouge.

If you unplug the phone from the jackpoint, the caller still hears the ring and you would be none the wiser.

If you want to mitigate, then get one of those cordless phone systems that uses the main handset as a battery source for the main base station whilst enabling you to use the 2nd cordless phone as the phone during a time when your power to the main base station is off. BUT, remember if the power is out, so is your ONT so you will need some sort of battery backup for that. Some of us on here use 'constantvigil'.

cyril7 I believe you are incorrect here. This is why older monitored alarm systems, dial-up modems, health alarms, old sky decoders and other analog data services etc may not function correctly over the ATA port. The only difference between the ATA implementation on the ONT versus one done on the CPE router (as is also very common) is that the ONT ATA's has a dedicated amount of bandwidth reserved for it on Chorus' backhaul. The RSP still has to provide a full SIP compatible service to terminate the ATA 'circuit'. It most certainly does not go back to a NEAX.
