Is Smart Hub 2 Telephone Port functionally equivalent to the Master Socket phone socket

The bet is on whether or not the bureaucratic tangle around using one of the two existing analogue lines can be unraveled. That is a rat's nest almost as bad as the wiring for the system which was originally installed by BT.

There is still the technical problem though which needs to be solved regardless. That is with a single residential line can the PABX and attachments be made to work ?

It is beginning to sound as if possibly the PABX could be plugged into the Smart Hub telephone socket if wiring between the two is available?

If wiring between the two is not possible could the BT Digital Voice Adapter be used as a bridge between the PABX and the hub? I will raise another topic on that question.

I am just another customer, I cannot give any guarantees that any specific equipment will work.

However, my opinion is that a single residential line  PABX should work when plugged into the green socket in the same way as the analogue phone socket.  Not sure how the wiring to the extensions would be achieved, presumably as now. Not entirely sure why a single residential line would need a PABX,  but I'm sure you have your reasons.

@licquoriceI realise that you are a customer - thanks for your input.

The PABX system is old but is actually quite a neat solution for door entry. Phones are on different floors. Any phone can make external telephone calls but they can all be used to speak to somebody who presses the button at the door and to open it if required. You can also make internal calls.

The alternative would be to have a separate door entry and telephone systems. The PABX was actually designed with add in cards for speaking to the door and opening the door - it is not something that has been bolted on.

If they had stopped there then there really would not be a problem.  However they put in two lines sharing the same number, which turned the whole thing into a commercial system. I suppose it was originally used for a very early version of home working.
