Hi, Conversation in the virtual meeting late last night turned to establishing a PBX at home hanging off a single POTS line. Here's some related resources based on what was said and a bit of searching since.
What are FXO and FXS? A brief summary: https://en.wikipedia.org/wiki/Foreign_exchange_service_(telecommunications)#Use_in_voice-over-IP_systems More detail: https://www.dceexpress.com/what-are-fxs-and-fxo/ So I think the incoming POTS would connect to an FXO device which, `from the point of view of a telephone exchange, appears to be a telephone'. The other side of the FXO would be a digital interface to the computer, e.g. a PCI Express card. Once it's digital, VoIP phones could be used around the house with each having a unique extension number. Android and iOS devices can also run apps to be a VoIP phone; there might be lots of those already around, especially older models. A well-known telephony interface manufacturer is https://www.sangoma.com/telephony-cards/analog/ An alternative is for the existing land-line number to terminate with a VoIP supplier on the Internet and to use the home's Internet connection thereafter. A POTS does have the advantage of working in a power cut. -- Cheers, Ralph. -- Next meeting: Online, Jitsi, Tuesday, 2020-05-05 20:00 Check to whom you are replying Meetings, mailing list, IRC, ... http://dorset.lug.org.uk New thread, don't hijack: mailto:dorset@mailman.lug.org.uk
