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.
Yes, my understanding too.
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/
One device that keeps coming up in the Linksys SPA3102. Discontinued some years ago, but seems to have been well thought of. There's one or two on Ebay along with what looks to be Chinese knock-offs. It's difficult to find any current products that will do this - I guess nowadays people use a VOIP provider...
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.
Yes! Cheers Tim -- Next meeting: Online, Jitsi, Tuesday, 2020-06-02 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
