An Update On Asterisk
This is just a quick blog entry to note that I now have a working environment of a local telephone system, including three telephones inside the house and two located with my daughter some way away.
I initially purchased a linksys spa3102 as the first attempt to get ordinary telephones to work with , but after that I discovered the linksys pap2t, which gives two analogue phone circuits each. The whole setup works fine.
I have even managed to get asterisk to set up conference rooms and voicemail. Quality is really good.
