• OpenBTS is a software-based GSM access point, allowing standard GSM-compatible mobile phones to make telephone calls without using existing telecommunication providers' networks. OpenBTS is notable for being the first free software implementation of the industry-standard GSM protocol stack.
• The GSM Software Project: We want to bring together all the folks that are interested in building a gsm receiver.

The Pioneer Village complex comprises 28 buildings on 20 acres housing over 50,000 irreplaceable items of historical value, restored to operating order, arranged in groups and also in the chronological order of their development.

There are 12 historic buildings around the circular "green". There's a Frontier Fort, a real honest-to-goodness Pony Express Station, an Iron Horse, and a home made of sod. There's a general store and a toy store, chock full of all the goods from yesteryear. An original art collection including 25 Currier and Ives prints, 23 Jackson paintings, and the largest single collection of Rogers statues.

You can ride a priceless steam carousel, see 17 historic flying machines and marvel at 100 antique tractors. See the world's oldest Buick, a 1902 Cadillac and a 1903 Ford, both designed by Henry Ford, plus 350 other antique cars, all displayed in their order of development.

This is what Richard uses.

Practical talk based on actually running a business supplying Asterisk-based PBXs to small and medium sized businesses (SMBs). *They* don't care that it's open source.

"records all your incoming and outgoing phone calls. It can start and stop automatically, recording each phone call by its own. You will need a phone hardware, either a regular voice modem or the RecOnBox. Full automatic recording requires the RecOnBox."

"When ADSL and PSTN work at the same line at the same time, the electronics inside a normal telephone can be problem for high frequency ADSL signals: the ADSL signals can be attenuated (high capacitance on telephone input, possible resonances inside telephone, impedance mismatch) and ADSL signals can be heard as noise on some telephones (phone electronics demodulates high frequency signal outside it's operating range to voice frequency noise). In order to keep these systems apart and stop them interfering with each other it is necessary to separate the two components from the telephone line in your home. This is where the Filter / Splitter comes in. The ADSL POTS Splitter / filter allows taking the full advantage of the 1.1MHz copper line frequency spectrum, by stopping the telephone and ADSL systems from interfering with each other. An ADSL filter is normally a small plastic box with a short lead that plugs into your phone socket and two outputs, one for your ADSL Modem and another for a telephone. Some filters have only one telephone output in them. ADSL filter select the band of frequencies for each of the outputs, phone or ADSL, and send just the correct band to the appropriate socket. The phone output gets only telephone frequencies (from DC to 3.4 kHz) and the ADSL output gets the higher freuquencies well (above 25 kHz). "
