for people who want to do something like this, not a cellphone but an actual desk phone, you can do it a lot cheaper if you want a rotary phone connected to modern phone networks. there's various oldschool bell system type desk rotary phones on ebay for $35-60 and then add a pulse dial/rotary compatible ATA ($25-55) to speak SIP to asterisk or other standards-compliant voip systems. typically this will have a 100BaseTX ethernet interface. the rest is just ordinary voip phone setup, assuming you have an asterisk or similar system to talk to, main limitation is the rotary phone obviously can't send DTMF tones. http://www.classicrotaryphones.com/forum/index.php?topic=20386.0 http://www.classicrotaryphones.com/forum/index.php?topic=203... https://www.google.com/search?client=firefox-b-1-d&q=pulse+dial+SIP+ATA https://www.google.com/search?client=firefox-b-1-d&q=pulse+d...
