You're probably biting off more than you'll really want to chew with learning Arduino on a project like this.
Ring signal is 90VAC - 20Hz, which might be a bit tricky for you to detect without interfering with the line. I'd probably use a canned package for that. TI makes one (TCM1520A), but it's SMD. Want to learn soldering on a $12 IC?
Also, radios are a bit of a dark art. I'd probably do this with NRF24l01 radios (get the ones with external antennas, it's worth it if you want range beyond 50cm!), but expect to have to do a lot of screwing around to get them talking reliably.
Are you sure you wouldn't rather just buy some and put them where the phone jacks are?
Presented as a useful gadget: Krown Phone Flasher. While I hear perfectly fine out of one ear but when I am sleeping or wearing headphones my good ear is covered - so I just bought Krown Phone Flasher (LED) from Amazon for under $25 dollars. Also - does anyone know if this can be hooked up to speakers? It may help gamers see visual clues to sound cues in games?
