Peaches,
Have CT signup at,
www.packet8.net, $20.00 per month and he can call anywhere in the usa/canada 24/7
Since he will have his own dsl, he will take his packet8 small ata adapter with him to Japan.
Hook up his dsl to a cheap linksys router or whatever, then plug his system into 1 port and his ATA into another port. 5 minute setup easy.
1 port on ata plug into router, then other you plug a regular phone cord in there that goes to a reg. phone
So have him get it, or you before he leaves, pick an area code in the usa that might be local for you, if they have one, if not Atlanta, Dallas, wherever you want.
From Japan, he just dials 1-555-1212 it doesn't know or care he's over there. He can talk 24/7, 20.00
If he can get a local # to you, then you just dial the local # and it rings in Japan.
We have 6 ata's under our company account, 2 are overseas, and you can't even tell your calling 1/2 way across the world.
When I goto europe, I just bring my home ata with me, and call home / the mrs calls me at the local #, no more cell LD calls at 1.00 per min.
If you need help, let me know.
