Couldn't you put two ISDN phones on the same NT though? (one B-channel each)

One way to get an NT is to rent an ISDN BRI circuit from your PTT, although
it's not portable :-)

I haven't tested one yet, but you could have a look at the Fritz!Box Fon WLAN:

This has an ISDN S0 NT interface for plugging in an ISDN phone. If you can't
plug both phones onto it, then I guess you just buy two and point them at a
convenient local SIP server. It's cheap enough to take a punt on.
