This you definitely couldn't do, becuase that's basically like having two accounts but only paying for one.
As for having two connected to the same household (same IP address), that might be possible, but with the dual jack PAP2 I'm not sure how/why you'd need this. Even without a dual jack, you could just drop a phone line splitter on there to connect multiple phones, or simply get a cordless phone with multiple handsets.
I guess my question is simply why would you want/need an expensive SIP phone when the ATA will easily accomodate multiple (cheaper) standard and/or cordless phones.
I'm not accusing you of anything, but it sounds like you simply want to have two accounts for the price of one. However, there could very well be something I'm overlooking (and knowing me, it's a distinct possibility).
