I want to use CallVantage with my Nokia phone. Unfortunatelly AT&T does not provide any means to use anything other than bundled TA. My goal is to reverse engineer AT&T firmware and write symbian program to emulate AT&T TA. I looked at traffic between my DWL-1120M and it appear that AT&T uses some private http-based protocol for device registration. Unfortunatelly this D-Link model doesn't seem to use linux and I have no idea how to unpack and RE it's firmware. So:

1. Can anybody with enough knowledge to send me firmware of their TA. Preferably linksys (i belive they are linux based) but others will do too, even other D-Link models.

2. Can anybody with enough knowledge sniff traffic between their TA and at&t server and provide me with logs? I do not need your user id and other private information. I need all URLs you enounter with everything after ? sign removed.

3. Is it still possible to buy AT&T TA in retail store? I think some shops used to sell them but I can't find any now.
