A friend dropped off a handful of these phones to me. Bit of a cheap build but they do have a decent screen. Did some googling and number one complaint is they are locked. Fortunately not very well. You can telnet to the phone and log in as root, no password. Change to the /tmp directory and there is a file called tmp_config.conf. In that file is the admin and reset passwords. I did a factory reset and then entered the sip settings for the piaf server. Root login does get changed to root, pw of root. Connects to the server, I can receive calls and talk away. If I try to dial out the phone appears to freeze but I can still telnet in. It never makes contact with the piaf box to dial out. Anyone else played with these? Any ideas as to why it wont contact the server to dial out?
