The version of WeePhone 1.4.4 is SIP software that is carrier independent and is, thus, a stand alone SIP client. The issue is that even when you set up the correct values into the settings panel for the SIP provider, the software will sometimes refuse to register with the SIP service even when it previously worked. So, it continues to say Logged in: no. This software desperately needs a login button to force registration to the phone system. Instead, when it gets into this non-registering mode, there is no way to force the software to try again. I have restarted the app as suggested and I I have even completely rebooted the Touch and it still refuses to connect. The software desperately needs a reset button to clear out the settings to start over. Whenever this non-register mode appears, theres no way to easily clear it out this condition and get the software to register with the SIP service.
