Sj phone on windows 7 not register with asterisk


I am facing problem that is sip sj phone on windows 7 registrations with asterisk.

It register when install on xp but not register when install on windows 7



This is a problem with the soft phone or Windows. That soft phone is not commonly used. There are no diagnostics to give a clue as to how Windows is misconfigured, or what is wrong with the phone.
