Hi everyone, I'd liked to ask a question. My Profoon PDX-1430 wont make any calls. it is only able to accept calls so when i receive a call, the caller ID is working normally. but it wont ring. but the ringer is perfectly working onlyy when i'm calling intern. so my question is, why does my phone refuse to make any outgoing calls? please help me... Martha ps. I already tried to reset the phone but it still does not make any outgoing calls
