Dear All,
Which port can I use for Internat phone? I am using an internet phone program with the name Ring Voiz. It's used for calling to oversea from my country. It's very cheap to make a call to cellphone or homephone in foreign. I can not do that in my office :( Because my IT admin haven't openned port to make this call. and he also don't know what port to open :( Everytime, I want to make a call to oversea, I have to make a statement the static IP which he provided me before, then I just can access to Internet directly and using Ring voiz program. I'm in Vietnam, so my english is not good. Thank you very much for understanding my english!
Best regards,
TT
