有些members,如果用电脑,可以用Skype,MSN,QQ都可以通话,那么用VoIP通话有什么优势。我可以跟大家说,如果你不用电脑,你怎样可以用MSN,QQ,Skype呢?VoIP中SIP可以让你用hardware ip phone,两边也可以通话,非常方便。不过大家先熟悉用software ip phone(Zoiper),学好了,再用hard sip phone去实现,那么简单的VoIP就可以实现了。再想想,80岁的公公婆婆和三岁的小孩都能用的系统(当然不能叫他们用电脑才能通话)。
For WM mobile phone, I found Zoiper is very good. It is in beta version but works very well in WM Professional. But if you put it in WM Standard, there is a lot background noise.
