VoIP

VoIP stands for voice over internet protocol. Mean can use pc to make phone call to pc or real telephone. Especially when I’ve difficulty using IM to talk to others with the NAT problem. Therefore, need to use other external software.

skype – from creator of kazaa. The good things is able to call out thru NAT and firewall.

stanaphone – claim to be the first free telephone service. Can free call to usa, canada, uk, france, switzerland, austria, spain, hk, netherlands, germany and singapore. 100 minutes monthly, the voice transmit is about 1 ~ 2 seconds lag.

The common con of voip is the sound quality won’t be so clear.
