only one u disk can make a call in the world！

Walktone uses SIP (Session Initiation Protocol) as its underlying messaging protocol. SIP, in addition to being an open standard that is fast becoming the industry standard, is specifically designed to take advantage of this mixed approach. SIP is quite simply the best option and being an open standard promises that Walktone will integrate smoothly with many other applications and networks.



Walktone has two major calling functions: PC-to-PC calls and PC-to-Phone calls.
• PC-to-PC: Nothing. It is absolutely free to make PC-to-PC calls in Walktone.
• PC-to-Phone: The cost is very pretty cheap, and we can customize the suits for every need.
