What is SIP phone and what is the difference between SIP phone and Web Phone ?

SIP Phone is a broadband telephone service we offer using VoIP (Voice over IP) technology. You can use any SIP (Session Initiation Protocol) compatible phone adapter or a "softphone" - a program which turns your personal computer into a powerful VoIP client or any mobile phone with software to support SIP. Web Phone is Flash-based and you use flash-enabled browser to make call. SIP Phone is SIP-based and you use SIP-enabled device or software to make call.

Why Web/SIP rate is different with different plan ?

For Web/SIP Phone, we use "Least Cost Routing (LCR)" to route a call to the carrier offering the lowest cost route to that destination. SIP Phone rates are updated weekly and subject to change without notice. For higher plan, we use preselected high quality routes from Class A providers and rates are not updated very frequently.

Why is the call rate been charged different with the rate I search online occasionally?

Our system automatically selects the least cost route to reach the number you dialed. But if this route is not currently available (which is very unlikely), then the next route will be chosen. We do the best to complete your call using the least cost route. However, you can set "Max Route" under SIP Phone to define how many time your call will be routed to the next route if one route fails. The value is from 1 to 5 and the default value is 3. Go to "Search Rate" of "SIP Phone" to check all available routes and rates before you make call to one new country or area.

What kind of devices we can use for SIP Phone services and How to setup ?

Different SIP clients (hardware SIP phones, ATAs and software ones) have different configuration screens, but all have a common set of configuration parameters. For username and password below, you can find in your page "SIP PHONE".

SIP server (or proxy, or domain)
SIP proxy (or "Outbound Proxy") leave blank
Username (or User ID) username
