1. WholeSwitch VoIP Call using SIP protocol over Wifi/3G connection
With the introduction of VoIP technology, the capability of making cheapest international calls is realizable. You can easily make local, long distant, and international calls by using a Wifi or 3G/Edge connection. Wholeswitch mobile dialers support wide range of speech Codecs which offer high quality voice even in low bandwidth environments. In addition, on Wholeswitch iPhone and Android dialers users can make video conference calls, no more calling card.
2. WholeSwitch Call through
An alternative way of making cheap international calls, if internet connection is not available, is to dial through access numbers (IP IVR), it is equal to calling card. Wholeswitch mobile dialer automatically connects to the predefined access number and pass the user’s PIN and then the destination number. Wholeswitch mobile dialers choose this method when the internet connection to the server is unavailable. Also a user can select this option to be used when there is no Wifi and he does not wish to use his data network (Edge or 3G) for VoIP calls. Wholeswitch mobile dialers support multiple access numbers which can be selected by the user or be chosen automatically based on the user’s location.
In the callback service the call is initiated by a Wholeswitch mobile dialer by sending an http request to the server. In response, the server dials the user’s phone number and once the connection is established, it dials the destination number. Both the destination and the source number are sent over to the server. This service is very useful when there is no access number in the current location of the user (for example when he is abroad) and the fees for internet connection are expensive. A user can choose which way of connection he prefers. Also Wholeswitch mobile dialers can choose the callback automatically if there is no internet connection and/or 3G/Edge is disabled for VoIP.
