Unified Communication suite
1. VoIP call using SIP protocol over Wifi/3G connection.
With the introduction of VoIP technology, the making of calls has become easy and cheap. You can easily make local, long distance, and international calls by using a Wifi or 3G/Edge connection. Our mobile clients support wide range of speech Codecs which offer high quality voice even in low bandwidth environments. In addition, on the iPhone and Android softphones users can make video conference calls.
2. Call through
An alternative way of making cheap international calls, if internet connection is not available, is to dial through access numbers (IP IVR). The mobile client automatically connects to the predefined access number and passes the user’s PIN and then the destination number. The mobile client chooses 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. The mobile client supports 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 the mobile client 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.
4. Additional communication functionality
- Instant messaging (SIP SIMPLE), presence
- Sending/Receiving SMS
