We are interested in having an application developed for all mobiles. An application like WhatsApp but allowing to make FREE calls using internet connection.
It is an application more similar like Viber. Viber only works on some mobiles and needs 3G or WIFI to operate. We want an application to work on all mobiles and connect using edge, wifi, 3g, gprs etc.
We already have our own voipswitch and server for the completion of calls.
Please let us know if you are able to assist us in this regard.
