We want to develop a Mobile dialer which can run of Symbian, java enabled and android handsets. Likely to say that on maximum range of hand sets. It will use SIP / H323 protocols. It should be able to bypass all type filtering and blockage techniques.
It will have customiseable Header and Footer through server.
It will be customized by using opertor code.
It will use ID and Password to get login and permission to call.
All other features will be as per VOIP signaling and response.
Example: Gplex Dialer, Itel Dialer, Cool Dialer tec.
You can make an offer only for one operating system only too.
Further details if required can be asked.
