We are in a need of a customization of the opensource VoIP / SIP client LinPhone.
The development has to be done in two phases:
Phase 1: Customization of mobile + tablet apps (iOS + Android)
// Objective C = iOS + Java = Android --> ready in two weeks.
Phase 2: Customization of PC apps (Windows, Mac OSX and Linux)
// Qt/QML = Windows, Mac OSX and Linux --> ready in four weeks.
The main customization's must be:
- Upgrade security
Many security features, which include i.e.:
--> Use TLS connectivity for handshake
--> Use VPN connection for additional security
--> Use ZRTP encryption protocol on VoIP (voice and video) communication
--> Use text encryption for messaging and file sending
--> Database security on app and server
--> Secure connection settings
--> Use code obfuscation protection + Sign the app
--> Harden the security of application / program
--+ Encrypt the entire application
--+ Containerize the entire application
--+ Encrypt the database
--+ Lock screen / Login protection
--+ Brute force protection
--+ Code hardening by Pro+iX Guard
--+ Store encryption keys securely in Trusty
--> Set privacy settings
- Design customization
Many security features, which include i.e.:
All designs are based upon the operation of LinPhone, almost no real custom development.
--> Add a lock screen / login screen prior using app
--> Every function in the LinPhone app is customized by designer
--> APP settings are blocked for users to change - one setting fits all
--> Custom user account settings
SIP server will be setup by an other person if this isn't your specialty to save time and costs.
Budget $750 - $1000 for entire project.
Ready in 2 - 4 weeks (divided in two phases)
