Customisation Security & Design of VoIP APP

We are in a need of a customization of the opensource VoIP / SIP client LinPhone or Ring or Wire (if not than Jitsi). Preferably LinPhone, but if not possible one of these.

Customization of mobile + tablet apps (iOS + Android)

// Objective C = iOS + Java = Android --> ready in two 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

Time is of essence and must be ready in 2-4 weeks.
