Hybrid SIM and SIP Mobile Dialer Application
Pain Points (Public)
Enterprises and remote teams often need to juggle carrier cellular calls and private VoIP trunks, but standard phone dialers cannot bridge both protocols, leading to fragmented call histories and unreliable incoming call routing across mobile platforms.
Suggested Approach (Public)
Build a unified iOS and Android dialer integrating a native SIP stack (such as PJSIP) with system telephony APIs, leveraging iOS CallKit and Android ConnectionService to handle background push wakeups, seamless audio routing, and unified switching between cellular and VoIP networks.
