A VoIP app that enables users to make calls to SIP numbers directly from their mobile phone number, bridging traditional mobile telephony with SIP-based communication infrastructure.
Scope of work
- Implemented VoIP calling via PortSIP SDK
- Implemented network communication with a server through designed API
- Implemented secure credential storage using SSKeychain
- Integrated Flurry analytics
Challenges & solutions
Integrating PortSIP with iOS audio session management to handle call interruptions from the native phone app required careful AVAudioSession category configuration. The main challenge was ensuring SIP calls were properly suspended and resumed around native phone call events without audio glitches.
