iCall — iOS

SwiftUI SIP/VoIP dialer for iOS, built on PJSIP 2.17 (pjsua2) via an Objective-C++ bridge.

License

This project is released under the GNU General Public License v2 (see LICENSE). It links PJSIP, which is dual-licensed GPLv2 / commercial; this repository uses PJSIP under its GPLv2 terms, so the application as a whole is GPLv2. See NOTICE for third-party attributions.

Configuration (required before building)

Server endpoints and API keys have been removed from this public source. Provide your own values (search for REPLACE_WITH_ and example.com):

• iCall/Sip/IcallApi.swift — balance/rates/OTP API keys + mobileapi host
• iCall/Sip/GatewayClient.swift, iCall/Sip/SipEngine.swift — push gateway host
• iCall/Sip/PjsipBridge.mm — default video/MOH SIP domains
• project.yml — YOUR_APPLE_TEAM_ID

Build

# 1. Build the PJSIP xcframework (downloads PJSIP 2.17 + libvpx, ~15 min)
./build-vp9-h264-ios.sh

# 2. Generate the Xcode project and build
brew install xcodegen
xcodegen generate
open iCall.xcodeproj

Requires Xcode 15+, an Apple developer account for device builds.

Video codecs

VP8 (default) and VP9 only. H.264/OpenH264 is deliberately excluded to keep the build royalty-free.

Distribution & licensing (GPLv2)

This application is licensed under GPLv2 because it links GPLv2 PJSIP.

• Google Play (Android): GPLv2 apps are permitted on Google Play, so this app may be distributed there under GPLv2.
• Apple App Store (iOS): GPLv2 is generally regarded as incompatible with the App Store Terms of Service (which impose usage/copy restrictions that GPLv2 forbids — see the 2011 removal of VLC). Shipping a GPLv2 build on the public App Store may therefore require a different license for the binary (e.g. a PJSIP commercial license) or legal review.

This is a licensing summary, not legal advice — the distributor should confirm with counsel before any public release.
