WebRTC + SIP.js expert needed for Ionic (ios) application (Issue FIX)

Description: We need a talented freelancer who has prior experience in [login to view URL] + WebRTC. We have a calling application that works perfectly on android using WebRTC and SIP.js. We have used [login to view URL] ([login to view URL]) for the implementation of WebRTC which works fine on android as Chrome and Android support WebRTC. The problem is with iOS. iOS does not support WebRTC natively so there are many NATIVE wrappers that might fix the issue but our application is NOT a native application and is a Cordova/Ionic based app. So we used the recommended plugin by [login to view URL] team that is [login to view URL] Recommendation source: [login to view URL] The problem is that on iOS, we used this plugin and it registers the device with our FreeSwitch server using SIP. But as soon as the other party receives the call, the iOS app crashes. We have debugged the issue on XCode and it seems like there’s a race condition between setting the states of the call (progress/accepted/acknowledgement etc) The issue is reported here on the plugin’s issue page : [login to view URL] Before applying, make sure you can show us some work you’ve done on SIP/WebRTC on iOS. And this is an IONIC app, so the fix has to be done using the current plugin or a workaround. Do start your proposal with “abracadabra” so i may know that you’ve read the description well.
