Is iOS webrtc communication based on webview stable when app is background

Is iOS WebRTC communication via WebView stable when the app is in the background?

I'm implementing SIP communication using JsSIP within a WebView. On iOS, I'm using WKWebView, but I'm concerned that its resources may be limited by the system when the app is backgrounded. Even with the VoIP background mode declared in the Info.plist file, will the system preserve sufficient resources to keep the SIP communication active?
