I'm trying to develop a Xamarin softphone app using linphone-xamarin. The app runs correctly on the iOS simulator, but crashes immediately when a call is established on real devices (on answer for incoming calls, just after the initial INVITE on outgoing calls).
On Android real devices, the app gets '[libc] Access denied finding property "net.dns1"' and can't register. Looking through the archives, this problem seems to have been fixed by a later version of liblinphone than is available in linphone-xamarin. linphone-xamarin contains version 3.12.0-274-gc0e2066.
Help appreciated, including using support agreements or other financial arrangements.
