[Question] Android WiFi -> 3g #194

Closed ktiniatros closed 4 years ago

ktiniatros commented 4 years ago

On Android, when you switch from WiFi to 3g and vice versa, the tcp socket closes (which makes sense since you get a new ip address).

What's the proper way of handling this scenario with jain-sip? Should I restart the sipstack?

ktiniatros commented 4 years ago

I ended up to listen for ip changes (via the network monitor broadcast receiver) and when the current ip changes, then I recreate the listening point and the sip provider:

        sipManager.removeSipListener()
        getListeningPoints().forEach(sipStack::deleteListeningPoint)
        getSipProviders().forEach(sipStack::deleteSipProvider)
        val sipProfile = SipProfile(host)
        val listeningPoint = sipStack.createListeningPoint(sipProfile.getLocalIp(), sipProfile.getLocalPort(), sipProfile.getTransport())
        val sipProvider = sipStack.createSipProvider(listeningPoint)
        sipManager.updateSipProfile(sipProfile)
        sipManager.updateSipProvider(sipProvider)
