Hi Tony,
Sorry for the late reply. I just fixed the crash in
interruptionListener after pjsua is restarted (ticket #1174). Thanks
for the report.
Best regards,
Ming

>>> The callback handler is called for any network state change (that is wifi->wifi, wifi->3g wifi->no signal (and the same for all 3G states too)). So in this way when pjsua starts up again it is bound to the correctly connected network interface. Unless there is a method of telling pjsua to rebind to the active network interface that I have missed, this is the only way I have found to handle network transitions.
