Sorry, missed that you were using Asterisk now. But the first issue to
address is getting multitasking working on its own, and verifying that
the app is waking up every 10 minutes to re-register.
One more quick note about Xcode and app suspend: you need to lock the
screen after hitting the home button, in order to fully suspend the
app.
In the application delegate, here's how the sample app registers the
10 minute callback:
#define KEEP_ALIVE_INTERVAL 600
- (void)applicationDidEnterBackground:(UIApplication *)application
{
? ?[app performSelectorOnMainThread:@selector(keepAlive)
withObject:nil waitUntilDone:YES];
? ?[application setKeepAliveTimeout:KEEP_ALIVE_INTERVAL handler: ^{
? ?[app performSelectorOnMainThread:@selector(keepAlive)
withObject:nil waitUntilDone:YES];
? ?}];
}
- (void)keepAlive {
NSlog(@"WAKE from sleep called");
? ?if (!pj_thread_is_registered())
? ?{
? ?pj_thread_register("ipjsua", a_thread_desc, &a_thread);
? ?}
? ?pjsua_acc_set_registration(0, PJ_TRUE); //actually sends the
registration update
}
So the main tasks, in order, are:
- make sure the app is suspending
- make sure the app is waking up to re-register every 10 minutes
And then:
- make sure the sip socket is receiving calls while in the background,
and that iOS is waking up the app when this happens
