XMPP App send message with when app enter background mode

Question

I use the apns to push messages to my app, when it run in background. But APNS sometimes delay is very serious.

So how about try to set VOIP and set xmppStream.enableBackgroundingOnSocket = YES; in order to replace APNS when app run at background ？or we combine the two approaches use.

What i consider are the following points : 1.how long a app can run in background,when we set a VOIP? 2.does anyone have succeeded when use VOIP that appStore did't reject ?

ps: sorry for my English,and Here's a reference a link! THX in advance

Answer 1

You need to implement real VOIP calls to be approved with VOIP capabilities. Check the following XMPP VOIP extensions: Jingle and Jingle RTP. Another way: use SIP with XMPP, check CUSAX RFC.
