You have to do hold via the server. Because the incoming call takes over the audio on the iPhone when your voip app is sent to the background (because the incoming call has forced it there) after several seconds the app is suspended by iOS.

But, as i mentioned in my email above, my implementation of the hold function plays a wav file on the receiver's end rather than using the one by the SIP-server. And once the event-block is reached, the call is put on hold and the wav file is played for a short time, then it stops on the receiver's end, and then i get the native dialler with the incoming call information on my end (the caller). Not sure what forced the wav file to stop but i suspect it is something to do with PJSIP's internal interruption handling. > > Cheers > AF > > > > > On Thu, Aug 18, 2011 at 3:51 PM, <s.marek at avm.de> wrote: > I did that from a totally different perspective: > > CTCallCenter gives you a callback-block for call events.
