Hello Again,

As stated in iPhone App Programming Guide Document, below are the interfaces 
that can be used to configure VOIP:
- NSInputStream and NSOutputStream
- NSURLRequest
- CFReadStreamRef and CFWriteStreamRef

I just want to clarify if the first two options can support only TCP 
connection? Or is UDP possible?
I already tried CFReadStreamRef and CFWriteStreamRef and they support TCP. I 
don't know if it is 
possible for UDP connection (for CFReadStreamRef and CFWriteStreamRef). Is it 
possible?

I need to know this since my VOIP app uses UDP connection. But I need to 
support multitasking 
feature on iOS4. Is this possible without changing its sockets UDP connection?


I really need help. T_T 


Regards,
Angie
