No notification received for outgoing messages

[GoogleCodeExporter]

Added observers necessary for registration and messaging events.
I can receive notifications for incoming messages but not for outgoing messages.
Does anyone also encounter this problem?

What steps will reproduce the problem?
1. Put breakpoints/logs for each event types
2. Send message

What is the expected output? What do you see instead?
Message is received by recipient but no notification for success/failure for 
the sender.

What version of the product or source code revision are you using? On what
operating system?
iOS 7.1, iphone 4-inch 64-bit, Xcode 5.1.1
