I get a socket engine error when I run the Chipflip example on my machine. I have the server running as well as two emulators running with different IP's. I have managed to connect both the clients to the server emulator. They get registered with the server properly. When I try to start a session, I also get the ACK packet from the other cleint, and then I get a socket engine error.

The error number I get is :
Socket Engine:
Socket error:
SIP Engine:
SIP error:

On the other client, it still shows

200 received,
Ack sent...

Plz advice.
