For the emulator just enable "Hack the AoR" option to receive requests from 
your server (e.g INVITE, NOTIFY, MESSAGE, ...).
The issue is  strange as the client use "rport" which means that the 403 
response should be sent the the originating socket.

I did enable the AOR and tried, It didn't work either.
Since the android emulator uses 10.0.2.2 as its contact address, the PCSCF 
replies to that port, Which is not forwarded to Android emulator by my machine, 
But adding portforwarding doesn't help as everytime the client uses new port, 
You can see ICMP port unreachable in the traces.

I will send you the traces via email.

If you check "Hack the AoR" the client will try to discover the routable IP 
(e.g. 192.168...) using "rport".
As the 403 message is a response it should not be sent to the client's binding 
address (AoR).
Could you please send the complete trace?
