Here is the layout:

SoftPhone on WinXP @ 10.0.0.201
Asterisk on VirtualBox on this WinXP (Bridged) @ 10.0.0.211
HTC SmartPhone @ 192.118.11.112 (STUN is active)

When trying to connect via GPRS, I Can see the following symptoms:

   1. RTP from the SmartPhone (192.118.11.112) is not reaching the
   asterisk,
   2. RTP from Desktop SoftPhone to 192.118.11.112 dose not heard in the
   SmartPhone

I would add that when connecting with WiFi (same LAN) everything works fine
[thanks for the STUN tip *Angelos;-) ].
*Moreover, the signaling part works smoothly. Using WireShark as well as
looking at the softphone behavior and logs,  I see all the REGISTER, INVITE,
ACK, and others traversing over the NATs without any problem.

dose anybody coped with such or alike?
