Problems with version 2.0

[darkeagle76]

Today I updated the software to release 2.0 (android ICS on a Galaxy SII phone).
Before my voip account works rigth both from 3G networt and Wifi Network from the internet.

After update I can make and receive calls but no audio is present.
I tested all combinations of Strategy (Application, default etc) not worded.
I tested also enabling and disabling GLOBAL IP for 3G and WIFI: not worked.

I wish underline that before the upgrade from v1.8 all worked RIGHT.

If I connect the phone to the local lan where the pbx is located and modify the account to use the local address of the server ALL WORKS also with the new version.

Please let me know how I can solve the problem or how I can downgrade to the previous version.
Is very urgent.
Thank you
