Call Disconnects when answering Skype Call from Extension

[enationnet]

Hello there.

I have:
3CX Phone System Version: 9.0
3CX Skype gateway version: 2.0.9919.0
HW phone: GrandStream GXP-2000

I have skype gateway configured with my skype account. [master]
When I receive a Skype 2 Skype Call, my HW phone rings. But when I lift up the receiver, the call disconnects.
I have no clue on whats happening here.
Do I need t open any ports in my Firewall? I have a LinkSys router with DD-WRT. VOIP traffic is prioritized.

Much appreciated. Please HELP!
