Hi
Search on the Avaya support page for known port list it will tell you what ports to open. I would advise you though to look into the VPN hardphone if its only one phone. The VPN software resides on the phone and your set-up is more secure

try:

sip

5060 TCP and UDP
5004 UDP
10000 UDP (sipgate Stun service - usually 3478/9)
6348-32768 UDP (RTP, RTCP multimedia streaming)

h-323

1718—Gate Keeper Discovery UDP port
1719—RAS UDP port
1720—TCP Control Port
