You need to either deploy a proper SBC or learn how to implement STUN. Whilst the system has a public IP address is will be constantly targeted by hacking attempts (even if it is made secure from them it will still be targeted).

Talk to the SIP line provider about what their STUN server address is or what alternate they recommend. Meanwhile the support.avaya.com site has a whole raft of application notes for configuring SIP trunks with different SIP providers.
