Basically, yes.

I set it up like this:
   application rtp {
        protocol udp;
        destination-port 10000-10042;
        description "VoIP RTP";
    }

And then permit that from internet to the server IP.
(Also junos-sip.)

I don't know if Avaya supports IAX2 trunks, but if they do, you
put a SIP box on the outside -- Asterisk or SER or whatever is
comfortable for you -- and run a single IAX2 TCP port from that
box to the Avaya.

Really, PBXen ought to be in a DMZ environment whenever
possible.
