[j-nsp] SRX with Avaya IP Office

[Skeeve Stevens]

Hey Dan,

So if you want to support 20 simultaneous calls you'd need 40 port
forwards?

I'm not a VoIP guy... is that just the way Avaya works? or could I setup
something else... like an Asterix/Freeswitch box with a SIP trunk to the
Avaya and do less port forwards?
