same here, ALG is the devil =)

I think your best solution is gona be placing this inside your DMZ, aside that ... a proxy method like the one already recommended with the sip trunk

interested in seeing how you figure this out, it will be good KB

My default is to disable it, I've found that it's caused more issues than it's solved - particularly in routed environments. Perhaps there's a use case for it when NAT's involved.

As wary as I am suggesting anything to do with ALGs, have you considered letting the SIP ALG on the SRX pin hole through the RTP sessions as needed
for each call?

That and rewriting SIP packets to account for NAT are it's main functions

Hi all,

I have an SRX at a customer which has an Avaya voip system. We require
external access for SIP softphones.

The Avaya people are asking for like 500+ ports to be opened on NAT, to
which I said no.

Does anyone here have experience with the X One system and NAT through
SRX?
