autentication, NOT registration, as they keep telling me.

we don't REGISTER, we AUTENTICATE.

and, hell! set up your SBC to be port 5060, on a DIFFERENT PUBLIC IP address, and use pfsense to xlate it.

more to come.
(but, a normal ITSP account, trying to send to port 5070, like they wanted, was intermentent, and worked sometimes, but most of the time it reverted back to 5060

I don't think AT&T will agree to change the port to anything but 5060. They have always flatly refused in the past. Not sure they use Acme packet in all of their SIP products either.

In other words your server is behind NAT supporting remote users and you state your RTP ports. You disable sipxbridge (trunking) role and the rest is just firewall work, correct?

What about authentication?

    Ready to document this and write it up.

    you got ATT? Verizon? Level3 trying to sell you enterprise SIP trunks?

    they want you to send to a different port? want to send to you on
    a different port?

    Got it nailed.

    (hint:  you don't use sipxbridge as your SBC.  they go an acme SBC
    in front of their servers.  just create an unmanaged gateway, put
    on the port you need to send to, and then in the sip
    account/gateway, use their SBC)

    I CAN'T SAY ENOUGH about the support from Level3.  they spent
    several days on this, running debugs, trying this, trying that,
    till it worked.

    More (including trying to find the right wiki to post this to) later.
