    One ATA 186 working like a champ behind a NAt on a Linksys.
    Be AWARE!!! I run into some other ATA 186b with older software that still work behind NAT, but with the same exact configuration do not give you any ringback.

    One good tip to test ATA behing NAT.
    Use the I.P. address of “Dual Talk” gateway to test.
    Dial “123” on the phone, plus the I.P. of the gateways.

    like this:

    123**xxx*ccc*ggg*ttt#

    That will send the call to the dualtalk gateway I.P. just for this call.
    You will hear an announcement. Goes trough most NATS like a bullet.

    What you are doing here is using the NAT penetration features of the DUAL Talk system; not your ATA. The 123 announcement has special NAT penetration features designed and implemented by DUAL Talk.

    No much trouble at all. Just make a static route to the I.P. that dual-talk uses, set up the numbers that you want to send to dual-talk,set up codec and you should be getting the test messages on no time.

    If you need the configuration, I still have a Quintum A400 that is out of service that still have the configuration.
