I agree with your assessment. I will certainly have him do
that. That said, I believe that a static IP will still solve
the problem (albeit not "correctly"), because the receiving
audio continues to work, so as long as the one side is
finding the other, even though the session may be
disconnected and restarted, a static IP will still be found
correctly on the new session.

See above, I am sure you are both correct.

Thanks!

    Replying to my own post (and my most recent follow-up). I have now
    confirmed 100% that the DSL modem gets a _new_ IP address every time his
    "real" phone gets answered, or hung up! This (of course) disrupts the
    audio coming from to him, since the sending machine (Asterisk in my
    case), no longer has the correct IP address to send to him.

    I lowered his registration from the default 1 hour to 1 minute, so after
    we're disconnected, I can see that he's re-registering with a new IP
    address, each and every time :-(.

    I told him to call Bellsouth and ask about a Static IP address, but I
    don't know if they offer it, or how much they charge.

    While this one isn't "solved", it's at least "explained".

    Thanks to everyone who responded!
