OK, so I guess nobody answered because we had an old version. Well, we
upgraded to 1.8.13.1 and we have much the same problem although after
the upgrade I don't seem to find any cases where the qualify value is
OK (xx ms) and the IP is gone (like we had in 1.4.29) but the effect
is the same: the extension becomes non-reachable pretty quickly.

IMHO this is indicating that the qualify settings are being ignored,
and the only workaround has been lowering the re-register time to
sometimes as low as 3 seconds. Even though several docs say that the
qualify values can also act as a keep alive, it's not working for us
and I still have to reduce the register time to very low values
because qualifyfreqok and qualifyfreqnotok don't see to be doing
anything...

Any clues??
