[cisco-voip] SRST

[Michael Thompson]

Erik,

    The only TRUE way to simulate it is to bring down MGCP and truly enter
the DEFAULT applicaiton state (H.323 / SRST).  If all you're trying to test
is the ability to write H.323 dial peers then you can do just that.  The
problem is that unless you break MGCP, it doesn't go into fallback state
from a system perspective.  In the MGCP fallback config segment, it refers
to Application Alternate DEFAULT (differs from version to version on the
syntax).  That's the mode you go into after MGCP dies.  Once you're there,
the MGCP dial peers go down and your H.323 dial peers take over (including
your PRI local association).  That's going to be the only real way to test
if SRST is going to work.

MAKE SURE you configure the Applicaiton Alternate DEFAULT.  failure to do so
will give VERY eratic results (personal experience) and HOURS of lost bliss
banging your head against the wall.

my 2 pennies.
