RE: Call manager shutdown after call is established

If the call was using intercluster trunks then the call will go down.
If the GW is MGCP the call will go down.
If the GW is H.323 then you could disable H.225 keepalive timer and the call
will stay. You also need to set two CUCM service parameters: allow peer to
preserve H.323 calls (set to true) and Allow TCP keepalives for H323 (set to
false).

> If you shutdown CM and your gateway is MGCP, the call will go down as soon
as SRST takes over. If the gateway is H323, it will stay up for about 2 mins
30 seconds. Not sure how scientific that is, but it's based on a lot of
tests
with a 2821 gateway running 12.4(15)T7 with a 6.1.2 CM box. This assumes
that
you're not running a cluster or communications between the gateway and CM
have
been severed.
