SIP Server/Call Manager Service Issue

[gjassal]

I am getting frequent alerts of my Trunks going offline and online.
From the events i see that SIP Server/Call Manager service is being started randomly.
I do not see any event for it being stopped.
This is causing all of our phones to go offline momentarily as the SBC is also under Trunks.
