Hi Manoj,
There is no "maximum" time that SRST can remain in effect. You hope that it isn't too long to CCM fixed, but SRST could work indefinitly. Here is a little clip from an excellent SRST Overview;
"Cisco Unified SRST overcomes this problem and ensures that the Cisco IP phones offer continuous (although minimal) service by providing call-handling support for Cisco IP phones directly from the Cisco Unified SRST router."

Hi Manoj,
You are most welcome my friend :) Luckily there is no "8 hour" type restriction. Have a look at this recent thread that does show why this (SRST) must continue to operate.
I feel for Kenneth and the people involved.
Take care,
Rob
