[reSIProcate] Timer running after registration - Is it useful?

["Yong, Chee Yeew " <Chee-Yeew.Yong@xxxxxxxxxxxxxxx>]

Hello all,

After I have completed a registration with the SER, I am finding that DUM
sets up a timer. I would like to know if someone can suggest what's the
usefulness of this timer. I attached the Debug printout (relevant item is
2nd last) below:

=============== end of debug printout =============

I am guessing that this timer is used for refreshing my registration. But,
how is it triggered?
Do I have to call DUM.process() or Stack.process()?

Thanks in advance!
