[reSIProcate] Stale Call Timer

[Thomas Troy]

Hi,

I was recently looking at controlling how to take down a call that hasn't been answered within a reasonable time frame. One of the ways to do this is the StaleCallTimer which calls onStaleCallTimeout in the InviteSessionHandler.

However, this cannot be relied upon to give a consistent user experience because resiprocate takes the user profile setting and adds a random number of seconds (up to 120) when starting the timer. I'm just wondering what is the reasoning for this?


void
ClientInviteSession::startStaleCallTimer()
{
   InfoLog (<< toData(mState) << ": startStaleCallTimer");
   unsigned long when = mDialog.mDialogSet.getUserProfile()->getDefaultStaleCallTime();
   when += Random::getRandom() % 120;

   mDum.addTimer(DumTimeout::StaleCall,
                 when,
                 getBaseHandle(),
                 ++mStaleCallTimerSeq);
}

Regards,
Thom
