> When the queue calculates queue's holdtime and talktime for the queue stat, it uses wrong initial info.
> To calcaulte queue stat, it uses exponential average formula. 
> Simply, for the first value, it uses average itself.
> And since the next value it calculates using exponential average formula.
> holdtime
> - It does not consider the the first value.
> - So, every calculation assumes the first holdtime is 0.
> - Example, if the 
> talktime
> - it looks like it consider the first value.
> - But it only in the service level.
> - The talk time should consider all the call's talk time..
> =========================================================
> How to reproduce
> - Reset the queue stat
> - Make a call to queue.
> - Wait call until out of service level time.
> - Agent Call Answer
> - Hangup
> - Check the queue stat
