asterisk users - Apr 2011 - How does wrandom strategy works with Queue?

Hi,

wrandom strategy for Queue says...rings random interface, but uses the
member's penalty as a weight  when calculating their metric. So a member
with penalty 0 will have a metric somewhere between 0 and 1000, and a member
with penalty 1 will have a metric between 0 and 2000, and a member with
penalty 2 will have a metric between 0 and 3000. Please note, if using this
strategy, the member penalty is not the same as when using other queue
strategies. It is ONLY used as a weight for calculating metric.

Does it mean if a member with lower penalty is available, Queue will always
send the call to that member?
what if that member ignores the call(I am using X-lite as a member phone)?
Should Queue ringback the same member or ring somebody else who has higher
penalty and available?

I tried this on Asterisk 1.8.0 and found different behaviors each time.
First case it tried ringing the same lower penalty member no matter call was
ignored or not. In another case it rang second member when lower penalty
member ignored the call.

Moreover,How does that matric get calculated and affect the behavior of
ringing the member?

Thanking you in advance...

Hi AM,

Isn't that part of the definition of "random"? If Asterisk would
behave the same each time it wouldn't be random but predictable, I
would say.

AFAIK the metric just means that you get a higher or lower chance of
being selected instead of being completely random. So instead of
picking between person A or B choices it will choose between -let's
say- 10 marbles. 3 of them are white and 7 of them are black. So black
gets a higher chance of being selected. But it does not mean a white
marble won't be selected.
