thank you Juha, I understand the purpose and that is how I intend to use it, [more weights
for gws with more capacity]
but I guess I should have rephrase my question as: what is the purpose of the
"randomized" weight value then? when you randomize it then the weight parameter
becomes useless.
example:
3 gws inside same group, and assuming the higher the weight the higher the capacity
gw 1 with weight 20
gw 2 with weight 30
gw 3 with weight 60
I would like to send more calls to gw 3, then gw 2 then gw 1
but if when I do a load_gws, and I randomize the weight (meaning I get a random value out
of the possible 20, 30 and 60, then pick the gw with that random value, for example rand()
returns 20, then I really obtain gw 2) then there is no guarantee that the order would be
like I want it.
At least that is how I understand the "randomize" factor on this logic, do I
get it wrong? If so please advise.
txs a lot

Thanks Juha, I figured that the avp reordering would be something like that.
The help file for versions 3.1 and 3.2 also says "randomized weight", does it
really work on those versions?
this is from 3.2
***********************
When the function load_gws() is called, matching gateways (that are not currently
designated as defunct) are ordered for forwarding purposes as follows:
* (1) according to longest user part match
* (2) according to tuple's priority
* (3) according to tuple's randomized weight
**********************
or do you mean the "priority" column on the "lcr_rule_target" table
instead?
This may be a dumb question but since I don't get it I have to ask: what is the
purpose of the weight value then?
thank you

Hello
On kamailio 1.5.2, I need to choose the gw from a group according to its weight. After
trying unsuccessfully with different values I realized that the help guide says that the
load_gw functions can return gateways according to "gateway's randomized weight
within its
group". So, I have these questions:
1- since it is "randomized", does this mean that the weight parameter actually
can not guarantee that the weight value can decide how gateways are ordered?
2- once I have the gws on the avp, is it posible to re-order them? if so, how?
thank you very much
