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
