[OpenSIPS-Users] drouting enhancement clairifications

[Brett Nemeroff]

Hello List,

Upon looking at the enhancements of drouting in 1.8, I'm a bit confused at
all the new options for the gwlist fields. I found this snippet on the list:

>>>>     gateways :  g1, g2, g3, g4, g5
>>>>     carriers :  c1 = g1=75,g2=25  (a premium carrier), ordering based
>>>> on weight
>>>>                 c2 = g3,g4  (a standard carrier), ordering based on
>>>> given order
>>>>     rules:   prefix= 004021 ; list = #c1,#c2,g5  - first we will try do
>>>> distribute 75/25 the traffic
>>>>                   between the gws from carrier c1 and if all fail, we

Which seems to indicate the new "weights" option can be used by
specifying a gateway_id followed by an "=<0-100>" where <0-100> is
weight.

I can't really find how this is documented anywhere. Also what gets
picked first? 0 weight? or 100 weight?

What if I just want it to try 1 gateway for each carrier and not roll
from gateway to gateway to gateway? For
example, I'd like to see where I can do something like this in the
CARRIER definition:
g1=75,g2=25


and then every time I pick that carrierid, 75% of the time g1 will get
picked, and 25% of the time g2 will be
picked. But it will never go from g1, then g2 (rather I'd like it to
proceed in my script logic so I can pick

another carrier).

Or does it already do that? If I don't specify weights, does it try
them in serial order?


Is this documented somewhere that I'm missing? The regular module docs
dont' seem to show it.

Thanks,
-Brett
