[OpenSIPS-Users] Route_to_gw not pushing gw_id to the first index of avp

[Podrigal, Aron]

When accessing an avp without explicit index isn't it returning the last
index?

# first time svp_gw_id is set
is_from_gw(, i);   #  avp now has (1)

route_to_gw("gw2,gw3,gw4");
# avp now has (gw1, gw2);

if we now access the avp, we can either get explicitly the specific index,
or we get the last index which is `gw2`.
So if I'm not mistaken, then I don't understand what the problem is here?


Correct me if this is wrong.
