[OpenSIPS-Users] drouting: varios entries in 'dr_rules' with some "groupid', not possible?

[Bogdan-Andrei Iancu]

Hi Iñaki,

priority applies only to rules that overlap - this can happens only when 
time selection is used for the rules:

Ex: RULE1:  for prefix 1234, all the time,  use GW1, prio =1
      RULE2:  for prefix 1234, during weekend, use GW1, prio = 4

Here the rules will overlap during the weekend - they both match; in 
this interval, the highest priority rule will be used.

The priority mechanism is used exclusively for this case.

The module does not do any rule fallback - once a rule is match, it will 
use only the destination from the rules and it will not try to re-match 
a different rule.

Regards,
Bogdan
