[OpenSIPS-Users] Gateway failover special setup (t_check_status question)

[Bogdan-Andrei Iancu]

Hi Max,

Something like:

      if( (t_check_status("444") || (t_check_status("408") && 
t_local_replied("all")) ) || !goes_to_gw("1") ) {

Do failover if 444 reply or if 408 without any reply received (internal 
408).
