EWT describes some ways to do load balancing on outbound trunk based on number of calls. Does someone has a good load balancing module or script to manage the load balancing on trunk usage. For instance, I have a trunk with a provider A that give me 2h of call included in the price, but every additional minutes is more expensive than my provider B. I would like to change the priority order of the trunk when the 2h limit is reached within each billing cycle. I would prefer a nice freepbx/elastix way of doing it. But I guess than an independant script with a cron job can survey the cdr and change the trunk order in an outbound route via the manager or directly in the sql database. Any pointer somewhere?
