Hi

I have a scenario where dispatcher is used to balance calls. Assume there are 2 media servers M1 & M2. Call are routed using round robin algorithm. There is scenario where call is handed over to M1 but it is not answered in defined time period (say 5 seconds due to load on server or network congestion), I wish to send this call to M2. What are the options to achieve it?

you have to use a failure_route in this case to do re-routing. The dispatcher module readme has a sample kamailio.cfg that shows how to use such failure route:

- https://www.kamailio.org/docs/modules/stable/modules/dispatcher.html#dispatc...

You should adjust the if block before the ds_next_dst() in failure_route to match the situations when you want to do re-routing.
