[SR-Users] Kamailio routing to different carriers based on prefix

Hi there, I'm looking for a solution to route calls based on prefix, my routing table might reach a long list of prefixs. I looked to carrierroute and it seems to be nice for this purpose but i have some doubts to how to handle correctly with carrierroute. IfI understood correctly, if I set the parameter avoid_failed_destinations to 1, can i use the same carrier id and domain on failure route to select another destination that matches the prefix? Can I have the same carrier ID with diferent domains sharing the same prefixs but mapping it to different destinations? Thank you for your help. Best regards -- José Seabra
