[Kamailio-Users] dispatcher failover between two groups

Kam 1.5 I'm using dialplan module to return a setid for the matching regex which is passed onto dispatcher to select the proper gateways. This works fine including failover to the next gateway in the group in failure_route. What I can't quite wrap my head around is how I can setup failover between different dispatcher groups. The scenario is as follows: 2 external PSTN gateways (sip trunks) in group 1 6 internal gateways with PSTN access via PRIs. Two gateways per group for a total of three separate setids in dispatcher. I'm doing some LCR across the 6 internal gateways which are all in different cities via regex matching in dialplan. What I'd like to do is try one of the internal groups first if it matches the local NPA/NXX, and if ALL gateways in that group fail move on to the external gateway group, and try all those gateways (and vice versa in my external gateways fail for non matching numbers). I thought of two possible solutions but I'm not sure if either will work how I expect. 1) Use the priority field in dispatcher to setup a large gateway group that has all the gateways I want to use. - I tested this out in kam 1.5 and the priority field seems to be ignored when hasing on call-id. - What is the intended usage of priority? Will setting two gateways to 0 and the rest to 10 cause the load balancing functions to only select the ones with 0? It seems to be ignoring priority and using all 8 gateways 2) Once in a failure_route can I move the processing into a request_route and call ds_select_dst again with a different setid and append it as a branch? Is there a cleaner solution?
