sip-router handles 6xx in the rfc way (cancels all branches on which no reply was received and stops forking). This should be equivalent to disable_6xx_block=0.
However one can override it, by simply adding branches in the failure route (the ideea being that if you add a branch in the failure route, you know what you're doing an you want forking re-enabled). If I understand correctly this is mostly equivalent to disable_6xx_block=1, at least for the voicemail scenario.
Am I correct in assuming that we don't need it, because sr handles this automatically?
see inaki's reply.
