[Serusers] how-to "loop" in the ser.cfg file

Hello: I need to perform a check several times within a failure_route and I'm not sure how to accomplish this task. The way I implemented sequentially hunting I perform the relay to the first number in the hunt list within route block 0. If this number is unavailable I "fail" to a failure block then interate through the remaining numbers in the huntlist in that failure route but this presents a problem. All of the "feature" and "call permission" checks which I normally perform on an extension are only performed in route block 0. This means I am not checking the feature and call permission flags for the 2nd through Nth number in the huntlist once I enter the failure route. I created a route block to perform the necessary checks but the problem is I do not see how to return to the failure route if the feature check for a given number fails. For example. If the t_relay to extension 1234 fails I will enter failure_route #1. In failure_route #1 I load the next extension, 2345, but if the call permission check for 2345 fails how do I skip this number in the huntlist, load the next number in the list and repeat the failure_route #1 processing? Thanks,Steve
