I am wondering if there's a way to prevent new prefixes from being created in the cc_prefix table when we import rates. Some of our providers have 100 rows, while others have 50k+. When we manipulate these, I'd like to have the shortest prefix it finds to be used. I'm not talking about LCR/LCD prefix length, but the prefixes that you can edit in Providers->Prefixes. I want to keep our rate descriptions nice and generic. I don't need to have 4k prefixes for hte Dominican Republic cell phones. I just want the 40 or so prefixes that cover all the mobile phones.
For example, we have a rate plan for fax calls that are prefixed with 777 so that they are routed out T38 trunks. This created about 45k records when we import one rate deck from a carrier. We do the same with 555 prefix for data calls, which are routed out a trunk that only supports ulaw to allow credit card machines, stamp machines, etc.
Thanks,
Carlos.
