[SR-Users] userblacklist use avp for check_blacklist

Hello, I'm trying to use the userblacklist module to implement a global blacklist. I have a few questions about the module. Is it possible to use a avp for the check_blacklist function? If i'm correct it will only parse the request URI, but i'm rewriting the URI in a branch route to allow different formats to different destinations. Or is this only possible with the check_user_blacklist function? I also have a issue with numbers in E164 format with a leading +. I tried to escape this with a \ in the database but it will not load the entry's when i use the + in front of the number. Is the + supported by this module or should i strip it before the function and add it again afterwards? Thanks, Jan
