[sr-dev] uac_redirect regular expression in variables

Hello, we would like to use functions like: set_deny_filter, set_accept_filter in uac_redirect module but using a pseudo variable as input parameter. I think on several approaches: a) editing setf_fixup function, and use a trick like: if first character is '$' and second is different from '$', we know it is a variable. If first character is not '$' then it is a regular expression still not compiled. If first two characters are '$$' then it means a regular expression and escapes '$' character. b) create two new functions which accept variables. e.g: set_accept_filter_v and set_deny_filter_v The goal is to accept or deny depending on incoming provider. If speed performance penalty would be too high, may be using a hash table of precompiled regular expressions would be a good idea? Which approach do you recommend me from the community point of view?
