[SR-Users] Doubd about Dialplan module

Hi all, I'm tryting to implement a E164 normalizer using the dialplan module, by now I have 3 simple rules: dpid priority matchop matchex matchlen subsex replaceex attributes 0 1 1 (00|\+)([1-9][0-9]+) 0 (00|\+)([1-9][0-9]+) \2 0 1 1 ([5-9][0-9]{8}) 0 ([5-9][0-9]{8}) 34\1 The first rule 'it's supposed' to remove + or 00 from full qualified E164 numbers, the seccond rule 'should' add 34 as prefix to all 'valid' spanish numbers, they was running on some little test I did, but when try to put them on pre-production enviroment I get strage results. I call dp_translate as dp_translate("0","$rU/$rU"); And this what I get : Input RURI Output RURI 900XXXXXX(a)dom.tld XXXXXX(a)dom.tld And the quetion is why?, are my match rules wrong? why subex and matchex must be the same?
