[SR-Users] base64 transformation

Hi guys Maybe I missed something, but looks like there is no base64 encode/decode transformation in PV, right? I think we're going to add one, as it might be handy to do such transformations directly from within the config file. One case where this could be used is that some UAs are picky in regards to URIs as URI params, e.g. P-Foo: <sip:alice@example.org;x='sip:1.2.3.4:1234'> which could be changed into P-Foo: <sip:alice@example.org;x=c2lwOjEuMi4zLjQ6MTIzNAo=> which might be understood more easily (although it's still just a work-around for broken UAs, but that's how life is). Any objections against such a transformation? Andreas
