[Users] Have openser make changes based on message header

[Bogdan-Andrei Iancu]

Hi Brandon,

another solution will be to store the whole from contact into an AVP:
    avp_write("$hdr(from)","i:11");
and than check it against a RE:
    if (avp_check("i:11","re/....."))

this approach should be more faster and reliable than doing a search on 
the whole request. But this is possible only in cvs head version

regards,
bogdan
