I am storing accounting entries in the db, and I am also inserting some custom AVP values, however I also need to store the GeoIP value that I am extracting using gip. I did try the below, but it is not working, any other ideas how I could achieve this ?

modparam("acc", "log_extra",

"src_user=$fU;src_domain=$fd;dst_ouser=$tU;dst_user=$rU;dst_domain=$rd;CountryCode=$gip(src=>cc)")

Regards
