Say I have a record in the table usr_preferences with username, attribute=function, value=voicemail. I use avp_db_load("$from/username", "s:function") to get the value. I can print out the value in xlog function by using $avp(s:function). How can I put that value in the header by using append_hf? As I found that it doens't work if I use append_hf("P-hint: $avp(s:function)\r\n"). In other words, how can I get back the value of the variable stored in avp for other functions processing?
