I am trying to change/re-write From URI username and From display name (*$fU and **$fn respectively) to avposp values*I tried: $fU = $avp(s:somevariable); avp_write("$fU","$avp(s:somevariable)"); append_hf("From-username: $avp(s:somevariable)\r\n"); but none of them works, any ideas on how to re-write those variables in SIP messages? Thank you* *
