Hi all, Is it possible to add the current from header (%fu or $fu) or contact header as parameter of the append_hf textops function? I need to add a custom header like the following: append_hf("P-Asserted-Identity: \"Caller guy\" <%fu>); Result: ...P-Asserted-Identity: "Caller guy" &lt;123(a)10.3.23.5&gt;) There is an "append_urihf()" but it adds as prefix or suffix the R-URI address. Important, SER version 0.9.7. Regards, Claudio
