Re: [Serusers] avp_subst for SER + some general rantings about av pairs and lingo...

Note that this is true for SER HEAD (0.10.x). 0.9.x does not have avp_subst. In SER HEAD, a lot of new (and very powerful) avp manipulation functions were added. They are created for utilizing the new selector (@something.part[x]) and the extension of $avp adressing of av pairs. BTW, the lingo is quite technical, I feel... The @ selectors are basically pre-defined variables that can be used to address (pretty much any) parts of the SIP message and manipulate them. Avpairs (attribute-value pairs) are basically variables (string or integer) that have a variable name and a variable content. By using $variable_name you are referring to a variable with a value. This value can be collected from the SIP message, it can be manipulated and it can be put into the reply (or the message to forward). The tricky part is to understand the scope of these variables (main route, onbranch, onreply, onfailure) and what you can actually do with a message in each. g-) Luis Silva wrote:
