Hi Martin,

do not use the from uri as a string uuid to perform loading, but use it as key (username, domain): avp_db_load("$from","s:pai/$scheme0"); in 1.0.x or avp_db_load("$fu","s:pai/$scheme0"); in 1.1.x

in DB you will have to populate the username and domain fields instead of uuid.

regards, bogdan

Hi all

I am in the need for a little assistance on how to best use some data taken from a invite request, and then create an appropriate AVP.

My idea was to take the from header field,

    avp_write("$from", "$fromuri");

Then use it to extract the alias which belongs to this user, and create the AVP,

    avp_db_load("$fromuri","s:pai/$scheme0");

And then incorperate it into another AVP, in order to add a callerid, via P-Asserted-Identity,

   avp_printf("i:10","<sip:$avp(s:pai)@sip.domain.com>");
   remove_hf("P-Asserted-Identity"); #remove org. hdr
   avp_pushto("$P-Asserted-Identity/request","i:10"); # set new hdr

My question is, how do I best remove the port (eg. :5060) indication at the end of the from header field? Because the clients on a private IP range and my alias table does not carry the port numbers (eg. 88888888@sip.domain.com ).

So I need to manipulate the $fromuri, by removing the port indication, before i do the avp_db_load!

I was thinking of using the avp_subst function, but cant quite seem to get it to work.

Can anyone help me with a smart way to solve this problem?

All help greatly appreciated.

Kind regards Martin Kjeldsen
