Apparently the string representation for avps via pv framework used unsigned int. I pushed a patch to master to use signed version.

What you can do is to use $var(auth_code) instead of $avp(auth_code).

In Kamailio 4.2, I’m having problems converting an AVP integer value into a string. 

My Kamailio config stores the return code from auth_check() and outputs it.  

    $avp(auth_code) = auth_check("$fd", "subscriber", "1");

    xlog("L_NOTICE", “response = $avp(auth_code)”);


When I check the AVP against an integer, it behaves normally.  However, I cannot convert it to a string.  The return value -3 (invalid user) gets converted to the string “18446744073709551613” when outputting it.


My hunch is that Kamailio is treating the AVP as an unsigned integer (rather than a signed integer) when it converts it to a string.  If I try this with an AVP with a positive integer, it works as expected.


Can someone tell me how to convert a negative integer into a string in Kamailio?
