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?

Hello; you can try to $_s($avp(auth_code)) . For example , i use that $rU = $_s($avp(69)$var(v));
Cheers

I tried this but the same problem occurs. It translates the integer -3 into the string ³18446744073709551613".
Does anyone have a suggestion for converting an integer into a string in Kamailio? -H

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).
