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?
