Hello, It seems as if the bitwise operations in Kamailio 3.1.4 are broken? Please correct me if I am doing something wrong - however simple evaluations such as: $avp(s:my-test-bit) = 10; $avp(s:my-test-bit) = (int)$avp(s:my-test-bit) & ~ 2; Seems to result in $avp(s:my-test-bit) being equal to "2" rather than "8" Any thoughts / Suggestions / Fixes? I also wonder if this has any relation to !~ not working? Thanks for all of your help in advance! P.S. I sent this both to user list and to devel, please forgive me if they do not belong in one of the lists. Sincerely, Brandon Armstead
