Occasionally SIP message transactions are not found when they should be. In the particular case an incoming INVITE transaction is CANCELed but the INVITE transaction cannot be found so a 481 response is returned for the CANCEL. The problematic calls have a '_' character in the Via branch parameter. The problem is in the pjproject PJ_HASH_USE_OWN_TOLOWER feature's code. The problem with the "own tolower" code is that it does not calculate the same hash value as when the pj_tolower() function is used. The "own tolower" code will erroneously modify the ASCII characters '@', '[', '\\', ']', '^', and '_'. Calls to pj_hash_calc_tolower() can use the PJ_HASH_USE_OWN_TOLOWER substitute algorithm when enabled. Calls to pj_hash_get_lower(), pj_hash_set_lower(), and pj_hash_set_np_lower() call find_entry() which never uses the PJ_HASH_USE_OWN_TOLOWER algorithm. As a result you may not be able to find a hash tabled entry because the calculated hash values would differ. * Simply disable PJ_HASH_USE_OWN_TOLOWER.
