Anonymous calls to calling card access number drop and result in SQL query error

Anonymous calls to calling card access numbers 16045554444 and 14162225523 get dropped due to SQL lookup error for a field 'anonymous'.

I fixed it by skipping the sql query if ani_number is 'anonymous' or 'private'
in '/opt/ASTPP/freeswitch/scripts/astpp/lib/calingcard.functions.lua'

--[[ Check DID info. Original code changed to DCI code below
function get_ani(ani_number)
local query = "SELECT * FROM ani_map WHERE number = ".. ani_number
Logger.debug("[CHECK_DID] Query :" .. query)
assert (dbh:query(query, function(u)
ani = u;
end))
return ani;
end ]]

– DCI change. Check DID info. Skip sql query if ani_number is anonymous
function get_ani(ani_number)
local ani = nil – Initialize ani variable to nil
– Check if ani_number contains alphanumeric characters to avoid SQL query execution
if ani_number == "anonymous" or ani_number == "private" or ani_number == "Unavailable" then
Logger.debug("[CHECK_DID] Skipping SQL query for ani_number: " .. ani_number)
else
local query = "SELECT * FROM ani_map WHERE number = ".. ani_number
Logger.debug("[CHECK_DID] Query :" .. query)
– Execute the SQL query only if ani_number doesn't contain special values
assert(dbh:query(query, function(u)
ani = u;
end))
end
return ani;
end – DCI end ]]
