Error in mysql trigger and update

I have the next trigger:

CREATE
    TRIGGER t_call_status 
    AFTER INSERT 
    ON tblcdr FOR EACH ROW 
BEGIN

    DECLARE lastid integer;
    DECLARE nseg integer;

    SET lastid = LAST_INSERT_ID();
    SET nseg = 120;

    IF ((origen = 'ANSWERED' && destino = 'ANSWERED') && (billsec_origen >= nseg && disposition_destino >= nseg)) THEN
        update tblcdr set call_status = 3 where id = lastid;
    ELSE IF (origen = 'ANSWERED' && destino = 'ANSWERED') THEN
        update tblcdr set call_status = 2 where id = lastid;
    ELSE IF (origen = 'ANSWERED' && destino <> 'ANSWERED') THEN
        update tblcdr set call_status = 1 where id = lastid;
    ELSE IF (origen <> 'ANSWERED' && destino <> 'ANSWERED') THEN
        update tblcdr set call_status = 0 where id = lastid;
    ELSE
        update tblcdr set call_status = 0 where id = lastid;
    END IF;

END;

But, i got the next error:

1064 - You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use

near '' at line 7

How can I fix it?

Greetings.
