В ael максросы не макросы. Вызов "макроса"
&macros();
что равнозначно в conf Gosub
Значит и в Dial вызываем тот же Gosub

U(x[^arg[^...]]):
        x - Name of the subroutine to execute via Gosub
        arg - Arguments for the Gosub routine
    Execute via Gosub the routine <x> for the *called* channel before
    connecting to the calling channel. Arguments can be specified to the Gosub
    using '^' as a delimiter. The Gosub routine can set the variable ${GO
    SUB_RESULT} to specify the following actions after the Gosub returns.
        ${GOSUB_RESULT}:
            ABORT: Hangup both legs of the call.
            CONGESTION: Behave as if line congestion was
            encountered.
            BUSY: Behave as if a busy signal was encountered.
            CONTINUE: Hangup the called party and allow the
            calling party to continue dialplan execution at the next priority.
            GOTO:[[<context>^]<exten>^]<priority>: Transfer the
            call to the specified destination.
