Thank you, bully.

We have found 2 ways.
One is to compress the music to 8 bit x 8 kHZ, so the total music is about 125 seconds. Uplaod it, point 22-14-02 to this message, it works.

The other way is what you said, a blank message to 22-14-02, and set MOH/BGM as the internal music in 22-14-06. So after a short silence, it goes to MOH/BGM.

Thank you again for your reply.
