Hi keke
When I was reading the manual , I found something exciting , I saw words : AT+VTS

Can this smstools help dialing a phone number and play to him a mp3 or wav file on my modem server ?

If yes , any examples?

AT+VTS is used to send tones. Smstools cannot play any mp3 or .wav because there is no standard interface existing.
