Voicemail voice message shows up as a text message SMS'ed to my phone

Every voice mail left on the phone’s default voice mail server is also sent to me as a text from the number that called me.   The subject of the text message containing the voicemail’s voice to text is “Deposited a new message”   The footer of the message is “Click here” 14699825001 to listen to the full voice message”

Does that voicemail voice to text service I am describing above provided by tmobile?

Cheers
