That number is from the Utah Public Service Commission.

This phone number is an "outbound only" line from the Utah Department of Commerce, Heber Wells Building.  The building is located at 160 East 300 South, Salt Lake City, UT 84114-6741.
It may also be more accurate to state that the outbound phone number is designated to the Utah Division of Occupational & Professional Licensing.

got a voicemail from the Division of Real Estate Utah.

redial is a recorded message that reports this as a non-returnable number for Utah State Government.
