DALLAS (AP) — Dallas public safety officials are pressing T-Mobile for solutions after a 6-month-old boy died after his baby-sitter couldn't reach 911 operators.

A city statement says the 911 call center was jammed with calls Saturday because of an ongoing issue with T-Mobile. WFAA-TV of Dallas-Fort Worth reports that when a T-Mobile customer calls 911, ghost calls are created that jam the system. Operators end up putting callers on hold as they try to catch up.

Bridget Alex says she was at her sister's house after the funeral for her 19-year-old nephew when the sitter called her frantically. The sitter said 6-month-old Brandon Alex had fallen from a day bed and was unconscious. The sitter said she had called 911 three times and kept being placed on hold.
