"We have got to make the transition quickly because the longer we stay in this transitional state with one foot in the landline world and one foot in the IP, or internet, world the more vulnerable we're going to be", said Trey Forgety, director of government affairs for the National Emergency Number Association. "I looked at it in 2012 closely and asked for us to staff this up". They'll also add a dozen call takers a day until the issues are resolved. The Mayor says the situation improved Friday.
But officials said Thursday that it was actually abandoned 911 calls that were a source of the problem.
This has become a recurring problem.
The trouble appeared to be connected to T-Mobile phones, but neither city officials nor T-Mobile executives have offered a clear explanation of exactly what has happened.
In another incident, Deanna Cook was killed by her husband August 17, 2012, as she called 911 for help. It's a stressful job.
T-Mobile did not respond to a CNN request for comment. On Wednesday, engineers for T-Mobile traveled to Dallas for the first time in an effort to identify the cause of the problems that city officials said have been plaguing the Dallas public-safety answering point (PSAP) since November. Retweets and reposts by others would automatically generate more calls, inundating 911 centers in many parts of the country. And so when those folks hung up, algorithmically, this went insane.
He said a new national perspective must take root.
On the other hand, 911 operators tried to return each of those calls but they didn't manage to reach the babysitter.
"It's not about me", she said. In the past, not much could be done to impede 911 service. "We'll see how we get through Saturday night".

Liverpool's Juergen Klopp rued missed chances but agreed that a draw was a fair end to an eventful encounter. He said: "I never came here and said we are going to win one title".
A number of reports have indicated the 911 call centers in Dallas were hit by a spike in calls from T-Mobile that overwhelmed their systems and making it hard for callers to connect with the help they need.
On March 6, 52-year-old Brian Cross died after his husband waited 20 minutes on hold with 911. The final time, Alex says the babysitter was on hold for 31 minutes.
"She was on hold while my son was dying", she said. "Ghost calls happen when a person's phone makes repeated calls to 911, unbeknownst to the person".
Dallas Police and Child Protective Services are investigating the death, and the Collin County Medical Examiner says it may take weeks to determine a cause of death.
This week, to ensure that calls are being answered, the city is increasing staffing levels at its 911 center and authorizing overtime shifts.
Dallas Police Deputy Chief Jesse Reyes says they have a system in place for the next few days.
During the average weekend night, Reyes there are about 2,800 911 calls. Call backs to those phones show that the phones were repeatedly calling 9-1-1 on their own after the TMOB customer opened a TWEET.
A spokesperson for the FCC said the federal agency is aware of the issue and that "its review is ongoing". "It was something out of a movie".
