Clark said the city is examining every reported dispatch error and that he is not aware of a case in which safety was compromised by the technical issues.
Miller said firefighters will continue to protect the public despite the technical challenges.
"No matter if it is this situation or an ice storm, our members will do everything they can to protect the citizens of Tulsa and make sure they get the job done," Miller said.
He said firefighters are frustrated by an apparent lack of accountability.
"There were six different project managers put over this implementation, and some of them just flat out didn't do their jobs," he said.
Timeline of Tulsa Fire Department dispatch issues
Late 2011/early 2012: EMSA purchases the TriTech computer-aided dispatch (CAD) system for the city of Tulsa to improve communication between EMSA and firefighters.
Fall 2012: Planned implementation of TriTech CAD system by city is delayed due to "vendor issues," city officials say.
March 2012: Implementation of TriTech system again delayed due to vendor issues.
July 31, 2013: City begins using TriTech CAD system to dispatch fire calls.
Oct. 24: Fire Department forms working group to study "CAD/incident delay" problems and other technical issues.
Nov. 1: EMSA begins a new contract with American Medical Response that includes increased response times. TFD says changes will add 40 medical calls per day for firefighters.
December-Jan. 4: In numerous emails, firefighters report errors in dispatching medical and fire calls and express concerns about public safety.
Tuesday: In an email, Fire Communications Officer Gerry Tarver says an attempt to fix the CAD problem has failed. "During the testing, TriTech advised that they are seeing some other issues that will also require some more research."
