(Tulsa, OK) -- Enhanced emergency calling service is just a month away for Tulsa.  Of the ten governmental entities combining resources to purchase and maintain the equipment, Tulsa is the last on the list.  Construction delays at the new call center have pushed the switch-over date to October 22.  When the system is up and running, the emergency call takers will be able to locate the cell phone user who is often too upset or excited to give good directions.  The nine million dollar system is bankrolled by a 50-cent a month fee on cell phone bills.  Others already on line with E-9-1-1 are Claremore, Collinsville, Glenpool, Sand Springs, Skiatook, Jenks, Owasso, Sapulpa and Rogers County.
