Continental Utility Systems Inc., the utility billing software provider for the city of Pleasanton, has confirmed that a standard test of new software services accidentally generated phone calls to some Pleasanton residents on Monday and Tuesday.
"The test was an isolated event and does not represent a data security breach," CUSI stated in a press release. "The City of Pleasanton had no prior knowledge of or involvement in this test."
A number of Pleasanton households received the calls late Monday and early Tuesday from a telephone number identified as the city of Pleasanton's. The number showing on telephones with Caller ID is 931-5425, the city's utility billing department.
Joanne Hall, public information officer, said the city's phone vendor determined that these calls are not originating from the city of Pleasanton's telephone equipment.
When CUSI became aware of the problem and corrected it, Pleasanton city staff was notified, according to the press release.
"CUSI apologizes for any inconvenience this test may have caused local residents and would like to express CUSI's continued commitment to supporting and improving the utility billing services offered by the City of Pleasanton," the release continued.
