The call originated from a house in Menasha, Wisc. which is in Winnebago County. The person requesting the ambulance was a Vonage subscriber. However, the call was routed to the 911 dispatch center in neighboring Door County.
After researching the issue, Vonage spokesperson Brooke Schulz offered an explanation for WBAY-TV's Jason Zimmermann.
"We determined last night that the call was misrouted due to a technical issue in the trunking system, not because the customer typed in the wrong address (or a provisioning error on the address side). It turns out that SBC (now AT&T) made a translation error last week in assigning the numbers we use to route our calls to Winnebago to route the calls to Door. ...There are many different elements of the 911 system that we rely on, but do not control.""The calls will not be routed incorrectly.
"We are routing all calls from that area to our national call center while SBC is fixing the translation error," Schulz said
