Hello... 911?

Something happened to AT&T's system hardware close to work and our phone lines, in addition to everyone within a few blocks, was out of commission. Since we have an IP-based Cisco phone system, we were able to route outgoing calls to our Texas office. However, any 911 emergency calls are also routed. This was the email from our Director of Security:

Due to routing our external calling through our Texas site, 911 calls from desk phones are connecting to McGregor Police. This can cause a delay in emergency response.
