DLS Hosted PBX offers E911 using the Intrado network. Our e-911 solution has unique capabilities that, for example, address the situation in which a business has multiple locations all served by the hosted service but the business has moved a phone number from one location to another. Since 911 requires the call to be routed to the Public Safety Answering Point (PSAP) associated with the physical location, end users are responsible for calling into our support center to register their new 91 address to ensure the 911 call is routed to the correct PSAP with the correct phone number. Here’s another example that demonstrates that what we can do with IP is much better than what a business gets with a traditional PBX solution. As far as a local numbering plan, each phone will have a specific DID that does not need to be published in a public directory. In other words, only the customer’s main number needs to be published. A 3, 4, 5, or 6-digit dialing plan is available for internal PBX extension dialing, depending on your organization’s needs.
