Key Differences Between ANI and ALI Databases

V1 VoIP explains what the key differences are between the automatic number identification ANI and the automatic location identification ALI databases and their uses in voip emergency phone callsV1 VoIP is committed to offering our resellers and wholesale agents the best emergency solutions because you never want to be without in the event of an emergency. A common question asked about emergency services is what is the difference between the ALI and ANI databases and how can they effect emergency response?

Automatic Number Identification (ANI) is the automatic display at the PSAP of the telephone number associated with the line which called 911. Each telephone number and the physical location to which it corresponds are stored in an Automatic Location Identification (ALI) database, managed by the local exchange carrier.

When you call 911 the operator is looking at a screen, sees the adddress of the caller and says “help is on the way.” In that 911 call, the PSAP uses the ANI to retrieve the caller’s physical address from the ALI database. Additionally, the ANI acts as a callback number should the PSAP lose its connection to the distressed caller. Both ANI and ALI are key capabilities of E911 service.

With traditional E911 service, ALI records are stored in regional ALI databases, and are usually administered by the local exchange carrier (LEC). When a phone’s location changes, the regional ALI database must be revised with new location information which can take up to 48 hours to update.

Due to the capabilities of IP phones, it can be difficult to ensure that the regional ALI is up-to-date. Whereas traditional telephone numbers are static, IP phones can be moved easily, forcing the user to notify a network administrator, who in turn must contact the LEC to update the phone’s location in the regional ALI database. Unfortunately, this process takes time to implement, and may be forgotten entirely by the user.

Additionally, IP phones can relocate to regions served by different ALI databases entirely. A VoIP service provider or enterprise would then need agreements with each LEC to update different regional ALI databases as phones move around the country.

Ultimately, it is difficult for regional ALI databases to stay current with nomadic VoIP users, and there is no guarantee that the VoIP caller’s accurate location information will be available in a crisis.

ANI and ALI Databases for New VoIP Resellers

V1 VoIP explains the importance of automatic number identification ANI and the automatic location identification ALI databases and their uses in voip emergency phone calls

As a new V1 VoIP reseller, you are going to hear a lot about ANI and ALI databases. But as a new reseller, you may not know what they are. And they are important as they relate to your emergency telephone needs. Let V1 VoIP explain:

What is the difference between the ALI and ANI databases and how can they effect emergency response?

The Automatic Number Identification (ANI) is the automatic display at the PSAP of the telephone number associated with the line which called 911. Each telephone number and the physical location to which it corresponds are stored in an Automatic Location Identification (ALI) database, managed by the local exchange carrier.

Let’s say you are watching an episode of Fox’s drama ‘911’. The emergency operator is looking at the screen and sees the adddress of the caller and says “help is on the way.” In that 911 call, the PSAP uses the ANI to retrieve the caller’s physical address from the ALI database. Additionally, the ANI acts as a callback number should the PSAP lose its connection to the distressed caller. Both ANI and ALI are key capabilities of E911 service.

With traditional E911 service, ALI records are stored in regional ALI databases, and are usually administered by the local exchange carrier (LEC). When a phone’s location changes, the regional ALI database must be revised with new location information which can take up to 48 hours to update.

Feel Safe in an Emergency with V1 VoIP E911

E911 stands for “Enhanced 911”, which is the V1 VoIP service for making 911 calls over an Internet connection instead of over a standard wireline or cellular tower routing system. Beginning in 2005 all VoIP providers have had standard E911 capabilities included in all VoIP plans. So, even if you are not with V1 VoIP, you can be confident that you will have a reliable 911 service at all times.

Because VoIP E911 is not quite the same as regular 911 service with landline providers, 911 operators cannot automatically trace an E911 number to the physical location from which the call originated as they can with traditional 911 services. When a 911 call is made from a traditional wire landline, 911 operators are able to trace the call to the physical location from which the call originates. i.e. your home or office. When a 911 call is made from a cell phone, the cellular towers create a triangular mapping system to find the location of the caller. VoIP calls work a little differently from both of these technologies.

Many people don’t really understand the actual limitations of VoIP E911 and so have an unnecessary amount of anxiety about it. VoIP calls are not traceable to physical locations. So, when a customer gets VoIP service, they need to register their VoIP phone number with their home or office address. This way the 911 operator will be able to see what physical address the VoIP phone number is connected to.

V1 VoIP providers instruct resellers to update their customers’ registered address any time they register for service and/or move to a new address so that emergency workers don’t show up at the wrong house during an emergency. And when a VoIP customer wants to make calls through their VoIP number when they are traveling, VoIP providers recommend that the user changes their E911 registered address to the address that you are staying at, whether that is a hotel or relative’s home.

Because VoIP service depends on a reliable Internet connection, it also depends on a reliable energy source. This means that in the event of inclement weather or other power outage situations, you should be prepared with a back-up power source for your Internet connection like a battery plug-in, or a generator if you expect long periods of power outage.

Accidents may happen while you travel, or in the comfort of your own home. Emergencies can’t be predicted, but having a lifesaver just a dial away with VoIP is all the assurance that you need. No one wants to make a 911 call, but if an emergency does occur, users can feel safe with V1 VoIP E911.

ANI and ALI Database Differences

V1 VoIP answers questions about emergency information locations and the differences between ANI and ALI databases

What is the difference between the ALI and ANI databases and how can they effect emergency response?

The Automatic Number Identification (ANI) is the automatic display at the PSAP of the telephone number associated with the line which called 911. Each telephone number and the physical location to which it corresponds are stored in an Automatic Location Identification (ALI) database, managed by the local exchange carrier.

When providing phone service to either businesses or residences, customers need to know important information regarding their ability to make emergency telephone calls. V1 VoIP is committed to offering our VoIP providers, resellers and wholesale agents answers to their questions about emergency information.

Let’s say someone calls 911. The 911 operater will answer the call, look at their monitor, see the adddress of the caller and says “help is on the way.” In that 911 call, the PSAP uses the ANI to retrieve the caller’s physical address from the ALI database. Additionally, the ANI acts as a callback number should the PSAP lose its connection to the distressed caller. Both ANI and ALI are key capabilities of E911 service.

With traditional E911 service, ALI records are stored in regional ALI databases, and are usually administered by the local exchange carrier (LEC). When a phone’s location changes, the regional ALI database must be revised with new location information which can take up to 48 hours to update.

Due to the capabilities of cellular and IP phones, it can be difficult to ensure that the regional ALI is up-to-date. Whereas traditional telephone numbers are static, IP phones can be moved easily, forcing the user to notify a network administrator, who in turn must contact the LEC to update the phone’s location in the regional ALI database.

Canadian Radio Television Telecommunications Commission e911

V1 VoIP up to date Canadian Radio television and telecommunications Commission enhanced e911 requirements for VoIP service providersIf you are in Canada and using VoIP, take a moment to familiarize yourself with the requirements VoIP service providers must meet in your country as set forth by the Canadian Radio-television and Telecommunications Commission (CRTC).

The CRTC established decision 2007-44, which requires VoIP service providers to make 911 services available to their fixed/non-native and nomadic VoIP subscribers. VoIP service providers connect the IP realm and the Public Switched Telephone Network (PSTN), allowing subscribers to benefit from increased efficiency by routing calls over the Internet.

The CRTC decision obliges VoIP service providers to deliver all 911 calls to the appropriate Public Safety Answering Point (PSAP) using the zero-dialed emergency call routing service (0-ECRS), rather than PSAP low-priority lines. Adherence to this decision is mandatory for all VoIP service providers offering services in Canada, and is designed to protect the safety of VoIP users who expect that when they dial 911, they will quickly be connected to qualified emergency responders.

How VoIP IP-PBX Systems Use 911 Service

voip and IP-PBX phone systems have problems with traditional 911 service so you need E911 emergency servicesV1 VoIP knows its imperative that our resellers have the most up to date information for emergency services. Here, V1 discusses how IP-PBX phone systems use 911 in the case of emergency.

Unlike phones using traditional telephone service or PSTN, VoIP phones and soft phones can work from anywhere with connectivity to the Internet or the company network. As a result, the traditional association of a phone number to a single physical location in a regional ALI database may be problematic. This is why it is VERY IMPORTANT that V1 VoIP resellers offers customers proper Enhanced 911 (E911) service.

E911 is crucial in circumstances where the caller cannot communicate his or her whereabouts, as it ensures the operator is still able to send emergency response services to the correct location. E911 also involves Selective Routing, whereby the 911 call is routed to the appropriate PSAP (Public Safety Answering Point) based on the caller’s physical location.

Here is an example: a VoIP phone could move from Florida to New York and still keep its Florida telephone number. This poses a problem for call routing as, based on the caller’s telephone number, the 911 call will go to the Florida PSAP rather than to the PSAP closest to the caller’s actual location in New York. It also means that the location associated with the VoIP number in the ALI database may not reflect the phone’s current whereabouts.

Enterprises with centralized IP phone systems may also experience problems with 911. When a branch office connects to an IP-PBX located at the main office, 911 calls will be transmitted to the PSAP serving the main office instead of going to the PSAP serving the branch office.

In addition, because IP phones can move around easily on the company network while keeping the same phone number or extension, keeping track of each phone’s correct, up-to-date location information becomes extremely difficult. Advanced mobility features such as Shared Line Appearance and Extension Mobility only add to the difficulty in pinpointing a caller’s whereabouts.

E911 service automatically displays the telephone number and physical location of the 911 caller on the emergency operator’s screen. This is unlike Basic 911 service, where the distressed caller has to tell the operator where he or she is calling from.

For more information about E911 service, please contact a V1 VoIP team member to answer all your 911 and emergency call related questions.

V1 VoIP Emergency 911 VoIP ERL and ELIN

V1 VoIP has proper emergency phone call information for resellers customers difference between ERL and ELINWhen it comes to VoIP, you need to know about emergency phone call information. V1 VoIP is dedicated to educating our customers about proper emergency VoIP information. For knowing the difference between emergency phone calls like ERL and ELIN is something we educate VoIP and PBX providers on.

ERL stands for Emergency Response Location. It is a specific geographic location to which a 911 emergency response team may be dispatched. For increased accuracy, to reduce response times, or to meet state E911 legislation, the PBX administrator may break down an organization’s campus or buildings into several different ERLs. This allows the organization to provide the PSAP with a 911 caller’s precise location, rather than simply the organization’s main billing address.

For example, each building within a floor or wing of a building may be considered its own ERL; within a given ERL there may be several phones or extensions. In some states, regulations require that organizations maintain ERLs of a specific size or identifiable area (e.g. one ERL per 1000 square feet or per floor).

ELIN stands for Emergency Location Identification Number. ELIN is a ten digit DID number purchased from the local exchange carrier (LEC), and is one way for organizations to provide specific location information to the PSAP for a 911 call. First, enterprise administrators assign an ELIN to each ERL; one ELIN can be used for many phones within an ERL, but each ERL requires at least one unique ELIN. This mapping of ELINs to ERLs must then be loaded into the regional ALI database.

During a 911 call, the ELIN takes the place of the caller’s telephone number as the ANI and is used to route the call to the appropriate PSAP. The PSAP uses the ELIN to query the ALI database and retrieve the caller’s location (i.e. ERL). Should the caller be disconnected, the PSAP can also use the ELIN to call back the extension directly (which requires a temporary mapping of the 911 caller’s number to the ELIN), bypassing the PBX attendant or auto-attendant.

V1 VoIP Provides Lowest e911 Rates for Canada

V1 VoIP offers lowest e911 emergency call rates voip coverage in CanadaThe Canadian Radio and Telecommunications Commission; the Canadian equivalent of the U.S. Federal Communications Commission (CRTC) made a ruling in April 2005, that all VoIP providers must provide 911 emergency service. When it comes to our Canadian resellers and their Canadian customers, V1 VoIP has stood up to meet their needs.

Many VoIP customers have ‘basic 911’ service which puts them in touch with a call center that takes down their address and contacts the closest emergency response center. Rather than have an address come up to a 911 responder or however their geographic location is defined, VoIP phone users are identified with their IP address. If calls are disconnected, the VoIP provider gives the customer’s last known address on file.

However if using the enhanced e911 services provided by V1 VoIP, enhanced 911 service sends location information on customers directly to emergency services.

V1 VoIP’s enhanced e911 solution provides nationwide E911 coverage in both the United States and Canada. Voice service providers simply need to establish a SIP trunk to V1 VoIP’s emergency services network. Customers can update and validate their locations in real-time using V1 VoIP’s provisioning interface, which can be incorporated directly into the VSP’s website.

FCC VoIP E911 Legislation

FCC VoIP e911 legislation for interconnected voip service providers in the United States of AmericaV1 VoIP takes our emergency calling seriously. The Federal Communications Commission (FCC) has established a set of rules and regulations that require interconnected VoIP service providers to deliver E911 services to their subscribers. V1 VoIP’s interconnected VoIP service providers connect the IP realm and the Public Switched Telephone Network (PSTN), allowing subscribers to benefit from increased efficiency by routing calls over the internet.

The regulations established by the FCC are mandatory for all interconnected VoIP service providers, and are designed to protect the safety of VoIP users who expect that when they dial 911, emergency responders know exactly where they are and will quickly arrive on-scene.

Specifically, the FCC requires VoIP service providers to do the following:

1. Deliver all 911 calls to the local Public Safety Answering Point (PSAP), along with the subscriber’s call back number and location information (where the PSAP is capable of receiving it)

2. Offer subscribers a simple and easy way to update their registered physical location, should it change

3.Inform subscribers of the capabilities and limitations of the E911 service they provide
