In today's rapidly evolving telecommunications landscape, understanding the intricacies of emergency call handling via Voice over Internet Protocol (VoIP) is crucial. Skyetel is committed to ensuring that our customers are well-informed about emergency VoIP protocols, particularly when it comes to differentiating between critical components such as Emergency Response Location (ERL) and Emergency Location Identification Number (ELIN). This knowledge is vital for both VoIP users and Private Branch Exchange (PBX) providers.
What is Emergency Response Location (ERL)?
Definition of ERL
The term Emergency Response Location, abbreviated as ERL, refers to a specific geographic location where a 911 emergency response team can be dispatched in the event of an emergency. The importance of ERL lies in its ability to provide a precise location, thereby enhancing the accuracy of emergency responses and reducing response times. This is not only beneficial for safety but is often required to comply with state E911 legislation.
Importance of ERL in Emergency Situations
To improve the precision of emergency response, PBX administrators may opt to divide an organization's premises into multiple ERLs. This is particularly useful in large campuses or multi-building organizations. By segmenting locations into distinct ERLs, organizations can provide Public Safety Answering Points (PSAPs) with detailed location information rather than just the main billing address. For example, each building, floor, or wing might be assigned its own ERL. Depending on state regulations, organizations might be required to maintain ERLs that cover a specific area, such as one ERL per 1,000 square feet or per floor.
Exploring Emergency Location Identification Number (ELIN)
Definition of ELIN
Emergency Location Identification Number, known as ELIN, is a ten-digit Direct Inward Dialing (DID) number acquired from the local exchange carrier (LEC). ELIN is essential for providing PSAPs with specific location information during a 911 call.
How ELIN Works in Conjunction with ERL
Enterprise administrators are tasked with assigning an ELIN to each ERL within their organization. Typically, one ELIN can be associated with multiple phones within an ERL, but each ERL must have at least one unique ELIN assigned. This mapping of ELINs to ERLs is crucial and must be uploaded to the regional Automatic Location Identification (ALI) database.
During an emergency call, the ELIN replaces the caller's telephone number as the Automatic Number Identification (ANI). This process ensures that the call is routed to the correct PSAP. The PSAP uses the ELIN to access the ALI database, retrieving the caller's precise location, which is the ERL. In cases where the caller is disconnected, the PSAP can utilize the ELIN to call back the extension directly. This direct callback is possible due to a temporary mapping of the 911 caller's number to the ELIN, bypassing the PBX attendant or auto-attendant systems.
Ensuring Comprehensive e911 Coverage
For those interested in learning more about emergency VoIP information and ensuring comprehensive E911 coverage, it is advisable to consult with experienced professionals in the field. Proper understanding and implementation of ERL and ELIN are essential for meeting regulatory requirements and ensuring swift emergency responses.
