QUICK REFERENCE GUIDE | VESTA® 9-1-1 & VESTA® SMS
A CLEAR STRATEGY TO INTEGRATED TEXT-TO-9-1-1
The VESTA® SMS solution is an easy way for PSAPs to adopt Text-to-9-1-1 because it is integrated into the VESTA® 9-1-1 system. Integrated Text- to-9-1-1 is the most effective way to implement SMS because with the integration, Telecommunicators handle SMS calls just like they do voice calls. As a result, Telecommunicators experience less change in their day-to-day operations, and they get up to speed on using SMS more quickly. Both of these critical points minimize disruption in the PSAP as the new application is implemented.
The purpose of this document is to answer frequently asked questions about implementing integrated Text-to-9-1-1 and provide a clear picture of the steps and the roles of the different parties involved.
FREQUENTLY ASKED QUESTIONS
What are the delivery methods for Text-to-9-1-1?
•Legacy – TTY/TDD interface - within the call handling equipment to receive and service Text-to-9-1-1 services.
•Transitional – Web browser based - using connectivity to TCCs (Text Control Centers), typically over an Internet connection.
•NG9-1-1 – VESTA SMS - Fully integrated Text-to-9-1-1 as part of the NG9-1-1 call handling solution that is SIP/MSRP (Session Initiation Protocol/Message Session Relay Protocol) based, i.e., VESTA 9-1-1.
What are the benefits to the VESTA SMS integrated solution?
•You have a Next Generation solution - NENA i3 compliant.
•Your training is simplified. Telecommunicators don’t have to learn a new process to handle Text-to-9-1-1 calls from how they handle voice calls because the work flow is consistent.
•You reduce the chance of error because Telecommunicators are not required to toggle between applications when handling voice and text calls.
•There is no impact to voice trunk capacity.
•You save time in processing a text call and therefore increase your operational efficiency.
What is the TCC (Text Control Center)?
When sending a text call to 9-1-1, the caller requesting emergency assistance sends a Text-to-9-1-1 as they would to any short message code, SMS. The text is routed by the wireless carrier to the TCC. The responsibility of the TCC is to transfer the SMS call to the correct PSAP for handling.
Do I have to be on an ESInet for VESTA SMS?
No, you do not. An existing ESInet connectivity can typically be leveraged, but it is not necessary for you to have an ESInet in place for the IP connectivity. If there is no ESInet, then dedicated circuit(s) may be required depending on your needs. The connectivity to the TCC is a cost the PSAP incurs.
Do I need to connect to multiple TCC providers to get full coverage across all major wireless carriers?
No, you do not. The national TCC providers will provide Text-to-9-1-1 aggregation, providing coverage across all carriers.
