MultiTEL's Enhanced 911 (E911) solutions give you the tools you need to protect your most valuable asset: your people. Our solution associates a 9-1-1 caller's location with their phone number, passing it along to the PSAP. This kind of automatic transfer of information will help you provide vital, lifesaving information to the 9-1-1 PSAP operators. The capability to offer access to emergency services is not only a regulatory obligation to many carriers but also a must have from a commercial standpoint. All enterprises considering migrating their telephone services to VoIP require the possibility of access to the local emergency services. MultiTEL offers this access to companies located in US and Canada, delivered via IP/VoIP. This service complies with local regulations within US/CA.


Our E911 services rely on a geographically diverse network, with points of access in Southfield, MI, Houston, TX and New York, NY and San Francisco, CA. We offer truly resilient networking access along with multi-carrier connectivity. This way, even in the event of a natural catastrophe, our E911 services are still accessible.

How it works

We provide API access so you can integrate our services into your application. Our API provides address validation along with free location updates so you will be able to maintain correct address/subscriber phone number association at no cost, regardless of how many hundreds of daily updates you need to make.
At the core of our service, we run a mix of multiple Cisco routers and softswitches which will route your calls based on their origination (called number) to the corresponding PSAP. The location of the phone number is forwarded to the PSAP in real time so any updates on the address that you might have made will be immediately available when you call E911. All links with local emergency centers are regularly tested.
