Kari's Law Compliance is Now a Federal Law, Ray Baum's Act to take effect soon. Act Now!

Is your phone system in compliance with Kari's Law? It is now a federal law for new multi-line telephone systems to support this dialing feature. Kari's Law requires direct access to 9-1-1 service without the user having to first dial an initial number, digit, prefix or other access number or code before dialing 9-1-1.
Learn more about 
Kari's Law here. Signed into law in 2018, the law went into effect on February 16, 2020.

Ray Baum's Act requires outbound caller ID on new phone systems to provide address, floor, room or suite number for 911 calls. Affected by Ray Baum's Act include enterprise companies, multi office companies, campus for schools and universities, hospitals, hotels, retail, financial and large warehouses. 

We can help. Contact our office today and get compliant if you are not!  Act now!  All new phone system installations by Office Telesystems include Kari's Law compliance and Ray Baum's act compliance.
