Every system we install dials 911 directly with no prefix, notifies a person on site the moment 911 is dialled, and sends the caller's dispatchable location, street address plus suite, to the 911 center. We configure both on install day. Netexem is NENA company identifier NETEX.
Netexem signs each outbound call with its own certificate under the FCC's caller-ID authentication framework, so the carrier on the other end can confirm the call really comes from your number. Our Robocall Mitigation Database certification is what lets other US carriers accept our traffic.
Call detail, voicemail and account data are Customer Proprietary Network Information under FCC rules. Netexem certifies its CPNI safeguards to the FCC every year and never sells or shares call records.
The FCC's registration for every company that provides interstate telecommunications or interconnected VoIP in the United States. The public record shows the legal name Netexem Inc, the Tustin office address, the officer of record and the agent for service of process. FCC Registration Number (FRN) 0036809291.
The FCC's public register of voice providers that have certified how they stop illegal robocalls on their network. A provider that is not listed may not have its calls carried by other US carriers.
STIR/SHAKEN is the caller-ID authentication framework the FCC requires of US voice providers. Netexem holds its own account with the policy administrator and signs every outbound call with its own certificate at the highest level, attestation A, which is what lets a receiving carrier mark a customer's call as verified instead of "Spam Likely".
The industry code that identifies Netexem as a carrier in number-porting, routing and billing systems. It is the same code used as the STIR/SHAKEN Service Provider Code above.
State authority to provide interconnected VoIP service to California businesses under the CPUC's 2024 VoIP decision (D.24-11-003). Netexem files the annual report and keeps the performance bond the Commission requires.
The identifier a 911 center uses to see which carrier is responsible for a phone number, kept in NENA's national Company Identifier database. Netexem's identifier is NETEX; it is how a dispatcher reaches us about one of our numbers.
The city license for our one office at 17662 Irvine Blvd #20, Tustin, CA 92780. The City of Tustin has no public lookup; the license certificate is available on request.
The yearly certification that Netexem protects Customer Proprietary Network Information: who you call, when, and your account details. Interconnected VoIP providers file it like any telephone company.
Netexem is listed in the Chamber's public member directory with the same address and 714 number as this site.

Yes. The FCC's Form 499 database lists Netexem Inc, Filer ID 837524, at 17662 Irvine Blvd #20, Tustin, CA, current as of April 1, 2026, and the Robocall Mitigation Database lists Netexem as RMD0027533.
Yes. Netexem has its own account with the STIR/SHAKEN policy administrator (STI-PA account 102325) and signs every outbound call with its own certificate at attestation A, the highest level, so a receiving carrier can verify that the caller ID is real.
Signed calls from a number used normally are far less likely to be labelled. Labels are set by the receiving carrier's analytics, not by Netexem, so no provider can promise they never appear. If one of your numbers is flagged, call 714.444.0550 and we file the correction with the carrier.
Every system we install dials 911 directly with no prefix, sends an on-site notification when 911 is dialled, and delivers a dispatchable address with the suite number, as Kari's Law and RAY BAUM's Act require. Netexem is registered with NENA as company identifier NETEX, the responsible carrier for its numbers.
