We started our roots in Information Technology providing consulting services to businesses within Southern California, however, our growth didn't stop there. Our clients required further complexities and a layered security approach to their technology services. Our leading customer service in IT Consulting has branched out to private hosting services like VoIP, Password Managers, SMTP, Virtual Libraries and standard Web Hosting. All of which is decentralized and private. From the encrypted hard drives, to the operating systems, Servers and back out to the edge firewall. We own and control it.

Landline Phone Service questions, answered by experts

VoIP phone services are so common and affordable that it’s unlikely you’ll need a hardwired business phone. Some people may want to avoid VoIP services for reasons of online privacy or to make sure network outages never affect their calls. Otherwise, it’s rare to use an analogy or hardwired system for your first business line.

Costs depend on property size, network complexity, and labor rates.

Types of networks include wired Ethernet for stability, wireless networks for convenience, and powerline networks that use a home's electrical wiring for data transfer. Choose based on your specific internet usage needs.

Yes, most services include signal testing and adjustments for optimal performance.

As long as your landline is corded, meaning your telephone has a handset wired to a base unit on the wall, it will work during a power outage. Cordless phones won’t work without power, and cell phones will run out of battery eventually, so having a corded landline can be vital if your area loses power frequently or for long periods.
