Business Phones That
Work the Way You Do
Your phones are often the first impression customers get. A VoIP phone system from RJ PRO Tech Group gives you clear calls, professional call handling and the flexibility to answer from anywhere.
Because we also manage your network, we make sure your internet, switches and firewall are ready for voice before we go live. That means fewer dropped calls, no finger-pointing between vendors, and one number to call when anything needs to change.

"The Essential IT Buyer's Guide"
Everything you need to know before choosing an IT provider for your small or medium-sized business, so you don't lose time, money, or your sanity.
The challenge
Is Your Phone System Holding You Back?
Businesses across Calaveras, Amador, Sacramento, San Joaquin and El Dorado Counties are still paying for phone systems built for a different era. RJ PRO Tech Group helps you move to modern VoIP without the headaches.
Problem → Solved
Outdated, expensive phone lines
Legacy phone lines and aging on-site PBX hardware cost more every year and are harder to repair. We move you to a cloud phone system with predictable monthly pricing and no hardware closet to maintain.
Problem → Solved
Missed calls & lost customers
Calls that ring out or land in the wrong voicemail cost you business. Auto attendants, ring groups, call queues and smart after-hours routing make sure every caller reaches the right person.
Problem → Solved
Slow or ineffective incident response
Remote, hybrid and field staff shouldn't have to give customers their personal cell number. With VoIP apps, your team makes and takes calls on your business number from anywhere.

FAQ
Frequently Asked Questions
Straightforward answers about how RJ PRO protects your business.
Still have a question?
Talk to a local technician. No pressure, no jargon.
What is a VoIP phone system?
VoIP (Voice over Internet Protocol) sends your phone calls over your internet connection instead of traditional phone lines. Your phone system runs in the cloud, so you get business features like auto attendants, call routing and voicemail to email without expensive on-site hardware.
Can we keep our existing business phone numbers?
Yes. In most cases we can port your existing main line and direct numbers to your new VoIP system. We manage the porting process and schedule the cutover so customers keep reaching you throughout the switch.
What happens to our phones if the internet goes down?
We set up failover rules so calls automatically forward to mobile phones or another location if your office loses internet. Your team can also keep making and taking calls from the mobile app while service is restored.
Will call quality be as good as our current phones?
With a properly prepared network, VoIP call quality is clear and reliable. Because we manage your network too, we check your internet bandwidth and configure your firewall and switches to prioritize voice traffic before you go live.
Can our remote and field employees use the phone system?
Yes. Employees can use desk phones in the office and desktop or smartphone apps anywhere else, all on your business number. Callers see your company number, not a personal cell phone.
Is VoIP secure?
We configure your phone system with strong passwords, encrypted connections where supported, restricted international calling and monitoring for unusual call activity, applying the same security-first approach we use across the rest of your IT environment.
Why get our phones from RJ PRO instead of a phone company?
When your phones, network and IT are managed by one local team, there's no vendor finger-pointing when something goes wrong. You get one number to call, a 24/7 help desk, and technicians who already know your office.
No more chasing your IT company
Why Businesses Choose RJ PRO Over Competitors
you've ever had to follow up five times just to get a simple problem fixed, you're not alone. RJ PRO was built for people who are tired of chasing their tech company. We pick up the phone, speak plainly, and do what we say we're going to do. That's why local businesses across Northern California trust us, backed by a dedicated support team that gets it right the first time.
