What to know about business phone systems in Avondale
Your phones depend on your internet and power
Modern business phones run over the internet, so the connection into your building matters. Cox Business and Quantum Fiber list business internet for Avondale, and Wyyerd Fiber announced fiber availability on June 30, 2026. Availability is by address, so check each provider before you plan around one.
Monsoon season brings outages
The City says power outages are common during monsoon season, mid-June through the end of September. Avondale has both SRP and APS electric customers. SRP's outage line is (602) 236-8888, staffed around the clock. A battery backup on the switch and router keeps phones up through a short outage.
Street work can cut your line
ADOT is rebuilding the Loop 101 and I-10 system interchange, with construction that began in mid-May 2026 and takes about three years. Street and freeway work is one way buried lines get damaged. A second connection, or a mobile backup, keeps your phones working when one line is cut.
Phone wiring follows the 2024 codes
Avondale's building codes are the 2024 International Codes and the 2023 NEC, effective January 1, 2026. Low-voltage wiring is not on the city's permit exemption list, and we confirm with Building Services at (623) 333-4000 whether your job needs a permit.
Cloud phones, on-site systems and PBX
A PBX is the box that routes calls inside a business. Older PBX systems sit in a closet and use phone lines. Most small businesses now use hosted VoIP, where the routing runs in the provider's cloud and your phones connect over the internet.
Some businesses keep an on-site PBX because the existing system works, they need special hardware like paging, or they want calls to stay on their own equipment. We install either and tell you which fits.
What the system should do
Start from how calls actually arrive. A restaurant needs a host stand that picks up fast and a manager line. A clinic may need several lines, hold music and an after-hours message.
- Ring groups, so a call rings the right people.
- An automated greeting that gives hours and options.
- Voicemail that arrives by email.
- Call forwarding to a cell phone when the office is closed.
- Overhead paging in a warehouse or large dining room.
Wiring and power for the phones
Desk phones usually run on PoE, so one network cable carries power and calls. Each phone needs a cable back to a switch, which is why phone jobs often include structured cabling. Wireless handsets and softphone apps suit staff who move around.
Put the PoE switch on a battery backup and the phones keep working through a short outage, as long as the internet connection does too.
Emergency calls and addresses
A 911 call from an internet phone needs the correct address registered, and every phone's location must be updated when a phone moves to a new suite or floor. We register the address for each location at setup and show you how to change it.
Setting up the phones
- Count phones, lines and call flows on site.
- Choose the system, handsets and cabling.
- Run cable and set up phones and network around your hours.
- Program greetings, ring groups and voicemail.
- Test inbound and outbound calls. Service runs Monday to Friday, 8 AM to 5 PM.
