Overview
AG Network Cabling designs, installs, and supports business VoIP phone systems for companies across Southern California. Whether you're replacing an aging phone system or setting one up in a new space, we build VoIP that lowers your call costs, adds features you didn't have before, and scales as you grow.
VoIP runs your phone calls over your internet connection instead of traditional phone lines, which is what makes it cheaper and far more flexible. But a business phone system is only as reliable as the network underneath it. That's our advantage: we handle the cabling and the phones together, so the system is built on a foundation that can actually carry it.

What's included
Our VoIP services cover the full setup, from the network to the handsets:
VoIP phone setup — installation and configuration of desk phones and conference units.
SIP trunking — connecting your phone system to the network for lower per-call costs.
PSTN integration — bridging traditional phone lines with your VoIP system where needed.
IP phone configuration — programming extensions, call routing, voicemail, and features by user or team.
Softphones — phone service on laptops and mobile devices for remote and traveling staff.
Our process
Every project starts with a free consultation. We look at how your team actually uses the phone, how many users you have, and what your current setup costs, then recommend a system with a written quote covering equipment, configuration, and timeline before any work begins.
From there we handle installation, configuration, and testing, including the cabling and network side. We make sure calls are clear and features work before we hand it off, and we're there for support afterward.
Who it's for
VoIP makes the most sense for businesses that live on the phone or are outgrowing what they have. A growing company adding staff needs extensions it can spin up without a technician visit. A business with remote or multi-site teams needs everyone on one system regardless of location. A company watching its overhead wants the lower per-call costs and the reporting to back it up. We set up VoIP for offices, hospitality, and multi-location businesses where the phone is still how work gets done.
Frequently asked questions
How much can VoIP save us over a traditional phone system?
Savings come mostly from lower per-call and line costs through SIP trunking, and from dropping separate phone-line bills. The exact amount depends on your call volume and current setup, which we'll review in a free consultation.
Can we keep our existing phone numbers?
Yes. Existing business numbers can be ported over to the new VoIP system, so you keep the numbers your customers already know.
Will VoIP work with our current internet connection?
In most cases, yes, though call quality depends on having enough bandwidth and a properly configured network. We assess this during the consultation, and since we handle cabling too, we can fix the network side if it needs it.
Can staff use the system from home or on the road?
Yes. Softphones put your business phone system on laptops and mobile devices, so remote and traveling staff use the same extensions and features as everyone in the office.
