Phone Systems for Construction Companies

The office, the yard, and every jobsite on one system, with voicemails you can read from a lift.

Construction communication is scattered by nature: estimators in the office, supers across three jobsites, PMs in trucks, and subs on whatever number they answered last. Bids come in on one line, change orders on another, and the lien release the title company needs is sitting on a fax machine back at the yard.

Cannon VoIP pulls that sprawl onto one system: every super and PM carries the company number on the mobile app, voicemails arrive as readable transcripts for people who cannot answer with gloves on, eFax handles permits and lien releases from any laptop, and the bid line never rings out. Flat $34 per extension, no contracts.

Jobsites eat phone calls

A super on a slab pour is not answering the phone, and should not be. But the call they missed might be the inspector moving up a visit, a sub confirming tomorrow's crew, or the GC with a question that stops work if it waits a day. On most systems that call becomes a voicemail nobody checks until the truck ride home, and the day is already lost.

The office side leaks differently: bid invitations have deadlines, and an estimator who misses the call sometimes misses the list. Meanwhile calls from field cells get screened by GCs and homeowners alike, because an unknown number at 7 AM looks like spam even when it is your PM confirming access.

What we set up for construction companies

The company number, jobsite to office
Supers and PMs carry their extension on the mobile app: calls out show the company name, calls in follow rules they set, and the office transfers a call to a jobsite like it is down the hall.
Voicemail you can read from a lift
Every voicemail is transcribed and delivered to email and the app, so a super on a pour reads the inspector's message between tasks instead of dialing into a mailbox at 6 PM. Nothing waits for the truck ride home.
Calls GCs actually answer
Branded Caller ID puts the company name and logo on the screen when your team calls GCs, subs, inspectors, and homeowners. Fewer screened calls, fewer stalled questions.
A bid line that never rings out
Route bid invitations to an estimator ring group with fallbacks, then to transcribed voicemail that emails the whole estimating team. Deadlines stop dying in one person's mailbox.
Permits and lien releases by eFax
Title companies, municipalities, and lenders still fax. Cloud eFax sends and receives from email or the browser at $10 per month, with an archive you can search when the closing package needs the release from March.
Crew and client texting
"Crew on site at 7," gate codes, and schedule changes go out as texts from the company number, including broadcasts to a sub list with automatic opt-out handling.

Why contractors switch to Cannon VoIP

Construction headcount moves with the backlog. Flat $34 per extension, month to month, means the phone system scales with the org chart in both directions, and nobody pays January prices for a July roster. Texting and transcription are included rather than metered.

The company number is often decades old and painted on every truck: it ports for $15 per line, usually next business day, with about two minutes of downtime. Trailers and yard signage never notice the switch.

Offices and trailers change constantly, and hardware keeps up: preconfigured phones ship overnight AM and register themselves wherever they land, and a $99 ATA keeps an old analog line or fax machine working in a trailer that has seen three projects.

What a typical setup looks like

A typical GC runs office, estimating, and accounting extensions on desk phones, with every super and PM on the mobile app, at $34 per extension. The main menu routes "current projects" to the PM group, "new work and bids" to estimating, and "accounts payable" to a voicemail box that emails transcripts to accounting.

After hours, an emergency option rings the on-call super's cell through the app while everything else takes messages. Companies that field a lot of homeowner calls put the AI receptionist at its flat $65 on the front of the line, in English and Spanish.

Common questions from construction companies

Our supers won't learn a new phone system. What's the real lift?
The app is a dialer with the company number on it, and voicemail arrives as text they read like a message. That is the whole learning curve for the field. The routing complexity lives in the office portal where it belongs.
Can the office transfer a homeowner straight to the super on that job?
Yes. Extensions transfer to app users the same as desk phones, so "let me get you the super on your project" is one button, not a written-down cell number the homeowner will use forever after.
Do we still need the fax machine in the trailer?
Probably not: eFax handles permits, releases, and pay apps from any laptop. If a trailer machine must live on for sentimental reasons, a $99 ATA keeps it running on the same system.

Bilingual crews are the norm in this business: the AI receptionist and your texting both work in Spanish, and the office menu can offer both languages up front.
