Business Phone Systems in San Francisco
Enter your San Francisco zip code and describe your office: how many users and how many locations. Local providers reply with quotes.
A small law firm on Montgomery Street and a ten-person design studio in the Mission have the same problem from opposite directions. One has a phone system older than its newest associate. The other has none, just everyone's cell, and clients are starting to wonder who to call.
Two kinds of San Francisco office
The Financial District and the older towers carry a lot of law, finance and consulting. Those firms often run a PBX installed years ago, with direct-dial numbers that clients have in their contacts. The number matters more than the box, and porting is the part of the project to plan carefully. Direct lines for partners should land on the new system the same morning as the main line.
South of Market, Mission Bay and the Dogpatch side are different. Startups and creative shops there often start with mobile phones and graduate to a hosted system when a customer asks for a main number and a proper greeting. Mission Bay also has the UCSF campus and a cluster of clinics and biotech tenants, who want call recording and voicemail to email, and phones that talk to their scheduling software.
Hosted fits the city
San Francisco real estate rewards flexibility. Leases are short, and half the staff is home two days a week. Hosted VoIP lets the phone follow the person, which beats rewiring a floor you will leave in three years.
Wiring in older buildings is a real constraint. Some Victorians and brick-and-timber lofts have no clean path for cabling, and the building may limit what you can run through the walls. A hosted system with wireless-friendly phones or softphones avoids most of that. Ask the provider whether they have worked in your building before.
One more local wrinkle: many San Francisco offices are subtenants, sharing a floor with another company. If your suite shares an internet line with your neighbor, the phone system will compete with their video calls for bandwidth. Ask for your own circuit, or at minimum a quality setting on the router that puts voice first.
Hotels and shops around Union Square and Fisherman's Wharf peak on weekends and in summer. Ask how queue and greeting settings change by day, and whether the front desk can switch them without calling the provider.
If your office is a Victorian conversion in the Mission or Hayes Valley, have the installer walk the floor first. A phone that needs a jack in a room with no jack is the usual surprise.
Internet carriers and the second line
Comcast and AT&T are the usual carriers, with Lumen circuits downtown. Pick based on what your building already has. A good provider will check which carrier is actually in the basement before quoting a circuit, instead of assuming.
Because earthquakes and power events are part of life here, build in a way to keep working. That means a second connection or cellular backup, and a call-forwarding plan that sends the main number to cell phones when the office is unreachable. Ask to see how it works before you sign.
In a high rise the riser is the bottleneck. Many towers control who may pull cable through it and keep an approved list of vendors. A provider who has worked in your tower knows the engineering office; one who has not may quote a circuit the building will not let anyone install. Get the answer in writing so the install date is not a guess.
Across the water and down the Peninsula
San Francisco providers reach Daly City and South San Francisco without much trouble. South San Francisco is biotech country, with lab and office tenants who need many extensions on one account and sometimes a separate conference system. San Mateo and the Peninsula corridor sit a little farther down.
Oakland, Berkeley, Alameda and San Leandro are on the east side of the bay. A provider that serves both sides can bring an office in Oakland's Jack London Square and one in the Financial District onto a single system, so a call from one to the other is just an extension. Berkeley has university-adjacent medical and research offices. San Rafael, in Marin, is a short drive over the bridge but has its own local providers, and it is worth asking whether a city-based vendor charges extra to go there.
The quote that looks thin often leaves out the desk phones. Count the handsets, then count the conference rooms. A modern conference phone is not a small line item, and a firm with six conference rooms notices.
Questions worth asking
- Can the provider keep every existing direct number, including the fax line?
- Does emergency calling register a specific floor and suite in a large building?
- Can staff text customers from the office number, and is that extra?
- If we shrink or move, what does it cost in contract terms to downsize?
Law, healthcare and finance still depend on fax, and some providers dodge it. Cloud fax that delivers to email is routine, so put it in the quote. Call recording is common in finance and in medical scheduling, and it raises consent questions that differ by state. Ask how the provider handles announcements to callers, and take the question to your own attorney too.
