Houston, TX
Hosted VoIP for Small Business
Keller PBX is a locally owned business phone provider in Houston. We set up hosted systems for small businesses — clinics, CPAs, law offices, trades, and restaurants — so callers reach the right person, and your number stays yours.
Why Keller PBX
A Houston phone system that still feels like a neighbor.
Built for small business
Built for small businesses that need a main number, menus, and voicemail — so callers reach the right person.
Keep the number you already have
Porting is handled for you. We test on a temporary number first, then move on a weekday you pick.
Who we serve
Offices that answer the phone for a living.
If a missed call is a missed job, a missed patient, or a missed client, this is the size of business we set up for.
Clinics
A main line that routes to the front desk, billing, or an after-hours cell.
CPAs
Seasonal hours, a clean greeting, and voicemail that lands in email.
Law offices
Press-1 menus so intake, billing, and attorneys are not the same ring.
Trades
A shop line that rings the crew, then forwards when everyone is on a job.
Restaurants
Reservations, catering, and after-hours — each with its own path.
What you get
Everything your business phone needs.
Everything a small business needs from a phone system, set up for you.
Call recording with transcription
Record calls and get a searchable text transcript. A recording announcement plays by default.
Voicemail to email with transcription
Included with every user. Voicemail arrives as an audio file plus a written transcript.
Fax to email
Incoming faxes arrive as PDFs in your email. Keep your fax number.
Extensions and voicemail
Each person gets an extension and a mailbox.
Auto attendant
A “press 1 for…” menu so callers route themselves before anyone picks up.
Hours and holidays
Business hours, after-hours treatment, and observed holidays on the calendar.
Ring groups
A shared line can ring a team together — front desk, shop, or on-call group.
Softphones and desk phones
Linphone on mobile and desktop, Yealink desk phones, and analog adapters for fax or analog lines — set up for you. Compare phones.
Custom professional greeting
A professional greeting for your auto attendant, written and recorded for you.
Local support
When you call, you reach our team in Houston.
Talk to someone who knows your office by name. No phone trees between you and your support team.
People who know the office
You talk with the same Houston team that set the system up — not a script and a ticket number.
Close enough to drive over
Local people who can drive over when it matters: a new phone, a move, or a cutover day.
Business hours, on purpose
Live phone support is Monday through Friday, 8:00 a.m. to 6:00 p.m. Central Time. Open a ticket or send us a message any time.
Switching
How switching works
Three plain steps. No overnight cutover unless you ask for a scheduled weekday move.
1
Tell us about the office
Who answers, how many seats, and whether you are keeping your number.
2
We build and test
Your system goes live on a temporary number so you can try menus, voicemail, and phones first.
3
Your number moves
Porting is scheduled on a weekday. Typical U.S. ports take several business days and depend on the losing carrier.
