A San Marcos number that isn't tied to a building

Customers trust a local number. With a 512 or 737 line you look like the San Marcos business you are — but the phone system lives in the cloud, so it works the same whether your team is at the office, on a job site across Hays County, or working from home.

And you're not buying a phone system anymore. Seats are month-to-month and scale as you hire, so a growing San Marcos business can start with a handful of lines and add more in minutes — no forklift upgrade, no closet full of PBX hardware to maintain.

  • Local 512, 737 numbers, or port the number you already have
  • Calls, business texting, video meetings, and voicemail in one app
  • AI transcription, call summaries, and an auto-attendant / IVR
  • Works from any device, anywhere — office, field, or remote

Can I get a local San Marcos phone number?

Yes — 512, 737 area codes are all available, and we handle the setup. You can point several local numbers wherever you like.

Can I keep my existing number?

Yes. We port your current numbers over — including your main line — with no downtime, so customers never notice the switch.

That's the whole point of cloud phone. The same number rings on a desk phone, a laptop, or the mobile app — so it doesn't matter where your people are across Hays County.

No. Many San Marcos teams run entirely on the app on laptops and phones. Keep or add desk phones if you prefer — it's your call.
