Serving Central Coast Since 1982
Serving Central Coast Since 1982
Cut your phone bill, unify your team on one platform, and get local support from a team that has served San Luis Obispo businesses since 1982. No national call centers, no overseas support queues.
Most SLO businesses overpay for phone systems that haven't changed since the 1990s. VoIP (Voice over Internet Protocol) replaces your traditional phone lines with an internet-based system — cutting costs by 40–60% while adding features your old system could never support: video calls, mobile apps, auto-attendant, voicemail-to-email, and more.
CENCOM has been the Central Coast's go-to telecommunications partner since 1982. We've helped businesses from downtown San Luis Obispo to the airport corridor and Cal Poly area make the switch to VoIP without a single day of downtime. Our technicians are local — not a call center in another state — so when you need support, a real person picks up.
We're a certified Wildix Gold Partner and can deploy cloud-based or on-premises VoIP systems depending on what makes sense for your business size and setup.
CENCOM VoIP systems come with every feature your team needs — installed and configured by local technicians who know your building.
Professional call routing, custom greetings, hunt groups, and auto-attendant — all managed from a browser. No on-site server required.
Voice, video, team chat, file sharing, and screen sharing in one browser-based platform. Works on desk phones, desktop, and mobile — anywhere your team works.
Your business number rings on your mobile phone. Transfer calls, check voicemail, and join conference calls from anywhere — your clients always reach a real person.
Voicemails delivered as audio files to your inbox. Read transcriptions, respond faster, and never miss a message — even when you're out of the office.
Add or remove users in minutes. Whether you're a 3-person office or a 200-seat operation, VoIP scales instantly — no new hardware, no technician visit required.
Cloud redundancy means your phones keep working even if your internet goes down temporarily. And when you need help, CENCOM's local SLO team responds same day.
Most San Luis Obispo businesses save 40–60% on their phone costs within the first year of switching to VoIP.
Answers to the questions SLO businesses ask us most before switching to VoIP.
VoIP (Voice over Internet Protocol) routes phone calls over your internet connection instead of traditional copper phone lines. For San Luis Obispo businesses, this means lower monthly costs, better call quality, and features like mobile apps, video calling, and voicemail-to-email that traditional systems can't match. CENCOM configures everything locally — your team keeps their existing numbers and gets trained before we leave.
VoIP systems for SLO businesses typically run $30–$60 per user per month for cloud-hosted systems, with minimal upfront hardware costs. Most businesses save 40–60% compared to their traditional phone bills. CENCOM provides free consultations with exact pricing for your specific setup — office size, number of users, and features needed all factor in.
CENCOM is a Wildix Gold Partner — our primary VoIP recommendation for most SLO businesses. Wildix is a browser-based unified communications platform that includes voice, video, messaging, and file sharing in one system. We also install and support Cisco, Mitel, and other VoIP platforms depending on your existing infrastructure and requirements.
Yes. CENCOM handles the full number porting process — your existing San Luis Obispo business numbers transfer to the new VoIP system with zero interruption. Your clients dial the same number, and you don't need to update any of your marketing materials or business listings.
Yes — cloud VoIP systems like Wildix run on 99.9% uptime SLAs with built-in redundancy. If your internet goes down, calls automatically roll over to mobile phones so you never miss a customer. CENCOM also assesses your existing internet connection before installation to make sure it can handle VoIP traffic — we won't install a system that won't perform.
Most cloud VoIP systems are up and running within 1–5 business days after your consultation. We schedule installations around your business hours to minimize disruption. Our local SLO team handles everything — cabling, hardware setup, software configuration, number porting, and staff training — before we hand over the keys.
Not necessarily. Many existing desk phones are VoIP-compatible and can be reprogrammed to work with the new system. CENCOM audits your current hardware during the consultation and tells you exactly what can stay and what needs replacing — we won't recommend new hardware unless it's genuinely needed.
Our local technicians cover every neighborhood in SLO — no travel fees, no waiting days for someone to drive from out of town.
We also install and support VoIP systems throughout San Luis Obispo County and the Central Coast, including the Five Cities area, Paso Robles, and Atascadero.
