SIPPER Office IT is designed for organizations that have moved beyond startup but are not yet enterprise-scale. At this size, you need proper infrastructure but cannot afford a large internal IT team.
Office IT Overview
The single-vendor advantage for growing SMB
Growing businesses often accumulate IT from multiple vendors with no single owner. SIPPER brings everything together — Voice, Network, Security, and Server — into a unified managed service with predictable monthly costs and one phone number to call when something goes wrong.
Predictable Monthly Cost
Hardware and installation priced as a one-time investment. Managed service, Cloud PBX, and calling plans billed monthly at a fixed rate. No surprise repair bills — proactive monitoring catches issues before they become outages.
See Bundle Packages
SIPPER's pre-configured bundles combine Voice, Network, and Security for growing offices. Three tiers — SME Starter (฿105K), Business Growth (฿219K), and Enterprise (฿723K+). All customizable.
Voice & Phones
Cloud PBX and IP phones for the whole office
Yeastar P-Series Cloud PBX handles all internal and external calls — desk phones, mobile app, softphone, and contact center — from a single platform on SIPPER's Pure VoIP Network. Includes SIP Trunk, Thai DID numbers, and calling plan.
Yeastar Cloud PBX + SIP Trunk
Hosted on SIPPER's Pure VoIP Network in Thailand. Extensions, auto-attendant, voicemail, call recording, and call queue included. SIP Trunk with Thai DID numbers and calling plan bundled. No PBX hardware to buy or maintain.
Yealink IP Phones
SIPPER pre-configures all Yealink phones before delivery — plug in and they register automatically. Range from entry-level T31G to executive T54W. Conference phones, DECT handsets, and video phones also available.
Linkus Mobile & Desktop App
Yeastar Linkus UC client lets staff make and receive calls on their laptop or mobile phone using their office extension. Works over WiFi or mobile data. No VPN required. Ideal for hybrid and remote work.
Network & Server
Managed firewall, WiFi, and file server
A properly designed office network has VLANs separating Voice, Data, and Guest traffic, QoS ensuring call quality, and a managed firewall protecting all inbound and outbound connections. SIPPER designs, installs, and manages all of it.
FortiGate Managed Firewall
NGFW protecting your office perimeter with IPS, web filtering, application control, and VPN for remote workers. Managed by SIPPER — policy changes, firmware updates, and monthly security reports included.
WiFi 6 Coverage (UniFi)
Full office WiFi coverage with UniFi U6-Pro or U6-Enterprise access points. Separate SSIDs for staff (WPA2 Enterprise), guest (captive portal), and IoT devices. Centrally managed with roaming optimized for Linkus mobile calls.
File Server & Active Directory
On-premise Dell or HPE file server with Active Directory for user authentication, group policy, and shared drive management. Backup solution included. SIPPER manages server patching, storage, and backup verification.
Managed IT Service
Ongoing IT helpdesk and management
After installation, SIPPER provides ongoing managed IT service — monitoring, helpdesk, PBX changes, firewall management, and scheduled on-site visits. Your staff gets a local IT team without the cost of hiring one.
IT Helpdesk 8×5
Remote helpdesk support for all IT issues — VoIP, network, server, laptop, printer. Ticketing system with SLA response times. Staff call one number for all IT problems regardless of which system is affected.
Proactive Monitoring
24/7 automated monitoring of firewall, switches, access points, server, and PBX. SIPPER is alerted before users notice a problem. Bandwidth usage, security events, and uptime reported monthly.
On-Site Visit (Monthly)
A SIPPER engineer visits your office monthly to verify physical infrastructure, perform preventive maintenance, and address any issues that require on-site attention. No extra charge — included in managed service.
FAQ
Common questions about office IT solutions
What is the typical initial investment for a 100-user office?
A complete 100-user office IT deployment (firewall, switches, WiFi, IP phones, server, installation) typically runs ฿250,000–400,000 as a one-time cost. Monthly managed service, Cloud PBX, and calling plans add ฿20,000–35,000/month. SIPPER provides a detailed quote after a site survey.
Can I start small and expand later?
Yes. SIPPER designs all office IT to scale. You can start with 20 phones and expand to 200 without replacing the core infrastructure. Firewall, switches, and PBX are sized with growth headroom from the start.
Do you handle migration from an old PBX system?
Yes. SIPPER migrates from traditional PABX, IP PBX (Cisco, Avaya, Panasonic), or any SIP-based system. Your existing DID numbers are ported to SIPPER SIP Trunk. Extension numbers can be preserved. SIPPER plans the cutover to minimize downtime.
How is your managed service different from break-fix support?
Break-fix means you call when something breaks and pay per incident. Managed service is proactive — SIPPER monitors your systems 24/7, applies patches, and resolves issues before they affect your business. Fixed monthly cost, no surprise bills.
Do you cover both IT and VoIP under one managed service?
Yes. This is SIPPER's core differentiator. Most IT outsource providers treat VoIP as out of scope. SIPPER manages both — PBX configuration, extension changes, call routing, and voice quality — alongside your network, firewall, and server.
