FreePBX, Sangoma, Grandstream, and Cisco systems — all managed through your IT Center VoIP portal. Replace copper POTS lines, cut phone bills, and gain enterprise calling features your business has never had before.
3CX Authorized Partner · FreePBX SpecialistsFrom cloud-hosted PBX to physical desk phones — IT Center handles procurement, provisioning, configuration, and ongoing management under one agreement.
IT Center deploys and manages FreePBX and Sangoma PBX systems either cloud-hosted on our infrastructure or on-premise at your office. Full administrative control, redundant SIP registration, and automatic failover keep your phones online even during maintenance events.
The Grandstream GXP2170 is our recommended enterprise desktop phone — 12 SIP lines, HD audio, color display, Bluetooth headset support, and a built-in PoE gigabit switch. Every handset is provisioned automatically from our template server and ships pre-configured to your extension.
Elastic SIP trunks through Twilio and Vonage give you unlimited concurrent call paths that scale with your business — pay only for what you use. Number porting, toll-free numbers, and local DIDs across all US area codes are supported. Redundant carriers eliminate single-point-of-failure.
Configure a professional multi-level IVR auto-attendant with custom greetings for business hours and after-hours. Hunt groups ring multiple extensions simultaneously or in sequence. Call queues with hold music and position announcements handle inbound volume professionally, even without a receptionist.
Every voicemail is transcribed and delivered to your inbox as both text and an audio attachment — no missed messages. On-demand and automatic call recording (with legal compliance prompts) is stored securely in the cloud. Search and replay any recorded call through the VoIP portal.
IT Center configures dispatchable location records for every extension as required by KARI's Law and RAY BAUM's Act. Remote and mobile workers have their locations updated dynamically. Annual E911 validation reports are generated for compliance documentation and audit readiness.
Every IT Center VoIP client gets web-based admin access to their PBX — whether that’s a 3CX management console, the FreePBX administration interface, or your hosted Sangoma deployment. Full self-service for the everyday changes; full IT Center support for everything else.
Provision a new employee's extension, set their voicemail PIN, assign ring groups, and push the configuration to their desk phone — all in under two minutes, without calling support.
View inbound and outbound call detail records in real time. Filter by extension, date range, or caller ID. Export to CSV for billing review or compliance audits.
Upload custom holiday greetings, update your after-hours message, or change your auto-attendant menu options directly from the portal — no ticket, no wait, no vendor dependency.
Play, download, or delete voicemails and read AI-generated transcripts. Shared mailboxes let reception teams access group voicemail queues collaboratively.
The FCC has ended the requirement for carriers to maintain traditional copper POTS lines. AT&T, Verizon, and others are actively retiring analog infrastructure — sometimes with as little as 90 days' notice.
Fax machines, alarm panels, elevator phones, credit card terminals, and HVAC systems often rely on copper lines. IT Center audits every analog dependency and migrates each one to a modern, compliant alternative before your carrier pulls the plug.
We document every device on copper: analog phones, fax lines, alarm dialers, elevator emergency phones, and door intercoms. Nothing gets missed.
We initiate number ports with your carrier, procure ATAs (Analog Telephone Adapters) for legacy devices, and configure VoIP replacements in parallel so there is zero interruption to service.
Each device is migrated individually and tested end-to-end — including test calls to 911 — before the analog line is cancelled. Your alarm company and elevator contractor are coordinated directly by IT Center.
All migrated lines are registered in our monitoring platform. SIP registration failures, jitter events, and quality alerts are handled by our NOC before users notice any degradation.
All packages include web-based PBX administration, HD voice, Kari’s Law E911 compliance, voicemail-to-email, and IT Center managed support. Hardware is quoted separately.
All pricing is quoted based on your specific configuration. Hardware, number porting fees, and SIP trunk usage are itemized separately. Contact IT Center for a detailed quote.
We'll walk you through a live FreePBX or Sangoma demo using your actual business scenarios — call queues, auto-attendants, call recording — so you can see exactly what you're getting before signing anything.
