VoIP & Telecom.

Sangoma hosted PBX, SIP trunking, contact-center features, mobile softphones, paging, and number porting.

VoIP and telecom services from Maverick are built on Sangoma, the company behind FreePBX — the largest open-source VoIP platform in the world. We deploy hosted PBX, SIP trunking, contact-center features, mobile softphones, paging, and number porting. The underlying technology is mature, well-supported, and substantially cheaper than legacy vendors like RingCentral or Vonage.

Why Sangoma

VoIP vendor selection comes down to three things: call quality, total cost, and how badly they will squeeze you on features as you grow.

Sangoma wins all three for the SMB and mid-market. They are the maintainers of FreePBX (the largest open-source VoIP platform globally) and their commercial Business Cloud product is built on the same proven engine. Call quality is excellent — they run their own carrier-grade infrastructure. Cost per seat runs 30 to 50% lower than RingCentral or 8x8 for equivalent features. And critically, they don't lock advanced features behind ridiculous tier escalations.

For clients with specialized needs (legacy gear, on-prem requirements, complex call flows) Sangoma's on-premises Switchvox platform is also available.

What we deliver

Hosted PBX (Sangoma Business Cloud)

Cloud-hosted phone system with everything included: extensions, voicemail, IVR (auto attendant), call queues, hunt groups, ring groups, conferencing, paging, mobile softphone, desktop softphone, fax, SMS. Per-user pricing — no nickel-and-diming for features.

SIP trunking

For clients with existing PBXs (Cisco, Avaya, 3CX, FreePBX) we deliver SIP trunks with carrier-grade reliability. Pay-as-you-go or unlimited bundles. Geographic redundancy. E911 compliant.

Contact center

Skills-based routing, call recording, real-time queue dashboards, supervisor monitoring/whisper/barge, reporting and analytics. Suitable for inbound support, outbound sales, or blended operations up to a few hundred seats.

Mobile + desktop softphones

Take your extension anywhere. Mobile app on iOS/Android with your business number for outbound calls. Desktop app on Mac/Windows with full feature parity.

Number porting

We handle the entire porting process — collecting CSRs, filing port requests, coordinating timing, testing. Numbers usually port in 5 to 10 business days with zero downtime to your inbound calls.

Microsoft Teams integration

Direct Routing via Sangoma's certified SBC service. Users keep Teams as their main interface for calls, but they're placing real PSTN calls through your Sangoma infrastructure with full PBX features in the background.

Common Questions About VoIP & Telecom

How much does VoIP cost per seat?

Sangoma Business Cloud typically runs $20 to $35 per user per month for the full feature set. Contact-center seats add $15 to $25 depending on features needed. Compare that to RingCentral or 8x8 at $40 to $55+ per seat for equivalent capability. SIP trunks for existing PBXs run $20 to $30 per channel per month.

Will my phone numbers transfer to the new system?

Yes. Number porting is part of every VoIP deployment we run. You keep your existing phone numbers exactly as they are. We file the port requests, coordinate with your current carrier, schedule the port date around your business, and test thoroughly before the switch. Typical timeline: 5 to 10 business days.

Will VoIP work if our internet goes down?

A pure cloud-hosted PBX needs internet to function. The mitigations: (1) a quality firewall with WAN failover to a backup connection keeps you on-air for short outages, (2) automatic call forwarding to mobile devices kicks in instantly if the main internet drops, (3) SIP trunks support call rerouting so inbound calls hit a backup destination when your office is offline.

Can we integrate VoIP with Microsoft Teams?

Yes. We deploy Microsoft Teams Direct Routing via Sangoma's certified SBC service. Users keep Teams as their main interface for calls, but they are placing real PSTN calls through your Sangoma infrastructure with full PBX features (auto attendants, queues, recording) in the background.

Is VoIP HIPAA-compliant?

It can be, when configured properly. Maverick deploys VoIP for healthcare clients with: encrypted SIP signaling and SRTP media, BAAs in place with Sangoma, call recording stored encrypted with documented retention/destruction, role-based access to call logs and recordings, audit logging of all administrative actions.
