Cloud PBX Hub FAQ
How do I set up a cloud call center?
You can deploy a call center using PortaSwitch and cloud PBX in under nine minutes. Watch our quick setup tutorial, or explore the Call Center Software overview.
What’s the difference between cloud PBX and on-premise PBX?
Cloud PBX is managed off-site in the cloud and requires no physical infrastructure. On-premise PBX systems need hardware, ongoing maintenance, and dedicated IT teams. Cloud PBX is more scalable and cost-effective.
Can I customize the cloud PBX with my own branding?
Yes! With the PortaOne suite of white-label tools, such as PortaPhone and the mobile self-care app, you can fully customize apps and portals with your brand’s name, logo, and colors.
What are the key features of the PortaOne cloud PBX platform?
PortaOne’s cloud PBX runs on PortaSwitch, which combines Class 4 carrier routing and Class 5 subscriber features in one softswitch with billing, provisioning and reseller management. Features group into five areas.
Integrations and API. Open REST API, CRM connectors (Salesforce, HubSpot, Zoho, Zendesk, Freshdesk), Microsoft Teams Direct Routing, accounting and payments (Xero, QuickBooks, Stripe), webhooks and event feeds.
One platform, many business customers. Isolated tenants per business customer, reseller and dealer hierarchies with their own branding and pricing, white-label self-care portals at every level, auto-provisioning of IP phones, bulk extension and number management.
Call handling. IVR and auto attendant, hunt groups, call queues and ring groups, transfer, parking, pickup, barge-in and supervision, call recording with export, business-hour and holiday routing, conference bridges, video calling.
Self-service. End-user portal for voicemail, forwarding and devices, an admin portal per business customer, the PortaPhone softphone on mobile and web, presence and BLF, voicemail to email.
Carrier grade. Geo-redundant sites with failover, 99.999% availability, fraud and toll-abuse controls, real-time charging per call, and capacity sized on concurrent calls rather than per-seat licences.
AI voice agents, speech-to-text and text-to-speech are optional modules, priced separately, with a 30-day trial.
Are there real examples of businesses using PortaOne for cloud PBX?
Yes! Companies like Kalaam Telecom, Vanilla Telecoms, and Virtual Call use PortaSwitch to deliver reliable hosted PBX and call center services.
Can I integrate cloud PBX with CRMs or other systems?
Absolutely. You can embed voice calling into CRM platforms, enable omnichannel messaging, and automate customer service using solutions like PortaPhone and HELIOS. See how it works in this video and this CRM integration case.
Does PortaSwitch support multitenancy?
Yes. PortaSwitch allows you to host multiple virtual PBX systems for different business customers on the same platform. Each customer can have their own extensions, call routing, IVR, branding, and usage limits — all fully isolated but centrally managed. This makes it easy for telecom providers to scale their cloud PBX services and support hundreds or thousands of business clients efficiently.
Is high availability supported?
Yes. PortaSwitch is designed for high availability and redundancy. It includes built-in failover mechanisms, real-time replication, and load balancing to ensure uninterrupted service even during maintenance or infrastructure issues.
Does PortaSwitch support real-time billing?
Yes. Real-time convergent billing is one of PortaSwitch’s core strengths. It enables instant rating, charging, and balance control across voice, data, short message service (SMS), and other services. With PortaSwitch, telecom providers can offer flexible prepaid and postpaid plans, enforce credit limits, and bill usage as it happens — with no delays.
