What are Cloud SIP Providers
Cloud SIP providers offer Session Initiation Protocol (SIP) trunking services hosted in the cloud. This enables businesses to make and receive phone calls over the internet without relying on traditional phone lines or on-premise PBX hardware.
A cloud SIP provider delivers voice services via a virtual SIP trunk that connects your phone system to the Public Switched Telephone Network (PSTN), enhancing scalability, reducing costs, and enabling remote accessibility.
Why Do Businesses Choose Cloud-Based SIP Trunking
1. Cost-Effective Communication
Cloud SIP trunking helps reduce costs by replacing traditional fixed lines with a virtual, internet-based connection. At NFON, we offer predictable pricing models and scalable services to suit organizations of all sizes.
2. Scalability on Demand
With NFON, businesses can scale their SIP channels as needed. Our solution allows you to add or remove concurrent call paths quickly and easily via the customer portal.
3. Local Numbers for Global Presence
NFON offers local and international telephone numbers in many European markets. This enables businesses to establish a regional presence without opening physical offices.
4. Redundancy & High Availability
Our SIP infrastructure is hosted in geo-redundant data centers, supporting a high service availability. Failover mechanisms help ensure business continuity.
5. Compatible with Microsoft Teams & CRM
NFON SIP Trunks can be integrated with Microsoft Teams via Direct Routing. Additional integration options are available depending on customer setup and requirements, including selected CRM systems.
6. Smooth Transition from Legacy Systems
Whether you are running a legacy PBX or planning to move to a full cloud solution, NFON SIP Trunking can serve as a flexible bridge for your migration.
SIP Trunking for SMBs and Remote Teams
Small and medium-sized businesses benefit from the flexibility and affordability of cloud SIP trunking. NFON supports remote teams by enabling location-independent telephony with softphones, mobile apps, and secure VoIP trunking: ideal for hybrid or distributed work environments.
SIP Trunking vs. VoIP: What’s the Difference?
SIP trunking is a method of delivering voice services over the internet using it’s own protocol, while VoIP refers more broadly to any voice transmission via IP. SIP trunking specifically connects PBX systems to the phone network, whereas VoIP can include app-based calling platforms.
Businesses seeking a scalable solution often opt for SIP trunking for its enterprise-level control and compatibility with existing infrastructure.
