Key terms in plain language
Open a term for a concise explanation of language used on this page.
VoIP
Voice over Internet Protocol carries phone calls over an IP network instead of a traditional analog phone line. Call quality depends on network stability, latency, and traffic management.
Unified Communications (UCaaS)
A cloud-based combination of business calling, messaging, meetings, presence, and collaboration tools managed as one communications service.
SIP Trunking
A service that connects a business phone system to the public telephone network using Internet Protocol, replacing or supplementing traditional phone lines.
Bandwidth
The amount of data a connection can carry in a given time, usually measured in Mbps or Gbps. More bandwidth supports more users, devices, and simultaneous applications.
Latency
The time it takes data to travel between two points. Lower latency improves voice, video meetings, cloud applications, gaming, and other real-time services.
Service-Level Agreement (SLA)
A provider’s written commitment covering service targets such as availability, response time, repair time, and sometimes financial credits when commitments are missed.
