SIP (Session Initiation Protocol) Trunk Providers are companies that offer a service allowing businesses to make phone calls over the internet instead of traditional phone lines. SIP trunks are used to connect a company's phone system to the Public Switched Telephone Network (PSTN) and can provide cost savings and scalability.
Session Initiation Protocol (SIP) Trunking is a communication technology that enables users to make and receive phone calls, as well as transmit other digital media over the Internet for real-time interactions. Here’s how it works:
- What Is SIP Trunking?
SIP Trunking supports cloud-based communications like voice over IP (VoIP) telephony, SMS texting, video conferencing, and messaging.
It uses Session Initiation Protocol (SIP) to establish connections between endpoints, allowing users to stream data back and forth.
A SIP Trunk is a virtual phone line, not a physical device.
Businesses, residences, and individual users can use SIP Trunking from their choice of several endpoints: mobile applications, desktop-based softphones, or an on-premise phone system with physical VoIP and SIP-compatible phones.
- How SIP Trunking Works:
Instead of traditional copper phone lines, SIP Trunking uses virtual SIP channels to connect users’ devices (called “endpoints”).
These endpoints can be mobile apps, softphones, or physical VoIP phones.
SIP Trunking allows users to stream VoIP calls, video conferencing, and messaging over the internet.
- Choosing a SIP Trunking Provider:
When selecting a SIP Trunking provider, consider factors such as feature highlights, reliability, uptime, network capacity, disaster recovery, migration, and pricing.
