When you need modern Voice over Internet Protocol (VoIP) services for your businesses, you’ll find that some providers are better choices than others. Choosing a provider involves looking at the services, features, and cost. However, if you already have a phone system at your business, you can get the same VoIP features by adding Session Initiation Protocol (SIP).
SIP trunking gives organizations features like voice, messaging, and connectivity using private branch exchange (PBX). The system relies on infrastructure used for landlines. Businesses can also turn to cloud-based SIP trunking for more services through the internet.
The services include voice calling through the internet for remote and on-site workers. It also includes robust video conferencing, chat messaging, and file transfer services. Another benefit of SIP trunking includes multitasking through the phone service, as it can handle up to 20 calls at once.
These five providers are the best choices for businesses looking to use SIP trunks for phone services:
