Frequently asked questions
You have queries, we have answers
What Is SIP?
SIP (Session Initiation Protocol) is a technology used to establish, modify and eventually terminate connections between two or more VoIP participants—no matter where they are in the world. SIP lets you reap the advantages of VoIP such as reduced costs and minimal lags and downtimes.
What are SIP trunks used for?
While SIP trunks can have several applications, they are primarily used to facilitate Internet-enabled high quality voice calls.
Is SIP the same as VoIP?
VoIP is an umbrella term that refers to every Internet-based call. SIP trunking is a technology that connects traditional telephony devices to the Internet to enhance their functionality.
Do my agents need technical expertise to understand SIP?
Not at all. We provide simple set-up instructions and a user-friendly portal for day-to-day management. Our support representatives are also happy to walk you through configuration and get you up and running in no time.
