Cloud-based Voice with SIP Trunking
Extend your phone system to the cloud through SIP Trunking for more efficient and cost-effective Voice.
What is SIP Trunking?
SIP Trunking allows you to expand your existing phone system by running Voice over an internet connection.
By implementing SIP Trunking, your business can benefit from the scalability of cloud communications and connect with customers worldwide over Voice.
Interconnecting your telephony system with Infobip over SIP Trunking allows you to operate globally at a much lower cost. Use numbers from all over the world and incoming calls will be forwarded over SIP to your existing phone system for ease of use.
How does SIP Trunking work?
Your existing PBX system allows you to connect with people internally and externally by connecting to a public switched telephone network.
Enabling SIP Trunking takes your existing PBX hardware and connects it through the cloud instead of to the traditional public network.
This is done using Voice over Internet Protocol (VoIP) which transmits a voice call over an IP network and allows you to connect to other devices, including phones, laptops and tablets.
SIP Trunking can be used for call setup, management and teardown and enables VoIP connectivity with your established PBX allowing you to connect with customers worldwide.
