For example, you can designate that calls to and from specific countries go over the SIP trunk. Now Zoom can intelligently control which calls will traverse the SIP trunk, and can support call-out to internal extension-only phones. We can easily combine SIP-connected audio with Zoom PSTN dial-in and call-out services in order to cover all your phone users around the globe. Zoom is very flexible in our support for SIP-connected audio.
This connection is secure and reliable, and saves money compared to PSTN rates and fees. Meeting participants that dial into a meeting or have the meeting call them, and are “on net” from the perspective of the customers IP telephony network, will be connected over this trunk rather than over the Public Switched Telephone Network (PSTN aka phone lines). With SIP-connected audio, we establish a SIP trunk (a network connection specifically designed to make and deliver phone calls) over a direct and private connection between the customer’s network and the Zoom cloud. It is intended for our larger customers that have a significant on-premise IP telephony deployment and do more than a million minutes of conferencing every month. SIP-connected audio is a highly cost-effective solution for enabling telephone users to participate in Zoom meetings and can directly help enterprises reduce or optimize their audio spend. Zoom is excited to announce improved support for SIP-connected audio.
