Connect the IP PBX to a SIP Trunk

For enterprises wanting to make full use of their installed IP-PBXs and not only communicate over IP within the enterprise, but also outside the enterprise the Ingate SIP Trunking module offers an easy and smooth transition to a modern and future-proofed SIP trunk provided by an Internet Telephony Service Provider to connect to the traditional PSTN network. SIP trunks can offer significant cost-savings for enterprises, eliminating the need for local PSTN gateways, costly ISDN BRIs (Basic Rate Interfaces) or PRIs (Primary Rate Interfaces).

What is a SIP Trunk?

SIP trunking is a service which permits businesses to adopt Voice-over-IP (VoIP) using the same connection as the Internet connection and remain in touch with others who rely on the PSTN as the enterprise IP-PBX is connected to the service provider’s PSTN gateways over the Internet.
