Frequently asked questions

SIP trunking is a method of delivering voice and other unified communications services over the internet or a dedicated IP network. It replaces traditional analog or digital telephone lines with a virtual connection.

SIP trunking works by using the SIP protocol to establish, manage, and terminate voice, video, and messaging sessions over an IP network. It connects an organization’s PBX to the service provider’s network, allowing for the transmission of voice and data traffic.

Some benefits of SIP trunking include cost savings, scalability, flexibility, improved disaster recovery, and the ability to consolidate voice and data traffic over a single network connection.

No, SIP trunking and VoIP are related but not the same. VoIP (Voice over Internet Protocol) refers to the technology that allows voice communication over the internet. SIP trunking is a specific implementation of VoIP that connects an organization’s PBX to the PSTN or an ITSP.

To set up SIP trunking, you will need an IP-enabled PBX system and a reliable internet connection. You may also need a session border controller (SBC) for security and network management.
