What is SIP trunking?
SIP (session initiation protocol) is a type of VoIP (voice over Internet protocol) standard that allows you to run and manage voice, video and messaging ‘sessions’ digitally. SIP trunking connects your private branch exchange (PBX) to the Internet, like a digital version of a landline. It’s becoming the industry standard for enterprise VoIP calling.
Whether set up on premises or hosted virtually, SIP trunks can hold huge numbers of lines – called channels – to connect your users via any enabled desktop or mobile device.
Choose future-ready, flexible calling with a SIP trunk service
Telephony is a critical part of how service-driven organisations communicate with customers. A reliable phone system is therefore fundamental if you’re to deliver the level of customer service you promise.
But older technologies can be expensive and time-consuming to maintain, reconfigure and move. If you’re expanding, downsizing or setting up services in new countries, traditional phone systems can slow down your progress.
SIP trunking is the ideal solution if you’re looking to move from an analogue PBX to an IP version. There’s no need to switch carriers and, if you’re using cloud-based SIP trunking, there’s no huge capital outlay on new equipment required. But it’s also a choice move if you’re communicating digitally via ISDN, which is to be phased out in the UK by 2025.
All media, all locations
SIP trunking gives you one line for voice, instant messaging and video, making it the perfect underpinning technology for unified communications and collaboration. Your services will be available to users and customers in any location, on any device.
