Our SIP Trunking / SIP Trunk VoIP telephone lines are available for use with the majority of VoIP enabled PBX Telephone Systems.

Our SIP Trunking services are available for only £2.00 per month rental, with low cost call rates and a high quality service. SIP Trunks are quick and simple to set up and with lower installation and start up costs compared to traditional analogue and ISDN telephone lines they are a great choice for businesses who want to take advantage of modern communication technologies.
GET THE MOST FROM YOUR IP PBX
Businesses that have recently installed or upgraded their phone system will be aware of it’s VoIP capability and will want to make some or full use of the VoIP capability and not only communicate over IP within the enterprise, but also outside the enterprise. A SIP trunk provided by an Internet Telephony Service Provider to connect to the traditional PSTN network is the solution.
Unlike traditional telephony, where bundles of physical wires were once delivered from the service provider to a business, SIP trunking allows a company to replace these traditional fixed PSTN lines with PSTN connectivity via a SIP trunk service provider using the Internet to provide the link between the phone system and the telephone network.
