Connect your VoIP PBX to the telephone network
SIP (Session Initiation Protocol) trunking lets your business phone system use an internet connection instead of a traditional phone line, for both local and toll-free numbers. Each SIP trunk supports a number of channels, and the number of channels sets how many calls can be active at once.
Our SIP trunks connect your site directly into our network over IP to carry and terminate inbound and outbound calls across the public telephone network. SIP is rapidly replacing traditional ISDN and PSTN services: it costs less, scales more easily and is more reliable.
