    03Explained

    Hosted VoIP and SIP trunks, explained

    Hosted VoIP is a cloud phone system. Instead of a phone system box in a cupboard, your extensions, call routing, auto attendant, queues and voicemail run in the cloud, and staff take calls on desk phones, a computer or a mobile app. You pay per user (seat) each month.

    SIP trunks are the alternative when you already own a phone system (PBX) you want to keep. They connect that PBX to the phone network over your internet connection, replacing ISDN and analogue lines, which are being retired as part of the UK's move off the old copper telephone network.

    Both need a reliable business internet connection. OCCTA business broadband and leased lines are designed for voice, and we can quote the connection and phone system together.

    Questions

    How much does OCCTA hosted VoIP cost?
    From £6.95 per seat per month excluding VAT. SIP trunks start from £5.95 per trunk per month excluding VAT.
    Can I keep my business phone numbers?
    Yes. Existing geographic and non-geographic numbers can usually be ported to OCCTA.
    Do I need new phones?
    Not necessarily. Softphone apps work on computers and mobiles, and many existing SIP desk phones can be reused. We'll check during the quote.
