What Can IP Voice Multi-Line Do?

IP Voice Multi-Line connects IP voice to your existing telephone systems. Your Multi-Line service can have several ‘Trunks’ which connect your PBX to Telair. You allocate the number of channels available on your Multi-Line and these can be used dynamically across all your trunks. The number of channels is the number of concurrent calls you can make. If you go over your channel limit Telair will still allow you to make and receive calls, ensuring you never miss a call.
