All of our On-Premise Telephone Systems are hybrid, which means they work with all types of traditional lines such as Analogue and ISDN as well as the latest line type SIP trunks. Hybrid systems also allow a mixture of analogue, digital and IP devices. You can either buy the on-premise system outright or lease rent the system over a fixed period of time for a set cost.
