What is FluidOne’s solution for Landline?

We supply single and multi-line PSTN (Public Switched Telephone Network) services for use with traditional PBX, fax systems, lift and alarm monitoring solutions; as well as for DSL and FTTC broadband services. We also have a range of care levels tailored to your fault repair requirements.

Our PSTN/ISDN services allow you to connect any size of traditional PBX system, with the advantage of feature-rich capabilities, such as DDI’s (Direct Dial-In’s).

FluidOne offers reliable products that deliver the best performance. It is a premium service, and it means we can provide our clients with a consistently strong and efficient service.
