PSTN | CT Wholesale

Reliable, versatile voice services

Traditional telephone lines are still a core communication medium and have a vital role to play alongside next generation technologies. Many businesses have this type of line for normal office business calls, faxes, EFTPOS lines, alarm and emergency lines.

A range of call handling features such as line hut and message bank and diversion are available to help optimise how your customers manage both incoming and outgoing calls.
