PBX and PBX maintenance

A PBX (Private Branch Exchange) connects internal office users and enables them to dial each other direct, or to dial external calls over a private network or across the telephony network (PSTN).

O2’s PBX maintenance is tailored to meet your requirements. We deliver hardware, breadth of service and fast and efficient fault repair.

"We have been fortunate over the past 5 years to work with an evolving O2 account team who have continued to deliver enhanced service requirements."
