Legacy PBX Maintenance & Migration

Buy your existing system some time whilst you plan your move to cloud. Get full value from your expensive contact centre solution. Avoid paying again for a compliant call recording solution.

Extending the life of your existing phone system often makes sound business sense.

But it can raise many questions. Is the system still supported by the manufacturer? Can is still get spare parts? Will any of my system work on a new platform?
One2Call can help.

We’ll keep your existing systems running and help you plan for the future. Our fixed fee maintenance contracts can include phone systems, call recorders and hospitality.

      Planning PBX Transition

      Planning your PBX Transition

      If you’re using an on-premise phone system, now is the time to start working with us on a transition plan. As analogue and ISDN services become end-of-life (EOL) we expect on-site PBXs to go the same way.

      By working with us now we can make this transition smoother and less costly. In most cases we’ll upgrade your technology and save you money. Our experienced consultants will work with you on a transition plan designed around your needs.

      You should start your transition planning now if you’re running one of the following PBX phone systems:

      • Alcatel-Lucent
      • Avaya IP Office
      • Ericsson-LG IPECS

      Maintaining Call Recording Systems

      Call Recording solutions are often third-party add-ons to the main system. This may mean they can continue in use even if your phone system is end-of-life.

      This is particularly worth investigating if you use a compliance call recorder. Regulation like PCI-DSS, MIFID and GDPR made many businesses upgrade their call recorder. We can investigate saving your investment by moving it to a new voice platform. If you just want to keep your call recorder running as long as possible, we can help with that too.

      However, if you are using any of the following Call Recorders we recommend reviewing your options:

      Legacy Call Recorders
      • Akixi
      • Commsoft
      • Oak
      • TIM plus

      Speed of response and excellent customer service, we like working with smaller local suppliers rather than faceless national providers for these reasons.
