Siemens ISDX Maintenance

Siemens ISDX Telephone System

The ISDX product lifecycle was announced as end-of-sale by Siemens/Unify on 30th June 2016. The ISDX telephone system was a legend in itself; a production line so long (32 years) that it is a testament to the reliability of the product and the trust that British businesses still place upon it.

The ISDX telephone system may be end-of-sale, but it can still be maintained effectively.

ISDX Maintenance

Nexus IP have a clear understanding that ISDX owners might actually want to stay with their ISDX telephone system. Our approach is to simply ensure our clients are fully informed and allow them to make up their own minds on what action to take. We do not force our clients to upgrade or replace.
