Upgrade your Avaya SDX INDeX

Good Reasons to Upgrade your Avaya SDX INDeX?

Here’s why you should think seriously at upgrading your SDX / Avaya INDeX system:

You’re paying too much for SDX INDeX maintenance

Cost of Maintenance

Maintenance costs are usually high with SDX and Avaya INDeX telephone systems. So high in fact, that the cost of buying a completely new telephone system can be reconciled within three years.If you decide to lease your system over 3 or 5 years, you’ll reduce your phone system costs right away.

The cost of call-outs and INDeX ownership is getting too high

Cost of Ownership

Most modern phone systems can either be administered by your own in-house staff, or via remote diagnostics with fast turn-around times for alterations and re-programming. Modern phone systems need fewer call-outs and extra hardware such as phones and system cards cost far less than INDeX equipment and are easier to obtain.

You can communicate better with modern telecoms functionality

Improve Functionality

Modern phone systems with VoIP and CTI technology have many more user-friendly functions and applications available. As well as saving money, you can revolutionise the way your business communicates.

You shouldn’t have to search or wait for spares.

Spares Availability

Spares and replacement parts for the SDX and Avaya INDeX are now difficult to obtain, and cost much more than equivalent items for modern phone systems.

It shouldn’t be difficult to find someone to fix your phone system

Engineering Expertise

As the INDeX system gets older, expertise in supporting, maintaining and configuring it becomes more and more scarce. Response times rise and you pay a premium for services which are fewer and in higher demand.

Adding the latest technology shouldn’t cost the earth.

Latest Technology

The cost of adding the latest technology such as VoIP and Unified Messaging to the Avaya INDeX can often be as much as a complete new system, or worse may not be possible at all.

There should be a clear and easy path for upgrading

Expensive Upgrades

Upgrading the Avaya INDeX to support new protocols can also be difficult and costly, for example upgrading your ISDN30 DASS card to the new ISDN30E protocol.

Using and adding new technology should be easy.


All of our telephone systems are compatible with VoIP, CTI, SIP and other modern telecoms technologies and standards.
