The Ericsson Md110 has been around for a significant amount of time, and at one point had one of the largest market shares of the PBX sector. It's modular design, reliability and ability to interwork with many other systems and services meant it was the perfect enterprise telephony solution. In the late 1990s Ericsson sold it's PBX business to Canadian firm, Aastra. Aastra carried on the development of the platform under the MX-One model designation, converting it to a Linux server based architecture and native SIP operability, giving a perfect migration path from the old digital platform. Aastra was ultimately bought by Mitel, but the platform was so strong they continued with it as a large enterprise telephony solution. To this day there are still Md110 platforms that are quietly chugging away providing telephony services to businesses around the globe.
One of the requirements of an on-premises telephone system is that it needs to be looked after. In a hosted environment this all takes part behind the scenes, but when it's physically in your office building you are responsible for it. Simple things from adds, moves and changes, to replacement parts, additional line cards and complex fault finding, need to be carried out by an engineer. In some cases this can be done remotely through a modem connection or a VPN, in other cases a site visit may be required. Although the Md110 and MX-One are incredibly reliable, some of the older systems will start to suffer from hardware failure.
We have been working with the Md110 and MX-One platforms for nearly 25 years. If you need to discuss your system, the options for the future, or just to provide some ad-hoc support, we can help you! There aren't very many Ericsson equipment maintainers left, and most of them won't look at older versions. But, we will. We can't guarantee we can keep them running forever, but we can help you work out a strategy for replacement, and provide maintenance cover in the interim.
