With it's roots going back to the Avaya / Lucent Legend telephone system, Partner Advanced Communication System (ACS) has grown into one of the most ubiquitous small-to-medium sized business telephone systems ever created. While you may encounter equipment for this system that is branded with Avaya, Lucent or AT&T, the underlying technology which makes the sysetm work is all the same.
Partner telephones are broken into three categories: the MLS Series were relased with the earliest versions of Partner; then the Euro Style of phone was released to expand on the popularity of those phones while maintaining some of the more popular phone models. With the release of the Second Generation / Gen 2 / Series 2 Partner phones, Avaya had locked itself into a product line that would find its way into small to medium sized businesses for decades - and are still found in service everywhere today.
For an in-depth look at the Partner ACS system and all the related phones you will find offered for sale, please see our blog post.
Here you will find MLS series interpsersed with Euro and Series 2 models; while they all enjoy the exact same functionality and compatibility, the differing models can offer buyers a wide range of cosmetic and budget options to fit any need.
