Avaya Partner Phone System

The Avaya Partner Phone system is a great system to be used as a small business phone system. This system can enable up to 48 phones, caller ID, voicemail, and many other features. There are a variety of phones ranging from MLS 6 buttons that enable 4 lines all the way up to a MLS 34D that has a speaker and display. The Partner System can use either the Partner MLS Phones and/or the Partner (Euro style) Phones.

There are three kinds of Avaya Partner Phone Systems. There is the older AT&T Partner Plus phone system which will allow you one processor card, and four additional slots you can use for lines, phone stations, and/or voicemail. This was the original Partner phone system. The next one is the AT&T Partner II phone system which will allow you to expand to a second 5 slot carrier to add more lines and phone stations (the Partner Plus phone system is limited to one 5 slot carrier). Finally, there is the more recent Avaya Partner ACS system. These systems can also be called AT&T Partner and Lucent Partner.

The Avaya Partner ACS Business Phone System starts with the processor which has three incoming lines and eight phone stations built in. In the Partner Plus and Partner II phone systems the processors are just the brain of the system but you need to add on 206 modules to provide incoming lines and phone stations. The Avaya Partner ACS System can be expanded by adding on 206E, 206EC, and/or 308EC expansion modules. The Avaya Partner ACS system is also limited to a 5 slot carrier, but can provide 15 lines and up to 40 phones.
