Avaya Partner 18D Phone Series 1

The Avaya Partner 18D Series 1 phone was the original Partner phone for the ACS phone systems. This phone replaced the MLS style phones and has since been replaced with the Series 2 Partner 18D.

The only real difference between the two is physical styling and age.
