The Nortel Norstar M7100 telephone comes across as a base system that works 
best for lower functional zones like lobbies and recreation areas.
With a single programmable memory button and a feature button, a 16
character LCD display, message waiting indicator and a compatibility
with all Norstar integrated communication systems, it is worth buying for your enterprise. Moving over to a more improvised model, the Nortel Norstar M7324 has been crafted to provide connection of two central answering position modules, has 24 programmable but
tons, two-line display of 16 characters each line and is compatible with all Norstar integrated communication systems.
