Mitel has announced that from December 1st 2018 it will increase its prices for the 5300 Series IP Phones. Through 2018, Mitel has seen a transition in their IP Phone sales to the 6900 Series IP Phones. With that increase, sales of 5300 IP Phone models have declined in all regions. That decline has resulted in higher manufacturing costs due as Mitel lose economies of scale in production. 

To offset these commercial challenges, a price increase of roughly 10% (depending on currency) to all 5300 series IP Phones is being introduced. The new prices are effective from December 1st 2018.
