We have a huge directory of buyers who may be interested in your used Aastra IP phones, SIP phones, and digital phone systems so contact us today for a free quote.

Sell All of Your Used Aastra Phones in a Single Transaction 

Liquid Technology’s liquidation services conveniently process your entire inventory in a single, smooth transaction. Rather than leave you with certain pieces of equipment, like some liquidators are apt to do, we purchase all makes and models so your liquidation is complete. If it is determined that some of your equipment is not operable or financially obsolete, then we will dispose and recycle the equipment in the most environmentally-responsible manner to eliminate risk to your company.
