AASTRA A1755-0131-10-55 6755i IP phone with power adapter.

The AASTRA A1755-0131-10-55 is the Aastra 6755i, a business-class SIP telephone designed for enterprise IP telephony deployments. This is a feature-rich desktop handset with a large graphical display, multiple programmable keys, and support for several concurrent SIP lines. This listing includes the power adapter.

The 6755i was designed for use in SIP-based unified communications environments, offering users an intuitive interface with soft keys, a high-resolution display, and support for advanced call handling features. It integrates with Aastra and third-party SIP platforms for professional voice communications.

This handset is part of the legacy Aastra 6700i series, which predates the Mitel acquisition. While discontinued, the 6755i remains deployed in many existing installations and is sought after for spares and system expansion where maintaining a consistent user experience is required.
