Features

• XML Browser

Create internal service applications using development guides available from Aastra. This feature provides unlimited potential to customize the Aastra 6755i to meet your specific business needs or vertical applications using the display and keypad.

• Enhanced Call Management
  With extensive storage capacity for personal directories, callers logs and redial lists and 12 programable keys, the Aastra 6755i can improve efficiency by providing more call information with the push of a button. Features such as shared call and bridged line appearances, call forward, call transfer, call waiting, intercom and local 3-way conference increase call flexibility and control.

• Expandability
  The Aastra 6755i supports up to three Aastra M670i modules, each offering 36 keys with LED indicators to create a feature rich attendant console.

• Remarkable Audio
  All 67xi Series IP Telephones offer full-duplex speakerphones. With the addition of our wideband audio technology, Aastra Hi-Q™, Aastra SIP phones now deliver enhanced audio performance and superior voice clarity.

• Simplified Deployment
  From initial deployment and configuration to future enhancements and upgrades, the Aastra family of IP telephones are designed to save your business time and money. Dual auto-sensing switched Ethernet ports eliminate additional wiring and simplify installations. Integrated IEEE 802.3af Power-over-Ethernet allows easy deployment with centralized powering and backup. Easily created configuration files, using any text editor, can be used to configure phones individually or centrally.
