    The Mitel (Aastra) 6755i (55i) IP Phone includes the following features:

    XML Support
    The Mitel (Aastra) 6755i is equipped with XML browser capabilities allowing access to customized services and applications. Create internal service applications using development guides available from Mitel (Aastra). This feature provides unlimited potential to customize the Mitel (Aastra) 6755i to meet your specific business needs or vertical and CTI applications using the display and keypad

    Enhanced Call Management
    With extensive storage capacity for personal directories, callers logs and redial lists, the Mitel (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

    The Mitel (Aastra) 6755i supports up to three Mitel (Aastra) 536M modules, each offering 36 keys with LED indicators to create a feature rich attendant console

    Remarkable Audio
    The Mitel (Aastra) 6755i IP telephones offer full-duplex speakerphone for excellent voice clarity and delivery. With the addition of wide-band audio sound* and our over 15 years experience in telecommunications and telephone design, Mitel (Aastra) can ensure superior voice quality on every product we sell

    Simplified Deployment
    From initial deployment and configuration to future enhancements and upgrades, the Mitel (Aastra) 6755i is designed to save your business time and money. Easily created configuration files, using any text editor and a variety of communication protocols, can be used to configure phones individually or centrally.

    For users who make extensive use of the phone for business calls, the Mitel (Aastra) 6755i fits the bill. Offering a wide range of features, this model is clearly ahead of the pack. With expansion capabilities that do not hurt the budget, the Mitel (Aastra) 6755i is truly in a class of its own

    One nice feature of the Mitel (Aastra) 6755i is its compatibility with different SIP platforms. It can integrate and work seamlessly on platforms like Asterisk and Trixbox. This is made possible with the use of the built in advanced XML capabilities, providing means of customising virtually unlimited applications. With the use of development guides that are provided by Mitel (Aastra), it is possible to create internal service applications that will enable the user to customise according to specific business needs. This feature alone presents a potential that is so wide that it may be able to meet any specific needs of the business

    If that is not enough, the Mitel (Aastra) 6755i is also designed to handle and manage up to nine calls simultaneously, each with individual call appearances. There are also up to 6 soft keys that can be customised and programmed for up to 20 distinct functions. Aside from these keys, there are 8 dedicated ones for handling functions as call redial, call on hold, toggling between speakerphone and headset, call muting, "Goodbye" feature, and volume adjust keys

    The Mitel (Aastra) 6755i has two 10/100 Mbps Ethernet ports for flexible network connectivity. IP addressing can be configured manually or through the use of DHCP. DHCP options covers a wide selection as well, including 66, 60, 43, 77, 159 and 160. Synchronising date and time is made possible through SNTP. Remote configuration, deployment and management is possible as well through FTP or TFTP

    With Mitel (Aastra)'s propriety Hi-Q wideband audio technology, every call made provides a rich, life-like talk experience. The phone even has support for different means of communication, such as the use of headset or the speakerphone for complete hands-off operation

    For enterprise application that demands more for future expansion, the Mitel (Aastra) 6755i can support up to 3 modules, further boosting its already feature rich features. This is actually a cost efficient means of extending the functionality of the IP Phone because there is no need to purchase additional IP Phones at the moment, while at the same time these expansion modules cost considerably lesser than a phone
