For users who make extensive use of the phone for business calls, the 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 Aastra 6755i is truly in a class of its own

One nice feature of the 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 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 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 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 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 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
