SIP - Session Initiation Protocol A key technology in the convergence of voice and data is Session Initiation Protocol (SIP), which Aastra IntelliGate supports for trunk access as well as for the user connection. SIP trunks offer an alternative to digital or analogue trunk lines, and provide a number of key services previously unavailable. For example, using SIP trunks, you can set up a virtual "presence". This means that a company can have telephone numbers for incoming and outgoing calls on local exchanges without having a physical presence there. Using SIP, customers can also cost effectively port existing number ranges when moving from one exchange to another (ie relocation of offices). Aastra 6739i Linking up individual terminals via SIP Fax over the data network In addition to the high-performance Office terminals you can also connect SIP terminals from Aastra or other manufacturers. Aastra SIP terminals, which feature an elegant design, hands-free operation, conference circuit and a headset socket, also support the state-of-the-art XML standard. This allows information services to be indicated separately on the generous display. WLAN and Dual Mode (GSM/WLAN) terminals can also be logged on to using SIP and then integrated into the company network. Apart from speech, corporate data networks can also be used for fax transmissions, which allows you to benefit from the free transmission of faxes between your various locations. Reliable, real-time fax transfer is guaranteed by the use of the international standard T.38 protocol. Fax transmission via data network functions faultlessly with both analogue and digital fax machines. Making use of video telephony via the data network With modern SIP technology, it's all possible - experience your call partner live in high resolution video quality using video telephony. SIP trunks offer cost savings and user flexibility. 6
