Aastra 5000 is an open standards-based system and, thus, an IP telephony application fully integrated into the information system.
Natively IP and SIP-oriented, Aastra 5000 is compatible with any terminal type: Aastra IP, SIP, video SIP, H323, IP DECT, Wi-Fi SIP or GSM/Wi-Fi, SIP or Aastra soft-phones.
The Aastra 5000 software can interface with analogue and digital terminals, or traditional DECT sets via Aastra X Series gateways.
Aastra 5000 has a SIP Trunk interface that enables connection to Voice over IP providers (operators).
Thanks to its networking capacity, Aastra 5000 can manage up to 150,000 subscribers and 2,000 sites.
System administration is performed remotely using a simple web browser. Secure and ergonomic, it is standards-based: https for secure access, LDAP for the integrated directory which can be synchronised with a company directory, and SNMP for system supervision.
Security is guaranteed at several levels. For critical subscribers, the software allows voice and signalling encryption, without additional hardware.
The quality of IP calls is enhanced by the use of a direct voice architecture (end-to-end voice over IP), flow prioritisation (802.1p/q, Tos marking), and dynamic adaptation to the IP network occupation status (Call Admission Control).
Aastra 5000 is one of the most comprehensive software applications on the market, with over 500 functions.
Aastra 5000 also interacts with unified messaging applications (UCP, Microsoft Exchange, IBM Lotus Notes) and collaborative tools (TWP, MOCS, IBM Sametime).
