❓ Frequently Asked Questions
❓ Is the Aastra 470 compatible with IP telephony and SIP phones?
Yes, the Aastra 470 IPBX server natively supports VoIP and the SIP protocol, allowing it to integrate IP phones, softphones, or SIP trunks. It also ensures coexistence with traditional telephone installations (ISDN, analog), facilitating gradual migration to IP telephony while retaining the existing infrastructure.
❓ How many users can this business telephony system support?
The Aastra 470 PBX is sized for medium-sized businesses. With the 4 modules included in this lot (8DSI + 16DSI + 4FXS + 8BRI), the system can connect up to 24 digital DSI extensions, 4 analog devices (phone, fax, modem), and 8 ISDN BRI lines, providing a complete multi-line telephone system ready to use.
❓ Does the Mitel MiVoice 470 server fit in a standard rack cabinet?
Yes, the Aastra 470 chassis is designed for installation in a 19-inch rack thanks to the included mounting bracket in this lot. It can also be placed on a flat surface. This mounting flexibility makes it an ideal telephone switch for server rooms, patch panels, or network cabinets.
❓ Are the DSI, FXS, and BRI modules all tested and functional?
Yes, the entire lot — the Aastra 470 server and the 4 interface modules (8DSI, 4FXS, 16DSI, 8BRI) — is sold as tested and fully functional used equipment. Each item is checked before shipping. A 30-day warranty covers any hardware defects found upon receipt. If you have questions about the condition of a specific component, please contact us before purchase.
❓ Can this IPBX be interconnected with other sites via IP network or VPN?
Absolutely. The Aastra 470 is part of the Aastra 400 / MiVoice Office 400 range, a platform designed for multi-site telephony. It is possible to interconnect multiple servers via LAN/WAN or VPN, allowing for inter-site short dialing, a unified numbering plan, and shared voice resources. Ideal for companies with multiple branches or remote offices.
