The basic system consists of one antenna and one BDU. Separate purchase of standard items including
POTS phones, SIP phones, computers, etc. may be needed. A modem can be connected to the WAN port for
data at least-cost routing operations. Voice calls are always routed through the Iridium system unless using a
data call application.
For your satellite communication system to work properly, c

ing to the conguration below.
6.6.1 Data sessions and voice calls
The System provides up to High-quality voice calls, multiple data sessions, Wi-Fi, and supports up to 18 ex-
tensions (including 2 analog phones and 16 sip phones).
The BDU communicates directly with SIP phones on any of the three LAN user ports (LAN 1, 2, 3, or 4). The
SIP phones register directly to the SIP server in the BDU.
