No.  Those devices could be connected via V.35 serial port or IP.  If 
using IP over ADSL, there'd be a router that connected to the ADSL 
line.  The router would be configured to provided an IPSec VPN between 
sites.  I have also used IP over fibre, microwave and SHDSL, where those 
devices were simply an ethernet bridge.  The serial port is used to 
connect via ISDN, using an ISU or fractional T1, using a TSU, or 
sometimes via a TDM multiplexer with a V.35 card.  Depending on the 
model, they could handle up to 24 extensions.  The bandwidth required 
depended on the compression used.  They used a proprietary protocol and 
not SIP.
