What does that say?
Plain Old Telephone Lines are
Analog Telephone Trunks
(POTS) - Each of these
telephone Lines or trunk
connects directly from the
telephone line provider to the
X-50 system.
Unlike analog trunks, SIP trunks do not physically connect to the X-
50 VoIP Telephone System. Each SIP trunk is assigned a special
authentication ID and Password, that systemically connects them
from the SIP Telephone Line provider to the X-50 VoIP Telephone
System using the broadband (Internet) Connection. Once
programmed, the X-50 system and the SIP trunks remain
“connected” and are accessed just like an analog trunk.
Because SIP Trunks are accessed through the broadband (Internet)
connection it is important that there is enough bandwidth. Contact
the ISP to ensure that the bandwidth is a is sufficient to handle the
SIP Trunk Requirements. It is suggested that a minimum of 7meg up
and 1 meg down, known as 7 x 1, should be enough.
