an acceptable IP address for both lines. To
enable the Restrict Source IP feature, select yes.
Otherwise, select no. If configured, the ATA will
drop all packets sent to its SIP Ports originated
from an untrusted IP address. A source IP
address is untrusted if it does not match any of
the IP addresses resolved from the configured
Proxy (or Outbound Proxy if Use Outbound Proxy
is yes) Default setting: no.

incoming INVITE requests from the SIP proxy.
