ADAPTION
Disabled
To ensure all SIP messages go directly to the NAT gateway in
the SIP aware router.
If the system receives a SIP response to a REGISTER request
with a “Via” header that includes the “received” parameter
(ex: “Via: SIP/2.0/UDP 10.1.1.1:4540;received=68.44.20.1”),
the base will adapt its contact information to the IP address
from the “received” parameter. Thus, the base will issue
another REGISTER request with the updated contact
information.
If NAT Adaption is disabled, the “received” parameter is
ignored.
