Transport
Server Expires
Keep Alive Interval
Description
Specify the transport protocol
for transmitting the SIP
signaling.
The supported protocols are
as follows:
UDP—it provides the
•
best transmission for SIP
signaling.
•
TCP—it provides a reliable
transmission for SIP
signaling.
TLS—it provides a safe
•
transmission for SIP
signaling. TLS is available
only when the device is
registered on a SIP server
that supports TLS.
•
DNS-NAPTR—the device
performs the DNS NAPTR
and SRV request to find
the service type and the
port if no server port is
given.
Default: UDP.
The registration timeout (in
seconds) of the device.
After the timeout, the device
will send the registration
request to the SIP server
again.
Default: 3600 seconds.
Configure the interval (in
seconds) that the device
sends keep-alive messages
to the SIP server, so that
the SIP server can remain
connected to the device.
Default: 30 seconds.
