Note: This registration header is according to the IMS 3GPP
TS24.229 and PKT-SP-24.220 specifications.

[InitialRouteHeader]
Enables the inclusion of the SIP Route header in initial
registration or re-registration (REGISTER) requests sent by the
device.
[0] Disable (default)
[1] Enable
When the device sends a REGISTER message, the Route
header includes either the Proxy's FQDN, or IP address and port
according to the configured Proxy Set, for example:
Route: <sip:10.10.10.10;lr;transport=udp>
or
Route: <sip: pcscf-
gm.ims.rr.com;lr;transport=udp>
configure voip > sip-definition
settings > ping-pong-keep-alive
[UsePingPongKeepAlive]
Enables the use of the carriage-return and line-feed sequences
(CRLF) Keep-Alive mechanism, according to RFC 5626
“Managing Client-Initiated Connections in the Session Initiation
Protocol (SIP)” for reliable, connection-orientated transport types
such as TCP.
[0] Disable (default)
[1] Enable
The SIP user agent/client (i.e., device) uses a simple periodic
message as a keep-alive mechanism to keep their flow to the
proxy or registrar alive (used for example, to keep NAT bindings
open). For connection-oriented transports such as TCP/TLS this
is based on CRLF. This mechanism uses a client-to-server "ping"
keep-alive and a corresponding server-to-client "pong" message.
This ping-pong sequence allows the client, and optionally the
server, to tell if its flow is still active and useful for SIP traffic. If
the client does not receive a pong in response to its ping, it
declares the flow “dead” and opens a new flow in its place. In the
CRLF Keep-Alive mechanism the client periodically (defined by
the PingPongKeepAliveTime parameter) sends a double-CRLF
(the "ping") then waits to receive a single CRLF (the "pong"). If
the client does not receive a "pong" within an appropriate amount
of time, it considers the flow failed.
Note: The device sends a CRLF message to the Proxy Set only if
the Proxy Keep-Alive feature (EnableProxyKeepAlive parameter)
is enabled and its transport type is set to TCP or TLS. The device
first sends a SIP OPTION message to establish the TCP/TLS
connection and if it receives any SIP response, it continues
sending the CRLF keep-alive sequences.
configure voip > sip-definition
settings > ping-pong-keep-alive-
time
Defines the periodic interval (in seconds) after which a “ping”
(double-CRLF) keep-alive is sent to a proxy/registrar, using the
CRLF Keep-Alive mechanism.
