Version 7.2
Persistent TCP connection ensures less network traffic due to fewer
setting up and tearing down of TCP connections and reduced latency on
subsequent requests due to avoidance of initial TCP handshake. For TLS,
persistent connection may reduce the number of costly TLS handshakes
to establish security associations, in addition to the initial TCP connection
set up.
Note: If the destination is a Proxy server, the TCP/TLS connection is
persistent regardless of the settings of the parameter.
Defines the Timer B (INVITE transaction timeout timer) and Timer F (non-
INVITE transaction timeout timer), as defined in RFC 3261, when the SIP
transport type is TCP.
The valid range is 0 to 40 sec. The default is 64 * SipT1Rtx parameter
value. For example, if SipT1Rtx is set to 500 msec, then the default of
SIPTCPTimeout is 32 sec.
Defines the SIP destination port for sending initial SIP requests.
The valid range is 1 to 65534. The default port is 5060.
Note: SIP responses are sent to the port specified in the Via header.
Determines whether the 'user=phone' string is added to the SIP URI and
SIP To header.

[0] No = 'user=phone' string is not added.

[1] Yes = (Default) 'user=phone' string is part of the SIP URI and SIP
To header.
Determines whether the 'user=phone' string is added to the From and
Contact SIP headers.

[0] No = (Default) Doesn't add 'user=phone' string.

[1] Yes = 'user=phone' string is part of the From and Contact headers.
Determines the format of the URI in the P-Asserted-Identity and P-
Preferred-Identity headers.

[0] Disable = (Default) 'sip:'

[1] Enable = 'tel:'
Determines whether the Globally Routable User Agent URIs (GRUU)
mechanism is used, according to RFC 5627. This is used for obtaining a
GRUU from a registrar and for communicating a GRUU to a peer within a
dialog.

[0] Disable (default)

[1] Enable
A GRUU is a SIP URI that routes to an instance-specific UA and can be
reachable from anywhere. There are a number of contexts in which it is
desirable to have an identifier that addresses a single UA (using GRUU)
rather than the group of UA's indicated by an Address of Record (AOR).
