Description
Defines the string that is used in the SIP request header User-Agent
and SIP response header Server. If not configured, the default string
3Com product-name s/w-version is used (for example, User-Agent:
3Com-Sip-Gateway-V7111 18 PORT FXS/v.4.80.004.008). When
configured, the string UserAgentDisplayInfo s/w-version is used (for
example, User-Agent: MyNewOEM/v.4.80.004.008). Note that the
version number can't be modified.
The maximum string length is 50 characters.
Defines the value of the Subject header in outgoing INVITE
messages. If not specified, the Subject header is not included
(default).
The maximum length of the subject is limited to 50 characters.
Enables or disables the usage of the SIP Reason header.
Valid options include:
[0] = Disable
[1] = Enable (default)
Determines the gateway behavior when Transfer is initiated while still
in Alerting state. Valid options include:
Disable [0] = Send REFER with Replaces (default).
Enable [1] = Send CANCEL, and after a 487 response is received,
send REFER without Replaces.
Determines the gateway's behavior when a 3xx response is received
for an outgoing INVITE request. The gateway can either use the
same call identifiers (CallID, branch, to and from tags) or change
them in the new initiated INVITE.
0 (forward) = Use different call identifiers for a redirected INVITE
message (default).
1 (redirect) = Use the same call identifiers.
Determines whether the 'mptime' attribute is included in the outgoing
SDP. Valid options include:
[0] = Disable (default)
[1] = Enable (includes the mptime attribute in the outgoing SDP --
PacketCable defined format)
The 'mptime' attribute enables the IP gateway to define a separate
Packetization period for each negotiated coder in the SDP. The
'mptime' attribute is only included if this parameter is enabled, even if
the remote side includes it in the SDP offer. Upon reception, each
coder receives its 'ptime' value in the following precedence:
From 'mptime' attribute
From 'ptime' attribute
Default value
