sip-definition
settings > rport-
support
[EnableRport]

[0] = Disabled (default)

[1] = Enabled
The device adds an 'rport' parameter to the Via header of each outgoing
SIP message. The first Proxy that receives this message sets the 'rport'
value of the response to the actual port from where the request was
received. This method is used, for example, to enable the device to
identify its port mapping outside a NAT.
If the Via header doesn't include the 'rport' parameter, the destination
port of the response is obtained from the host part of the Via header.
If the Via header includes the 'rport' parameter without a port value, the
destination port of the response is the source port of the incoming
request.
If the Via header includes 'rport' with a port value (e.g., rport=1001), the
destination port of the response is the port indicated in the 'rport'
parmeter.
Enable X-Channel Header
configure voip > sip-
definition settings > x-
channel-header
[XChannelHeader]
Enables the device to add the SIP X-Channel header to outgoing SIP
messages. The header provides information on the physical Trunk/B-
channel on which the call is received or sent.

[0] Disable = (Default) X-Channel header is not used.

[1] Enable = X-Channel header is generated by the device and sent
in SIP INVITE requests and 180, 183, and 200 OK responses. The
header includes the Trunk number, B-channel and the device's IP
address, using the following syntax:
x-channel: ds/ds1-
<digital Trunk number>
/<
B-channel or
channel
>;IP=<device's IP address>
For example, the below shows a call on Trunk 1, channel 4 of the
device with IP address 192.168.13.1:
x-channel: ds/ds1-1/4;IP=192.168.13.1
Progress Indicator to IP
configure voip > sip-
definition settings > prog-
ind-2ip
[ProgressIndicator2IP]
Global parameter defining the progress indicator (PI) sent to the IP.
You can also configure the feature per specific calls, using IP Profiles
(IpProfile_ProgressIndicator2IP) or Tel Profiles
(TelProfile_ProgressIndicator2IP). For a detailed description of the
parameter and for configuring the feature, see Configuring IP Profiles
on page 404 or Configuring Tel Profiles on page 440.
Note: If this feature is configured for a specific profile, the settings of
this global parameter is ignored for calls associated with the profile.
[EnableRekeyAfter181] Enables the device to send a re-INVITE with a new (different) SRTP key
(in the SDP) if a SIP 181 response is received ("call is being
forwarded"). The re-INVITE is sent immediately upon receipt of the 200
OK (when the call is answered).

[0] = Disable (default)

[1] = Enable
Note: The parameter is applicable only if SRTP is used.
configure voip >
sip-definition
settings > number-
of-active-dialogs
[NumberOfActiveDialogs]
Defines the maximum number of concurrent, outgoing SIP REGISTER
dialogs. The parameter is used to control the registration rate.
The valid range is 1 to 20. The default is 20.
Note:

Once a 200 OK is received in response to a REGISTER message,
the REGISTER message is not considered in this maximum count
limit.

The parameter applies only to outgoing REGISTER messages (i.e.,
incoming is unlimited).
