User's Manual 23. Coders and Profiles
Parameter Description
SBC Fax
Fax Rerouting Mode
sbc-fax-rerouting-mode
[IpProfile_SBCFaxReroutingMod
e]
Enables the rerouting of incoming SBC calls that are identified as
fax calls to a new IP destination.

[0] Disable (default)

[1] Rerouting without delay
For more information, see Configuring Rerouting of Calls to Fax
Destinations on page 684.
Note: Configure the parameter for the IP leg that is interfacing
with the fax termination.
Media
Broken Connection Mode
disconnect-on-broken-connection
[IpProfile_DisconnectOnBrokenC
onnection]
Defines the device's handling of calls when RTP packets (media)
are not received within a user-defined timeout (configured by the
BrokenConnectionEventTimeout parameter). The interval can be
during call setup (configured by the NoRTPDetectionTimeout
parameter) or mid-call when RTP flow suddenly stops
(configured by the BrokenConnectionEventTimeout parameter).

[0] Ignore = The call is maintained despite no media and is
released when signaling ends the call (i.e., SIP BYE).

[1] Disconnect = (Default) The device ends the call.

[2] Reroute = (SBC application only) The device ends the call
and searches the IP-to-IP Routing table for a matching rule
and if found, generates a new INVITE to the corresponding
destination (i.e., alternative routing). You can configure a
routing rule whose matching characteristics is explicitly for
calls with broken RTP connections. This is done using the
Call Trigger parameter, as described in Configuring SBC IP-
to-IP Routing Rules on page 671.
Note:

The device can only detect a broken RTP connection if
silence compression is disabled for the RTP session.

If during a call the source IP address (from where the RTP
packets are received by the device) is changed without
notifying the device, the device rejects these RTP packets. To
overcome this, configure the DisconnectOnBrokenConnection
parameter to 0. By this configuration, the device doesn't
detect RTP packets arriving from the original source IP
address and switches (after 300 msec) to the RTP packets
arriving from the new source IP address.

The corresponding global parameter is
DisconnectOnBrokenConnection.
Media IP Version Preference
media-ip-version-preference
[IpProfile_MediaIPVersionPrefere
nce]
Defines the preferred RTP media IP addressing version for
outgoing SIP calls (according to RFC 4091 and RFC 4092). The
RFCs concern Alternative Network Address Types (ANAT)
semantics in the SDP to offer groups of network addresses (IPv4
and IPv6) and the IP address version preference to establish the
media stream. The IP address is indicated in the "c=" field
(Connection) of the SDP.

[0] Only IPv4 = (Default) SDP offer includes only IPv4 media
IP addresses.

[1] Only IPv6 = SDP offer includes only IPv6 media IP
