you apply SIP message manipulation rules on incoming SIP initiating-
dialog request messages (not in-dialog), received on this SIP
Interface, prior to the Classification process.
By default, no Message Manipulation Set ID is defined.
To configure Message Manipulation rules, see Configuring SIP
Message Manipulation on page 378.
Note:

The Message Manipulation Set assigned to a SIP Interface that is
associated with an outgoing call, is ignored. Only the Message
Manipulation Set assigned to the associated IP Group is applied to
the outgoing call.

If both the SIP Interface and IP Group associated with the incoming
call are assigned a Message Manipulation Set, the one assigned to
the SIP Interface is applied first.

The parameter is applicable only to the SBC application.
Assigns a Media Realm to the SIP Interface.
By default, no value is defined.
To configure Media Realms, see 'Configuring Media Realms' on page
319.
Enables direct media (RTP/SRTP) flow (i.e., no Media Anchoring)
between endpoints associated with the SIP Interface.

[0] Disable = (Default) Media Anchoring is employed, whereby the
media stream traverses the device (and each leg uses a different
coder or coder parameters).

[1] Enable = No Media Anchoring. Media stream flows directly
between endpoints (i.e., does not traverse the device - no Media
Anchoring).

[2] Enable when Same NAT = No Media Anchoring. Media stream
flows directly between endpoints if they are located behind the
same NAT.
Note:

If the parameter is enabled for direct media and the two endpoints
belong to the same SIP Interface, calls cannot be established if the
following scenario exists:
a. One of the endpoints is defined as a foreign user (for example,
"follow me service")
b. and one endpoint is located on the WAN and the other on the
LAN.
The reason for the above is that in direct media, the device does
not interfere in the SIP signaling such as manipulation of IP
addresses, which is necessary for calls between LAN and WAN.

To enable direct media for all calls, use the global parameter
SBCDirectMedia. If enabled, even if the SIP Interface is disabled
for direct media, direct media is employed for calls belonging to the
SIP Interface.

For more information on direct media, see Direct Media on page
626.

The parameter is applicable only to the SBC application.
