When enabled, the sip_external_media logic will leave SDP payload untouched when it detects that interface towards INVITEd party is the same with the one towards media endpoint. The typical scenario for this logic is when a LAN SIP agent has more than one IP address (uses a different address for media streams than the one used on signalling stream) and it also forwards calls to a voice mailbox located on the WAN side. In such case sip_direct_media must be disabled (so normal calls could be handled by the SIP helper), but media streams that are not traversing this router must also be excluded from address translation (e.g. call forwards).

README
Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
