VARIABLE: bypass_media_sdp_filter
Can be set globally or per leg on the inbound side of a bypass_media bridge.
VALID FILTERS:
remove(): Removes the specified codec if it exists in the SDP.
only(): Removes all codecs besides the one specified (providing that it exists in the sdp) (will not remove telephone-event))
EXAMPLE 1 (remove everything leaving only g729):
<action application="set" data="bypass_media_sdp_filter=only(g729)"/>
<action application="set" data="bypass_media=true"/>
<action application="bridge" data="sofia/internal/1238@conference.freeswitch.org"/>
EXAMPLE 2 (remove everything leaving only g729 and also remove dtmf):
<action application="set" data="bypass_media_sdp_filter=only(g729)|remove(telephone-event)"/>
<action application="set" data="bypass_media=true"/>
<action application="bridge" data="sofia/internal/1238@conference.freeswitch.org"/>
EXAMPLE 3 (remove alaw and speex):
<action application="set" data="bypass_media_sdp_filter=remove(pcma)|remove(speex)"/>
<action application="set" data="bypass_media=true"/>
<action application="bridge" data="sofia/internal/1238@conference.freeswitch.org"/>
The `switch_split_date` and `switch_split_time` functions only set as
many variables as they believe exist values in the input string.
Since we didn't have defaults assigned we would read undefined stack
memory if the input string didn't contain e.g. an hour.
With this commit, we use 1970 if no year is present, January if no
month is present, the first day of the month if none is given, and
zero for each of a missing hour, minute, or second.
We're moving the variable declarations down to the smallest possible
scope (a good idea in general) so we can address the use of undefined
memory by the function in a later commit.
* commit '1affff9db4aaa29ab66f9f5db76f575eeabd86b5':
Fixed a clang-3.5 missing-prototype warning and added doxygen documentation for switch_channel_set_presence_data_vals. #doxygen
Fixed dead code.
Fixed trucation of value warning.
Removed a useless called to abs.
Removed an autological-pointer-compare from src/switch_utils.c.
Fixed trucation of value warning.
Building with Clang 3.5 gave the following warning: error: comparison
of array 'iface_out.sin6_addr.__in6_u.__u6_addr8' equal to a null
pointer is always false [-Werror,-Wtautological-pointer-compare]
This is a problem because as it is written the check will never be
true. A pointer to a structure within a structure will never be null. The
intention was either to null check the pointer or to check if the IP
address itself was not zero.
From context in the code this appeared to be a pointer null check so I
removed it.
We were incorrectly parsing usernames and domains starting with "sip"
if there was no sip: or sips: scheme in the string.
We were also incorrectly parsing usernames containing a colon even if
a scheme was given.
This also refactors the function for hopefully greater clarity.
In commit 7efeabbd88 Anthony fixed the
handling of sip:example.com and sips:example.com URLs, however he
introduced a regression causing URLs starting with 's' to be parsed
incorrectly.
In commit 7d2456ea27 Brian fixed the
regression, but introduced a regression causing sips:example.com URLs
to be handled incorrectly.
Note that the function switch_util_quote_shell_arg is implemented
incorrectly for unix shells, so this is still not safe until that
function is fixed.
