– res_pjsip: disable raw bad packet logging

User Notes:
—————————————-

– ### app_read: Add an option to return terminator on empty digits.
A new option ‘e’ has been added to allow Read() to return the
terminator as the dialed digits in the case where only the terminator
is entered.

– ### format_sln: add .slin as supported file extension
format_sln now recognizes ‘.slin’ as a valid
file extension in addition to the existing
‘.sln’ and ‘.raw’.

– ### app_directory: Add a ‘skip call’ option.
A new option ‘s’ has been added to the Directory() application that
will skip calling the extension and instead set the extension as
DIRECTORY_EXTEN channel variable.

– ### app_senddtmf: Add option to answer target channel.
A new option has been added to SendDTMF() which will answer the
specified channel if it is not already up. If no channel is specified,
the current channel will be answered instead.

– ### cli: increase channel column width
This change increases the display width on ‘core show channels’
amd ‘core show channels verbose’
For ‘core show channels’, the Channel name field is increased to
64 characters and the Location name field is increased to 32
characters.
For ‘core show channels verbose’, the Channel name field is
increased to 80 characters, the Context is increased to 24
characters and the Extension is increased to 24 characters.

– ### bridge_builtin_features: add beep via touch variable
Add optional touch variable : TOUCH_MIXMONITOR_BEEP(interval)
Setting TOUCH_MIXMONITOR_BEEP/TOUCH_MONITOR_BEEP to a valid
interval in seconds will result in a periodic beep being
played to the monitored channel upon MixMontior/Monitor
feature start.
If an interval less than 5 seconds is specified, the interval
will default to 5 seconds. If the value is set to an invalid
interval, the default of 15 seconds will be used.

– ### test.c: Fix counting of tests and add 2 new tests
The “tests” attribute of the “testsuite” element in the
output XML now reflects only the tests actually requested
to be executed instead of all the tests registered.
The “failures” attribute was added to the “testsuite”
element.
Also added two new unit tests that just pass and fail
to be used for testing CI itself.

– ### res_mixmonitor: MixMonitorMute by MixMonitor ID
It is now possible to specify the MixMonitorID when calling
the manager action: MixMonitorMute. This will allow an
individual MixMonitor instance to be muted via ID.
The MixMonitorID can be stored as a channel variable using
the ‘i’ MixMonitor option and is returned upon creation if
this option is used.
As part of this change, if no MixMonitorID is specified in
the manager action MixMonitorMute, Asterisk will set the mute
flag on all MixMonitor audiohooks on the channel. Previous
behavior would set the flag on the first MixMonitor audiohook
found.
