res_stir_shaken: Allow missing or anonymous CID to continue to the dialplan.
The verification check for missing or anonymous callerid was happening before
the endpoint's profile was retrieved which meant that the failure_action

was no callerid or it was "anonymous", the call was immediately terminated
instead of giving the dialplan the ability to decide what to do with the call.

the endpoint's stir_shaken_profile is available.

res_pjsip_authenticator_digest: Make correct error messages appear again.

with an Authorization header but the request still can't be matched to an

encryption of the CA private key so no passphrase is required.
Currently, when receiving an unauthenticated call, we keep track
of the negotiated format in the chosenformat, which allows us
to later create the channel using the right format. However,
this was not done for authenticated calls. This meant that in
certain circumstances, if we had not yet received a voice frame
from the peer, only certain other types of frames (e.g. text),
there were no variables containing the appropriate frame.
This led to problems in the jitterbuffer callback where we
unnecessarily bailed out of retrieving a frame from the jitterbuffer.
This was logic intentionally added in commit 73103bdcd5b342ce5dfa32039333ffadad551151
in response to an earlier regression, and while this prevents
crashes, it also backlogs legitimate frames unnecessarily.
The abort logic was initially added because at this point in the
code, we did not have the negotiated format available to us.
However, it should always be available to us as a last resort
in chosenformat, so we now pull it from there if needed. This
allows us to process frames the jitterbuffer even if voicefmt
and peerfmt aren't set and still avoid the crash. The failsafe
logic is retained, but now it shouldn't be triggered anymore.

Add C++ Standard detection to configure and fix a new C++20 compile issue

standard and testing other C++ capabilities but that package was never
included in the install_prereq script so many existing build environments
won't have it. Even if it is installed, older versions won't newer C++
standards and will actually cause an error if you try to test for that
version. To make it available for those environments, the
ax_cxx_compile_stdcxx.m4 macro has copied from the latest release of
autoconf-archive into the autoconf directory.
* A convenience wrapper(ast_cxx_check_std) around ax_cxx_compile_stdcxx was
also added so checking the standard version and setting the
asterisk-specific PBX_ variables becomes a one-liner:
`AST_CXX_CHECK_STD([std], [force_latest_std])`.
Calling that with a version of `17` for instance, will set PBX_CXX17
to 0 or 1 depending on whether the current c++ compiler supports stdc++17.
HAVE_CXX17 will also be 'defined" or not depending on the result.
* C++ compilers hardly ever default to the latest standard they support. g++
version 14 for instance supports up to C++23 but only uses C++17 by default.
If you want to use C++23, you have to add `-std=gnu++=23` to the g++
command line. If you set the second argument of AST_CXX_CHECK_STD to "yes",
the macro will automatically keep the highest `-std=gnu++` value that
worked and pass that to the Makefiles.

* Updated configure.ac to use AST_CXX_CHECK_STD() to check for C++

will set the second option to AST_CXX_CHECK_STD() to "yes". The default

chan_dahdi: Fix wrong channel state when RINGING recieved.
Previously, when AST_CONTROL_RINGING was received by
a DAHDI device, it would set its channel state to
AST_STATE_RINGING. However, an analysis of the codebase
and other channel drivers reveals RINGING corresponds to
physical power ringing, whereas AST_STATE_RING should be
used for audible ringback on the channel. This also ensures
the correct device state is returned by the channel state
to device state conversion.
Since there seems to be confusion in various places regarding
AST_STATE_RING vs. AST_STATE_RINGING, some documentation has
been added or corrected to clarify the actual purposes of these
two channel states, and the associated device state mapping.
An edge case that prompted this fix, but isn't explicitly
addressed here, is that of an incoming call to an FXO port.
The channel state will be "Ring", which maps to a device state
of "In Use", not "Ringing" as would be more intuitive. However,
this is semantic, since technically, Asterisk is treating this
the same as any other incoming call, and so "Ring" is the
semantic state (put another way, Asterisk isn't ringing anything,
like in the cases where channels are in the "Ringing" state).
Since FXO ports don't currently support Call Waiting, a suitable
workaround for the above would be to ignore the device state and
instead check the channel state (e.g. IMPORT(DAHDI/1-1,CHANNEL(state)))
since it will be Ring if the FXO port is idle (but a call is ringing
on it) and Up if the FXO port is actually in use. (In both cases,
the device state would misleadingly be "In Use".)

audiohook.c: resolving the issue with audiohook both reading when packet loss on one side of the call
When there is 0% packet loss on one side of the call and 15% packet loss on the other side, reading frame is often failed when reading direction_both audiohook. when read_factory available = 0, write_factory available = 320; i think write factory is usable read; because after reading one frame, there is still another frame that can be read together with the next read factory frame.

res_stir_shaken: Allow sending Identity headers for unknown TNs
Added a new option "unknown_tn_attest_level" to allow Identity
headers to be sent when a callerid TN isn't explicitly configured
in stir_shaken.conf. Since there's no TN object, a private_key_file
and public_cert_url must be configured in the attestation or profile

Since "unknown_tn_attest_level" uses the same enum as attest_level,
some of the sorcery macros had to be refactored to allow sharing
the enum and to/from string conversion functions.

pjsip_transport_events: Avoid monitor destruction
When a transport is disconnected, several events can arrive following
each other. The first event will be PJSIP_TP_STATE_DISCONNECT and it
will trigger the destruction of the transport monitor object. The lookup
for the transport monitor to destroy is done using the transport key,
that contains the transport destination host:port.
A reconnect attempt by pjsip will be triggered as soon something needs to
send a packet using that transport. This can happen directly after a
disconnect since ca
Subsequent events can arrive later like PJSIP_TP_STATE_DESTROY and will
also try to trigger the destruction of the transport monitor if not
already done. Since the lookup for the transport monitor to destroy is
done using the transport key, it can match newly created transports
towards the same destination and destroy their monitor object.
Because of this, it was sometimes not possible to monitor a transport
after one or more disconnections.
This fix adds an additional check on the transport pointer to ensure
only a monitor for that specific transport is removed.

However, modern libSRTP (as of 1.0.1[1]) now mentions the following in
their README.md[2]:
