This function should ONLY be used to create a fake channel that can then be populated with data for use in variable substitution when a real channel does not exist.
The created dummy channel should be destroyed by ast_channel_unref(). Using ast_channel_release() needlessly grabs the channel container lock and can cause a deadlock as a result. Also grabbing the channel container lock reduces system performance.

◆ anonymous enum

anonymous enum

ast_channel flags

Enumerator
AST_FLAG_DEFER_DTMF 

Queue incoming DTMF, to be released when this flag is turned off

AST_FLAG_WRITE_INT 

write should be interrupt generator

AST_FLAG_BLOCKING 

a thread is blocking on this channel

AST_FLAG_ZOMBIE 

This is a zombie channel

AST_FLAG_EXCEPTION 

There is an exception pending

AST_FLAG_MOH 

Listening to moh XXX anthm promises me this will disappear XXX

AST_FLAG_SPYING 

This channel is spying on another channel

AST_FLAG_IN_AUTOLOOP 

the channel is in an auto-incrementing dialplan processor, so when ->priority is set, it will get incremented before finding the next priority to run

AST_FLAG_OUTGOING 

This is an outgoing call

AST_FLAG_IN_DTMF 

A DTMF_BEGIN frame has been read from this channel, but not yet an END

AST_FLAG_EMULATE_DTMF 

A DTMF_END was received when not IN_DTMF, so the length of the digit is currently being emulated

AST_FLAG_END_DTMF_ONLY 

This is set to tell the channel not to generate DTMF begin frames, and to instead only generate END frames.

AST_FLAG_MASQ_NOSTREAM 

This flag indicates that on a masquerade, an active stream should not be carried over

AST_FLAG_BRIDGE_HANGUP_RUN 

This flag indicates that the hangup exten was run when the bridge terminated, a message aimed at preventing a subsequent hangup exten being run at the pbx_run level

AST_FLAG_DISABLE_WORKAROUNDS 

Disable certain workarounds. This reintroduces certain bugs, but allows some non-traditional dialplans (like AGI) to continue to function.

AST_FLAG_DISABLE_DEVSTATE_CACHE 

Disable device state event caching. This allows channel drivers to selectively prevent device state events from being cached by certain channels such as anonymous calls which have no persistent represenatation that can be tracked.

AST_FLAG_BRIDGE_DUAL_REDIRECT_WAIT 

This flag indicates that a dual channel redirect is in progress. The bridge needs to wait until the flag is cleared to continue.

AST_FLAG_ORIGINATED 

This flag indicates that the channel was originated.

AST_FLAG_DEAD 

The channel is well and truly dead. Once this is set and published, no further actions should be taken upon the channel, and no further publications should occur.

AST_FLAG_SNAPSHOT_STAGE 

Channel snapshot should not be published, it is being staged for an explicit publish.

AST_FLAG_TIMINGDATA_IS_AO2_OBJ 

The data on chan->timingdata is an astobj2 object.

AST_FLAG_SUBROUTINE_EXEC 

The channel is executing a subroutine or macro

Function Documentation

◆ __ast_answer()

int __ast_answer ( struct ast_channel *  chan,
unsigned int  delay 
)

Answer a channel, with a selectable delay before returning.

Parameters
chanchannel to answer
delaymaximum amount of time to wait for incoming media

This function answers a channel and handles all necessary call setup functions.

Note
The channel passed does not need to be locked, but is locked by the function when needed.
This function will wait up to 'delay' milliseconds for media to arrive on the channel before returning to the caller, so that the caller can properly assume the channel is 'ready' for media flow. If 'delay' is less than 500, the function will wait up to 500 milliseconds.
Return values
0on success
non-zeroon failure

◆ ast_answer()

int ast_answer ( struct ast_channel *  chan)

Answer a channel.

Parameters
chanchannel to answer

This function answers a channel and handles all necessary call setup functions.

Note
The channel passed does not need to be locked, but is locked by the function when needed.
This function will wait up to 500 milliseconds for media to arrive on the channel before returning to the caller, so that the caller can properly assume the channel is 'ready' for media flow.
Return values
0on success
non-zeroon failure

Run a connected line interception subroutine and update a channel's connected line information.

Since
11

Whenever we want to update a channel's connected line information, we may need to run a subroutine so that an administrator can manipulate the information before sending it out. This function both runs the subroutine specified by CONNECTED_LINE_SEND_SUB and sends the update to the channel.

Parameters
autoservice_chanChannel to place into autoservice while the sub is running. It is perfectly safe for this to be NULL
sub_chanThe channel to run the subroutine on. Also the channel from which we determine which subroutine we need to run.
connected_infoEither an ast_party_connected_line or ast_frame pointer of type AST_CONTROL_CONNECTED_LINE
frameIf true, then connected_info is an ast_frame pointer, otherwise it is an ast_party_connected_line pointer.
Return values
0Success
-1Either the subroutine does not exist, or there was an error while attempting to run the subroutine

◆ ast_channel_dialed_causes_add()

int ast_channel_dialed_causes_add ( const struct ast_channel *  chan,
const struct ast_control_pvt_cause_code *  cause_code,
int  datalen 
)

Add cause code information to the channel.

Since
11

This function makes use of datastore operations on the channel, so it is important to lock the channel before calling this function. The passed in data is copied and so is still owned by the caller.

Parameters
chanThe channel on which to add information
cause_codeThe cause information to be added to the channel
datalenThe total length of the structure since its length is variable
Return values
0on success
-1on error

◆ ast_channel_dialed_causes_iterator()

struct ao2_iterator ast_channel_dialed_causes_iterator ( const struct ast_channel *  chan)

Retrieve an iterator for dialed cause information.

Since
20.19.0
22.9.0
23.3.0

Each call to ao2_iterator_next() will return a pointer to an ast_control_pvt_cause_code structure containing the dialed cause information for one channel. One of the entries may be for the channel itself if the channel was hung up because of a non-2XX SIP response code. The rest of the entries will be for channels bridged to the channel for which dialed cause information is being retrieved. The caller is responsible for cleaning up the reference count of each entry returned and destroying the returned iterator with ao2_iterator_destroy() when it is finished with it.

Parameters
chanThe channel from which to retrieve cause information
Return values
ao2_iterator

◆ ast_channel_get_cc_agent_type()

int ast_channel_get_cc_agent_type ( struct ast_channel *  chan,
char *  agent_type,
size_t  size 
)

Find the appropriate CC agent type to use given a channel.

Since
1.8

During call completion, we will need to create a call completion agent structure. To figure out the type of agent to construct, we need to ask the channel driver for the appropriate type.

Prior to adding this function, the call completion core attempted to figure this out for itself by stripping the technology off the channel's name. However, in the case of chan_dahdi, there are multiple agent types registered, and so simply searching for an agent type called "DAHDI" is not possible. In a case where multiple agent types are defined, the channel driver must have a queryoption callback defined in its channel_tech, and the queryoption callback must handle AST_OPTION_CC_AGENT_TYPE

If a channel driver does not have a queryoption callback or if the queryoption callback does not handle AST_OPTION_CC_AGENT_TYPE, then the old behavior of using the technology portion of the channel name is used instead. This is perfectly suitable for channel drivers whose channel technologies are a one-to-one match with the agent types defined within.

Note that this function is only called when the agent policy on a given channel is set to "native." Generic agents' type can be determined automatically by the core.

Parameters
chanThe channel for which we wish to retrieve the agent type
[out]agent_typeThe type of agent the channel driver wants us to use
sizeThe size of the buffer to write to

◆ ast_channel_get_device_name()

int ast_channel_get_device_name ( struct ast_channel *  chan,
char *  device_name,
size_t  name_buffer_length 
)

Get a device name given its channel structure.

Since
1.8

A common practice in Asterisk is to determine the device being talked to by dissecting the channel name. For certain channel types, this is not accurate. For instance, an ISDN channel is named based on what B channel is used, not the device being communicated with.

This function interfaces with a channel tech's queryoption callback to retrieve the name of the device being communicated with. If the channel does not implement this specific option, then the traditional method of using the channel name is used instead.

Parameters
chanThe channel to retrieve the information from
[out]device_nameThe buffer to place the device's name into
name_buffer_lengthThe allocated space for the device_name
Returns
0 always

◆ ast_channel_get_intercept_mode()

int ast_channel_get_intercept_mode ( void  )

A dialplan intercept routine is equivalent to an interrupt routine. As such, the routine must be done quickly and you do not have access to the media stream. These restrictions are necessary because the media stream is the responsibility of some other code and interfering with or delaying that processing is bad.

Return values
0Not in an intercept routine.

Variables whose names begin with a single '_' are copied into the child channel with the prefix removed. Variables whose names begin with '__' are copied into the child channel with their names unchanged.

)

Move a channel from its current location to a new location.

Since
12

The intention of this function is to have the destination channel take on the identity of the source channel.

Note
This function is NOT intended to be used on bridged channels. If you wish to move an unbridged channel into the place of a bridged channel, then use ast_bridge_join() or ast_bridge_impart(). If you wish to move a bridged channel into the place of another bridged channel, then use ast_bridge_move().
When this function returns succesfully, the source channel is in a state where its continued use is unreliable.
absolutely NO channel locks should be held before calling this function.
Parameters
destThe place to move the source channel
sourceThe channel to move
Return values
0Success

◆ ast_channel_oldest_linkedid()

const char * ast_channel_oldest_linkedid ( const char *  a,
const char *  b 
)

Return the oldest linkedid between two channels.

A channel linkedid is derived from the channel uniqueid which is formed like this: [systemname-]ctime.seq

The systemname, and the dash are optional, followed by the epoch time followed by an integer sequence. Note that this is not a decimal number, since 1.2 is less than 1.11 in uniqueid land.

To compare two uniqueids, we parse out the integer values of the time and the sequence numbers and compare them, with time trumping sequence.

Parameters
aThe linkedid value of the first channel to compare
bThe linkedid value of the second channel to compare
Return values
NULLon failure
Theoldest linkedid value
Since
12.0.0

int ast_channel_redirecting_sub ( struct ast_channel *  autoservice_chan,
struct ast_channel *  sub_chan,

)

Run a redirecting interception subroutine and update a channel's redirecting information.

Since
11

Whenever we want to update a channel's redirecting information, we may need to run a subroutine so that an administrator can manipulate the information before sending it out. This function both runs the subroutine specified by REDIRECTING_SEND_SUB and sends the update to the channel.

Parameters
autoservice_chanChannel to place into autoservice while the subroutine is running. It is perfectly safe for this to be NULL
sub_chanThe channel to run the subroutine on. Also the channel from which we determine which subroutine we need to run.
redirecting_infoEither an ast_party_redirecting or ast_frame pointer of type AST_CONTROL_REDIRECTING
is_frameIf true, then redirecting_info is an ast_frame pointer, otherwise it is an ast_party_redirecting pointer.
Return values
0Success
-1Either the subroutine does not exist, or there was an error while attempting to run the subroutine

int ast_channel_request_stream_topology_change ( struct ast_channel *  chan,
struct ast_stream_topology *  topology,
void *  change_source 
)

Request that the stream topology of a channel change.

Parameters
chanThe channel to change
topologyThe new stream topology
change_sourceThe source that initiated the change
Note
Absolutely NO channel locks should be held before calling this function.
Return values
0request has been accepted to be attempted
-1request could not be attempted
Note
This function initiates an asynchronous request to change the stream topology. It is not guaranteed that the topology will change and until an AST_CONTROL_STREAM_TOPOLOGY_CHANGED frame is received from the channel the current handler of the channel must tolerate the stream topology as it currently exists.
This interface is provided for applications and resources to request that the topology change. It is not for use by the channel driver itself.

◆ ast_channel_yank()

struct ast_channel * ast_channel_yank ( struct ast_channel *  yankee)

Gain control of a channel in the system.

Since
12

The intention of this function is to take a channel that currently is running in one thread and gain control of it in the current thread. This can be used to redirect a channel to a different place in the dialplan, for instance.

Note
This function is NOT intended to be used on bridged channels. If you need to control a bridged channel, you can set a callback to be called once the channel exits the bridge, and run your controlling logic in that callback

XXX Put name of callback-setting function in above paragraph once it is written

Note
When this function returns successfully, the yankee channel is in a state where it cannot be used any further. Always use the returned channel instead.
absolutely NO channel locks should be held before calling this function.
The dialplan location on the returned channel is where the channel should be started in the dialplan if it is returned to it.
Parameters
yankeeThe channel to gain control of
Return values
NULLCould not gain control of the channel
non-NULLThe channel

◆ ast_hangup()

void ast_hangup ( struct ast_channel *  chan)

Hang up a channel.

Note
Absolutely NO channel locks should be held before calling this function.
This function performs a hard hangup on a channel. Unlike the soft-hangup, this function performs all stream stopping, etc, on the channel that needs to end. chan is no longer valid after this call.
Parameters
chanchannel to hang up (NULL tolerant)

Hang up a channel.

◆ ast_is_deferrable_frame()

int ast_is_deferrable_frame ( const struct ast_frame *  frame)

Should we keep this frame for later?

There are functions such as ast_safe_sleep which will service a channel to ensure that it does not have a large backlog of queued frames. When this happens, we want to hold on to specific frame types and just drop others. This function will tell if the frame we just read should be held onto.

Parameters
frameThe frame we just read
Return values
1frame should be kept
0frame should be dropped

◆ ast_queue_control_data()

int ast_queue_control_data ( struct ast_channel *  chan,

Parameters
chanchannel to queue frame onto
controltype of control frame
datapointer to payload data to be included in frame
datalennumber of bytes of payload data
Return values
0success
non-zerofailure

The supplied payload data is copied into the frame, so the caller's copy is not modified nor freed, and the resulting frame will retain a copy of the data even if the caller frees their local copy.

Note
This method should be treated as a 'network transport'; in other words, your frames may be transferred across an IAX2 channel to another system, which may be a different endianness than yours. Because of this, you should ensure that either your frames will never be expected to work across systems, or that you always put your payload data into 'network byte order' before calling this function.
The channel does not need to be locked before calling this function.

◆ ast_raw_answer()

int ast_raw_answer ( struct ast_channel *  chan)

Answer a channel.

Parameters
chanchannel to answer

This function answers a channel and handles all necessary call setup functions.

Note
The channel passed does not need to be locked, but is locked by the function when needed.
Unlike ast_answer(), this function will not wait for media flow to begin. The caller should be careful before sending media to the channel before incoming media arrives, as the outgoing media may be lost.
Return values
0on success
non-zeroon failure

◆ ast_read()

struct ast_frame * ast_read ( struct ast_channel *  chan)

Reads a frame.

Parameters
chanchannel to read a frame from
Returns
Returns a frame, or NULL on error. If it returns NULL, you best just stop reading frames and assume the channel has been disconnected.
Note
This function will filter frames received from the channel so that only frames from the default stream for each media type are returned. All other media frames from other streams will be absorbed internally and a NULL frame returned instead.

timeouthow long to timeout between digits
rtimeouttimeout to wait on the first digit
endersdigits to end the string

Read in a digit string "s", max length "len", maximum timeout between digits "timeout" (-1 for none), terminated by anything in "enders". Give them rtimeout for the first digit.

Returns
Returns 0 on normal return, or 1 on a timeout. In the case of a timeout, any digits that were read before the timeout will still be available in s. RETURNS 2 in full version when ctrlfd is available, NOT 1

◆ ast_softhangup()

int ast_softhangup ( struct ast_channel *  chan,
int  cause 
)

Softly hangup up a channel.

Parameters
chanchannel to be soft-hung-up
causean AST_SOFTHANGUP_* reason code

Call the protocol layer, but don't destroy the channel structure (use this if you are trying to safely hangup a channel managed by another thread.

Warning
The channel passed to this function must NOT be locked. ast_softhangup() calls ast_rtp_instance_set_stats_vars() to set RTP QOS variables. If this channel is in a bridge, ast_rtp_instance_set_stats_vars() will attempt to lock the bridge peer as well as this channel. This can cause a lock inversion if we already have this channel locked and another thread tries to set bridge variables on the peer because it will have locked the peer first, then this channel. For this reason, we must NOT have the channel locked when we call ast_softhangup().
Returns
Returns 0 regardless

Softly hangup up a channel.
