Function Documentation
◆ __ast_answer()
| int __ast_answer | ( | struct ast_channel * | chan, |
| unsigned int | delay | ||
| ) |
Answer a channel, with a selectable delay before returning.
- Parameters
-
chan channel to answer delay maximum 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
-
0 on success non-zero on 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_chan Channel to place into autoservice while the sub is running. It is perfectly safe for this to be NULL sub_chan The channel to run the subroutine on. Also the channel from which we determine which subroutine we need to run. connected_info Either an ast_party_connected_line or ast_frame pointer of type AST_CONTROL_CONNECTED_LINE frame If true, then connected_info is an ast_frame pointer, otherwise it is an ast_party_connected_line pointer.
- Return values
-
0 Success -1 Either the subroutine does not exist, or there was an error while attempting to run the subroutine

◆ ast_channel_get_by_name_prefix()
| struct ast_channel * ast_channel_get_by_name_prefix | ( | const char * | name, |
| size_t | name_len | ||
| ) |
Find a channel by a name prefix.
- Parameters
-
search The channel name or uniqueid prefix to search for len Only search for up to this many characters from the search term
Search for a channel that has the same name prefix as specified by the search term. If not found, search for an exact match on the uniqueid. Searching by partial uniqueid doesn't make any sense as it's usually a system-name plus a timestamp and is not supported.
- Return values
-
a channel with a matching name or uniqueid NULL if no channel was found
- Note
- The fallback search by uniqueid is a historical thing. If you know the search term is a uniqueid, use ast_channel_get_by_uniqueid instead.

| 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
-
chan The channel for which we wish to retrieve the agent type [out] agent_type The type of agent the channel driver wants us to use size The size of the buffer to write to

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
-
chan The channel to retrieve the information from [out] device_name The buffer to place the device's name into name_buffer_length The allocated space for the device_name

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

◆ 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
-
yankee The channel to gain control of
- Return values
-
NULL Could not gain control of the channel non-NULL The channel

- Parameters
-
chan channel to queue frame onto control type of control frame data pointer to payload data to be included in frame datalen number of bytes of payload data
- Return values
-
0 success non-zero failure
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.

| struct ast_frame * ast_read_noaudio | ( | struct ast_channel * | chan | ) |
Reads a frame, returning AST_FRAME_NULL frame if audio.
- Parameters
-
chan channel 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
- Audio is replaced with AST_FRAME_NULL to avoid transcode when the resulting audio is not necessary.
